+E2fsprogs 1.42.13 (May 17, 2015)
+================================
+
+Fixed a potential buffer overflow while closing a file system in
+libext2fs.  (CVE-2015-1572, Addresses Debian Bug: #778948)
+
+Fixed a bug which could cause e2fsck to corrupt Hurd file systems.
+(Addresses Debian Bug: #760275)
+
+Fixed a deadlock which occurs when using systemd and e2fsck.conf's
+logging feature.  (Addresses Debian Bug: #775234)
+
+Fixed a bug which could cause programs using libext2's inode table
+scanning functions from crashing on certain corrupted file systems.
+(Addresses Debian Bug: #773795)
+
+Fixed dumpe2fs so it won't crash if the user doesn't specify a block
+device (file system).  (Addresses Debian Bug: #764293)
+
+Fixed e2fsck so if it notices unexpected HTREE blocks in pass 2, it
+will report the correct directory inode containing the inconsistency.
+
+If e2fsck fails to grow the dir_info structure due realloc(3) not
+having enough memory, it will now fail with explanatory message
+instead of staggering on failing with a confusing internal error
+messages.
+
+The tune2fs program will zero out the superblock journal backup
+information when removing a journal from a file system.
+
+The mke2fs program now enables the large_file feature by default.
+
+Fixed a bug which could cause badblocks to crash if there are millions
+and millions of bad blocks.
+
+Fixed some use-after-free bug in resize2fs and e2fsck.
+
+Fixed a memory leak in tune2fs.
+
+Fixed some bigendian bugs that had crept into both indirect and extent
+handling inside libext2fs.
+
+Updated/fixed various man pages.
+
+Update Esperanto, German, and Spanish translations.  Added Danish
+translation.
+
+Programmer's Notes
+------------------
+
+Fixed coverity, sparse, gcc -Wall, and clang warnings/nits.
+
+Clean up some build system problems (build failures with various
+configure options, fix Posix portability issues, etc.)
+
+The functions ext2fs_inode_alloc_stats[2]() and
+ext2fs_block_alloc_stats[2]() now check the inode and block numbers
+passed to them, to avoid crashes caused by buggy callers.
+
+The libext2fs directory iterator will now check for an invalid
+directory entry length instead of possibly walking off the end of the
+directory buffer.
+
+
+E2fsprogs 1.42.12 (August 25, 2014)
+===================================
+
+Fix various e2fsck bugs when trying to repair bigalloc file systems.
+
+E2fsck can now repair a file system with an overly large
+s_first_meta_bg field, which had previously caused all e2fsprogs
+programs to crash when trying to open such a file system.
+
+Fix e2fsck so that it can correctly fix a number of rare file system
+corruptions that were discovered when using a file system fuzzer.
+
+Fix e2fsck so it does not try to write back block group descriptors if
+they have not been modified.
+
+Mke2fs program will now place metadata blocks in the last flex_bg so
+they are contiguous.  This reduces free space fragmentation in a
+freshly created file system, as well as allowing mke2fs commands which
+request extremely large flex_bg size to succeed.
+
+Mke2fs now creates hugefiles more efficiently (with fewer extent tree
+blocks).
+
+Fix a 32/64-bit overflow bug that could cause resize2fs to loop
+forever. (Addresses-Launchpad-Bug: #1321958)
+
+The resize2fs program will now use much less memory when resizing very
+large file systems.
+
+Fix a bug which could cause resize2fs to get confused and produce a
+corrupted file system when shrinking a file system that had been
+previously expanded and converted to use the meta_bg file system
+format, but which no longer needs to use the meta_bg file system
+format any longer.  This typically happened with large (> 16TB) file
+systems.  (Addresses Debian Bug: #756922)
+
+The e4defrag program will now defrag backwards-allocated files.
+
+Fix tune2fs updating UUID's when manipulating file systems with
+external journals (both the file system and journal UUID).
+
+Fix tune2fs so it can remove an external journal for file systems with
+a 1k block size.
+
+Add a new debugfs command, "inode_dump", which prints the inode in hex
+and ASCII format.
+
+The debugfs's "set_inode_field" will now automatically allocate blocks
+for indirect blocks and extent tree blocks.
+
+Fix debugfs's "set_inode_field" so can properly handle
+"block[IND|DIND|TIND]".
+
+The debugfs "rdump" command will now take multiple source arguments.
+
+Fixed a double close(2) bug in "rdump" and "rdump -p".
+
+Fix debugfs's argument parsing for the freefrag command.
+
+Fix filefrag to properly handle using the FIBMAP ioctl (with -B).
+(Addresses Launchpad Bug: #1356496)
+
+Clarified messages that were confusing users in debugfs, e2fsck,
+mke2fs, and resize2fs (Addresses Debian Bugs: #758029, #757543,
+#757544)
+
+Dumpe2fs will now complain if extra arguments are given to it.
+(Addresses Debian Bug: #758074)
+
+Updated/fixed various man pages.  (Addresses-Debian-Bug: #726760)
+
+Update Czech, Dutch, French, Polish, Spanish, Swedish, Ukrainian, and
+Vietnamese translations.
+
+Programmer's Notes
+------------------
+
+The Unix I/O layer will now use pread[64]/pwrite[64] to reduce the
+number of system calls issued.
+
+Fixed profiled build.
+
+The libext2fs library will now more efficiently split an extent tree
+index block when appending to an end of a file.
+
+Fixed free block accounting for 64-bit file systems.
+
+Add a new function ext2s_inode_size_set() which takes care of all of
+the required feature flag modifications.
+
+The regression tests no longer require the presence of the md5sum
+program.
+
+Fix build failure on MIPS platforms on Debian (Addresses Debian Bug:
+#754605)
+
+Fix various Coverity warnings (#1225003, #1229243, #1252003)
+
+
+E2fsprogs 1.42.11 (July 9, 2014)
+================================
+
+Add support so that mke2fs can create hugefiles so that they are
+aligned relative to the beginning of the disk, instead of relative to
+the beginning of the partition, using the mke2fs.conf configuration
+parameter "hugefiles_align_disk".
+
+Fix a bug which causes e2fsck to abort a journal replay on a file
+system with bigalloc enabled.  (Addresses Debian Bug: #744953)
+
+Add sanity checks so that mke2fs will refuse insanely large flex_bg
+counts specified by the -G option.  Insanely large flex_bg sizes can
+result in a file system which can't be unmounted, or with extremely
+pessimal metadata layouts.
+
+The mke2fs program will provide a better metadata layout for
+moderately large (but believable) flex_bg counts, such as 133,072.
+
+The mke2fs program will also check the kernel version number to
+determine whether the lazy_itable_init option is supported, so that
+lazy inode table initialization can be used even if the ext4 is
+compiled as a module which isn't loaded at the time that mke2fs is
+run.
+
+Add description of ext4's mount options to the ext4 section 5 man
+page.
+
+Improve the chattr man page and clean up the chattr usage message.
+
+E2fsck will now automatically fix a last mount time or last write time
+which is in the future in preen mode, instead of aborting the fsck
+check.
+
+Mke2fs will now check the file system revision number requested by the
+command line, and reject it if it is too large.  A file system with an
+unsupported revision number will not be accepted by any of the other
+file system tools, and this command line option is rarely used, so
+let's try to help the user not shoot their own foot off.
+
+The debugfs program can now set the error count and associated
+first_error and last_error fields in the superblock using the
+set_super_value command.
+
+Resize2fs will not try to calculate the minimum size of a file system
+if it contains errors.  Otherwise a very badly corrupted file system
+image can cause the minimum size calculation to loop forever.  Since
+resize2fs will not allow a file system marked as containing errors to
+be resized.  It's pointless to calculate the minimum size, so just
+skip it.
+
+Fixed a typo in one of mke2fs's error message.
+
+If filefrag runs into an error, it will continue processing the rest
+of the files specified on the command line, but then exit with an
+error code.
+
+Filefrag now prints some additional new flags (such as
+FIEMAP_EXTENT_ENCODED), and print unknown flags as hex values.
+
+Fixed support in filefrag for files with > 2**32 blocks on 32-bit
+platforms.
+
+Fixed a file descriptor leak in debugfs when copying files.
+
+Fixed a regression introduced in 1.42.10 which caused mke2fs to fail
+to create file systems larger than 2GB on 32-bit platforms.
+(Addresses Red Hat Bugzilla: #1099892, Debian Bug: #752107)
+
+Add Esperanto and Ukrainian translations, and update Czech, Dutch,
+French, German, Italian, Polish, Swedish, and Vietnamese
+translations.
+
+Fixed various compiler warnings.
+
+
+Programmer's Notes
+------------------
+
+The gcc "-checker" option has been long deprecated, so remove support
+from e2fsprogs.  It was causing a few people to be confused when they
+tried enabling the configure option.
+
+Update to the latest version of the config.status and config.rpath
+files, as well as newer versions of the autoconf files in aclocal.m4.
+Also, move the e2fsprogs-specific macros to acinclude.m4, which allows
+people who want to use autoreconf to do so.
+
+Make the use of strptime() function in debugfs to be more portable to
+fix regression test failures for FreeBSD and MacOS.
+
+A few miscellaneous changes designed to make life easier for
+translators.
+
+Fix the f_quota test and some Makefile dependencies if quota support
+is not enabled.
+
+Fix cross-compilation support, which got broken in 1.42.10.
+(Addresses Debian Bug: #753375)
+
+Delete lib/ext2_types.h on a make clean, and build it as necessary.
+
+Add a debug program used for libext2fs unit tests.
+
+Clean up the tests so that it avoids using GNU-specific behaviour in
+mktemp.  Make sure the temporary files are cleaned up if the tests are
+interrupted.
+
+Add a new ext2fs_close_free() helper function which automatically
+takes care of freeing the ext2_filsys structure even if ext2fs_close()
+returns an error.
+
+
+E2fsprogs 1.42.10 (May 18, 2014)
+================================
+
+Mke2fs now creates file systems in regular files (which is very often
+used when maintaining virtual machine images) without requiring the
+user to use the force option.  In addition, the mke2fs output has been
+made much less verbose and only displays information that users will
+be more likely to find useful by default.
+
+Mke2fs now will ask the user to confirm that they want to continue
+before wiping out a pre-existing file system, partition table, or LVM
+physical volume.
+
+Mke2fs now has the ability to create file systems where all the
+metadata is located at the very beginning of the device.  This can be
+useful for flash devices which have SLC flash at the beginning of the
+disk, for FAT compatibility, for example.  As part of this, mke2fs and
+tune2fs can control the location of the data blocks used by the
+journal inode.  In addition, the new sparse_super2 feature allows for
+even fewer (anywhere from zero to two) backup superblocks.
+
+Mke2fs now uses much less CPU when allocating the blocks used for very
+large file systems.
+
+Mke2fs can now support creating a file system at an offset.  This can
+be useful when creating a disk image for virtual machines (Addresses
+Debian Bug: #497984)
+
+Previously, e2fsck had a number of very serious bugs when checking a
+file system which used the new the quota file system option (where the
+quota inodes were stored in hidden inodes) and the quota inode was
+inconsistent with the actual usage data.  This problem was documented
+in https://ext4.wiki.kernel.org/index.php/Quota.  These problems have
+been fixed in 1.42.10, so the quota should be safe to use with
+e2fsprogs 1.42.10.
+
+Fixed in a bug in resize2fs which could cause shrink operation fail in
+the unlikely situation when the inode table needs to be moved to a
+location before the current location.
+
+Resize2fs now has a much more accurate (and less conservative)
+estimation of how far the file system can be shrunk.  This allows a
+mostly empty filesystem which is a few terabytes, to be shrunk to a
+few megabytes in a single resize2fs -M operation.
+
+E2fsck will now force a full file system check if there are any file
+system inconsistencies detected in the super block.
+
+The filefrag program will now display the shared extent flag, which is
+used by file systems such as btrfs.
+
+If the number of inodes in the file systems is larger than the time
+that file system was created (as measured by the number of seconds
+since January 1, 1970) e2fsck would print a scary (but otherwise
+harmless) warning of file system corruption for each inode in the
+orphan list.  This false positive has been fixed.
+
+The e4defrag program has been fixed so it will no longer refuse with
+filesystem with the 64-bit or the bigalloc feature enabled.
+
+The logsave program will print a much less scary message which could
+lead users to believe something has gone very wrong with e2fsck exits
+with a non-zero exit status (since this is normal after e2fsck has
+automatically fixed a file system corruption during a preen
+operation).   (Addresses Debian Bug: #468821)
+
+When creating a file system which is larger than 16TB, the
+resize_inode option must be disabled -- since the resize_inode simply
+doesn't support reserving metadata block numbers which is larger than
+32 bits.  The mke2fs program does this automatically if the file
+system size is determined automatically.  It will now also do this if
+the file size is specified explicitly.
+
+Fixed bugs associated with resize2fs and shrinking bigalloc file
+systems.
+
+The e2fsck program will no longer try to add a UUID on a mounted file
+system with checksums enabled, since this could leave the file system
+checksums broken.
+
+Tune2fs will allow the removal of an external journal from file system
+which is marked as needing the journal replayed when the force ("-f")
+option is given twice.  (Addresses Debian Bug: #559301)
+
+Tune2fs will no longer support enabling sparse_super if the meta_bg
+file system feature is enabled, since it could result in data loss.
+In practice, all modern file systems have sparse_super is enabled, so
+it's not worth trying to change how tune2fs handles enabling the
+sparse_super feature.
+
+Fixed support for 1k block file systems with the meta_bg feature.
+
+When the superblock is corrupt, e2fsck can't figure out the location
+of the alternate superblock.  Unfortunately, the routine that
+calculates the location of the alternate superblock uses 8193 if it
+can't figure this out, so the message printed by e2fsck always
+suggests using "e2fsck -b 8193".  This message has been fixed to
+suggest both the superblock location of 8193 and and 32768.
+(Addresses Debian Bug: #719185)
+
+The lookback mount detection code that was introduced in 1.42.9 wasn't
+actually compiled in due to an autoconf oops, so it's fixed now in
+1.42.10.  (Addresses Debian Bug: #497984)
+    
+A bug introduced in 1.42.9 would cause debugfs to print two error
+messages if it found an error while parsing a user-supplied block
+number.  This has been fixed in 1.42.10.
+
+Update Czech, Dutch, French, German, Polish, Spanish, Swedish, and
+Vietnamese translations.  (Addresses Debian Bug: #703048)
+
+Updated/fixed various man pages.  (Addresses Debian Bugs: #719189,
+#719184)
+
+Fixed various Debian Packaging Issues.  (Addresses Debian Bug: #718725)
+
+
+Programmer's Notes
+------------------
+
+Fixed a lot of coverity, sparse, gcc -Wall, and clang warnings/nits.
+
+Allow the location of pkg-config files to be specified independent of
+the libdir location via a makefile variable.
+
+Fixed parse-types.sh not to complain when cross-compiling and the
+sizes of types are different between the target architecture and the
+architecture of the build system
+
+Allow the regression test suite to work correctly on systems which do
+not have the "truncate" or "mksawp" programs.
+
+Allow e2fsck to build correctly on systems (such as Android) that do
+not have the signal.h file.
+
+E2fsprogs now has code coverage testing which can be enabled using
+"configure --enable-gcov".
+
+The libe2p.h header file can now be used included by C++ programs.
+
+The profile/config file used by e2fsck and mke2fs will interpret
+numbers with a leading 0 character to mean that they should be
+interpreted as an octal integer.
+
+The extent handling functions in libext2fs have been improved so they
+have proper rollback when there is an error splitting an extent.  Also
+fix a number of bugs when punching holes in files, and fix an
+off-by-one bug when inserting an extent into an empty inode.
+
+The libext2fs library now handles the support of BLOCK_UNINIT by
+clearing the portion of block bitmap when it is loaded, instead of
+when it is used.  This reduces the chances of bugs, and and simplifies
+the code.  It also means that debugfs will properly show that blocks
+in uninitialized block groups as being unused when using the testb
+command.
+
+The e4defrag program will try to use fadvise64 or posix_fadvise64() if
+it is present, which allows 64-bit offsets on 32-bit systems.
+
+
+E2fsprogs 1.42.9 (December 28, 2013)
+====================================
+
+Mke2fs will detect an attempt to create a file system on a loop
+mounted file and complain without the -FF option.  Also fixed mke2fs
+so it allows the creation of a file system on a mounted device with
+two -F options, as documented in the man page, instead of three -F
+options.
+
+Fixed a large number of bugs in resize2fs, e2fsck, debugfs, and
+libext2fs to correctly handle bigalloc and 64-bit file systems.  There
+were many corner cases that had not been noticed in previous uses of
+these file systems, since they are not as common.  Some of the bugs
+could cause file system corruption or data loss, so users of 64-bit or
+bigalloc file systems are strongly urged to upgrade to e2fsprogs
+1.42.9.
+
+The tune2fs program will now not allow changing the uuid on a mounted
+file system which has the uninit_bg feature enabled.  This avoids a
+nasty race where the kernel and tune2fs are both retrying rewrite the
+group descriptors at the same time, with different ideas about what
+the UUID should be.
+
+When e2fsck is rehashing an extent-mapped directory, it's possible
+(although very rare) that an extent block will need to be allocated;
+fix e2fsck to make sure that the block gets marked as used.
+
+Mke2fs will now properly set the LARGE_FILE feature when creating a
+journal >= 2GB --- which can happen when using 64k block size.
+
+Fixed debugfs so that its freei command will correctly handle a request
+to free a range of consecutive inodes.
+
+Fixed 2fsck so it will not erroneously complain that an external journal
+is invalid if it is exactly 2**32 blocks.
+
+Fixed e2fsck so it won't try checking for, and adding, a missing
+lost+found directory when running in read-only mode.
+
+Fixed e2image so that progress information won't get leaked to stdout.
+(Addresses Red Hat Bugzilla: #1327329)
+
+Fixed e2image to avoid some buffer overruns which would cause it to when
+creating a "standard (non-raw, non-qcow2) image file.  Standard
+e2image files are actually very rarely used, so we didn't notice when
+the changes to enable the qcow2 format broke this e2image mode.
+
+Fixed mke2fs so that the extended option "-E resize=NNN" will not turn
+on the resize_inode feature when the meta_bg feature is set, since
+these two features can not be set at the same time.
+
+Fixed tune2fs so that when it disables the quota feature, it updates all
+of the backup superblocks.
+
+Fixed dumpe2fs that would cause it to abort when run using an image file
+when trying to print the journal information (which is not present in
+an e2image created image file).
+
+Fixed a potential integer overflow in e2reefrag.
+(Addresses-Debian-Bug: #718205)
+
+Enhance debugfs so that when copying a sparse file from a native file
+system into the file system image using the "write" command, it will
+create a sparse file into the destination file system.
+
+Enhanced debugfs so it can support a command line which is up to 8k
+long.
+
+E2image will refuse (unless the -f option is specified to force the
+issue) to create a raw or qcow image using a mounted file system,
+unless the -f option is specified to force the issue.
+
+E2image has been optimized for using it to efficiently copy a file
+system by only copying the allocated blocks, by using the options -ra.
+New options (-o and -O) have been added so that a source and
+destination offset can be given.  The -p option will print progress
+information so the user will know how far along the copy is going.
+And finally, the new option -c is useful for updating a file system on
+an SSD, by avoiding unnecessary writes.  E2image can also shift a file
+system image by doing an in place move.
+
+Fix a regression introduced in 1.42.8 which would cause e2fsck to
+erroneously report uninitialized extents past the EOF (as determined by
+i_size) to be invalid.
+
+Fixed resize2fs so under a corner case when an inode has a complex
+extent tree, it will not corrupt an interior node in the extent tree.
+
+Fixed resize2fs which would sometimes corrupt a file system when
+shrinking a file system to a minimum size using resize2fs -M.
+(Addresses Debian Bug: #660793)
+
+Fixed resize2fs so that it will relocate inode table blocks if this
+becomes necessary when shrinking the file system.
+
+Fixed resize2fs and e2fsck so they will not crash when hit a failure
+while operating on a file system with the MMP feature enabled.
+
+Fixed a bug in debugfs which caused it create an invalid inode when
+trying to write a zero-length file.
+
+E2fsck will no longer crash if it tries to delete an invalid
+extent-mapped symlink.
+
+E2fsck will no longer crash if it comes across an directory which is
+larger than 2GB (which is not allowed in valid file systems).
+
+Fixed debugfs's help texts to fully document all options and otherwise
+be more helpful.
+
+Updated/fixed various man pages.  (Addresses Debian Bugs: #586218,
+#669730, #698076)
+
+Fixed various Debian Packaging Issues (#698879, #721365)
+
+
+Programmer's Notes
+------------------
+
+Fix sparse, gcc -Wall and clang nits.
+
+Update config.{guess,sub} to the latest version
+
+Fixed various memory and file descriptor leaks on various error paths,
+as well as some missing error return checks, which were found using
+Coverity.
+
+Run sparse against source files when building e2fsprogs with 'make
+C=1'.  If instead C=2, it configures basic ext2 types for bitwise
+checking with sparse, which can help find the (many many) spots where
+conversion errors are (possibly) happening.
+
+Allow the regression test to be run in chrooted environments where
+/etc/mtab might be missing.
+
+The ext2fs_punch() function, which was introduced in 1.42, was broken
+in many ways, but this was never noticed since it wasn't used for
+anything significant.  Some of the bugs include failing when trying to
+punch a completely sparse file, failing when punching an extent-mapped
+inode when the starting block was at the beginning of the inode, and
+not being able to punch a single block (where start_blk == end_block).
+It also didn't handle being passed an invalid, too-large ending block
+number, and didn't handle properly terminate at the right place when
+operating on an indirect-mapped inode.
+
+Fixed some minor typo's in the error catalog for libext2fs.
+
+Fixed ext2fs_file_set_size2() so that if it truncates an inode by
+setting the file size, to zero the rest of the block to the end of the
+file, so that if an ext4 FUSE driver tries to extended the file, that
+we don't avoid stale data from being returned.
+
+Fixed ext2fs_bmap() to disallow clients from trying to map or set
+logical blocks which are larger than what an extent-mapped or indirect
+block-mapped inode can allow.
+
+If debugfs (or some userspace program using libext2fs) creates a file
+which is larger than 2GB, make sure the large_file feature flag gets
+set.
+
+Fix a bug in ext2fs_link() where if there is multiple empty slots in the
+directory which are large enough, the directory entry could get
+inserted more than once in the directory.
+
+If quota support is disabled (which is the default), make sure that
+all traces of the quota support is removed from usage messages, man
+pages, and tune2fs must not be able to enable the quota file system
+feature.  (Addresses Red Hat Bugzilla: #1010709)
+
+The ext2fs_file_write() now updates i_size on a successful write,
+instead of only updating i_size wen the file is closed via
+ext2fs_file_close().
+
+Added a shell script, populate-extfs.sh which uses debugfs to populate
+an ext2/3/4 file system image from a given directory.  It is similar
+to the genext2fs program, but it supports ext3 and ext4 file system.
+
+Add changes to the libext2fs library to support block group
+descriptors larger than 64 bytes (for future compatibility).
+
+Fixed an off-by-one bug in ext2fs_file_set_size2() so that it will not
+leave an extra block in the file when truncating the file down to
+size.
+
+The html version info pages are now built using makeinfo --html
+instead of the unmaintained and now-obsolete texi2html program.
+
+
+E2fsprogs 1.42.8 (June 20, 2013)
+================================
+
+As a part of mke2fs's option parsing cleanup, the use of the -R option
+will give a warning that it is deprecated (it has been so documented
+since 2005) and -E should be used instead.
+
+Mke2fs will not give warnings about the bigalloc and quota options in
+quiet mode.
+
+If an invalid journal size is given to mke2fs, it will now complain
+and exit sooner.
+
+Debugfs was erroneously giving spurious error messages for certain
+extent_inode subcommands which take arguments (split_node,
+replace_node, and insert_node).  This has been fixed.
+
+Fix the parsing of the 's' (sectors) in parse_num_blocks2, which among
+other programs is used by mke2fs.
+
+Change mke2fs so that it does not set the root directory to the real
+uid/gid of the mke2fs process.  Add the extended option root_owner to
+override this behavior.
+
+Fix resize2fs when shrinking file systems to make sure that bitmap
+blocks aren't left outside the bounds of the shrunken file system.
+This could happen with flex_bg file systems that were grown using
+the old online resizing algorithm.
+
+E2fsck will now detect and repair corrupted extent trees which contain
+invalid extents at the end of the extent tree leaf block.
+
+E2fsck will now longer complain about zero length extended attribute
+values.
+
+Fix a regression introduced in e2fsprogs v1.42 which caused e2image -s
+to crash.
+
+Add safety check so tune2fs will not attempt to set the inode size to
+be larger than the block size.

+
+Use secure_getenv() in preference to __secure_getenv().
+
+Optimize CPU utilization of ext2fs_bg_has_super().
+
+Fix ext2fs_llseek() on 32-bit i386 systems to work correctly when
+SEEK_CUR is used with large files.
+
+The ext2fs_read_inode_full() function will no longer use

+
+Fix build failure with --enable-jbd-debug.
+
+Clean up filtering of outputs for the regression tests by using a

+
+Fix gcc -Wall and clang nits.
+
+
+E2fsprogs 1.42.7 (January 21, 2013)
+===================================
+
+Add warnings to mke2fs, resize2fs, and tune2fs that the bigalloc and
+quota features are still under development.  For more information
+please see:
+    * https://ext4.wiki.kernel.org/index.php/Bigalloc
+    * https://ext4.wiki.kernel.org/index.php/Quota
+
+Add some new options to filefrag from Lustre's patches to e2fsprogs:
+    * add -k option to print extents in kB-sized units (like df -k)
+    * add -b {blocksize} to print extents in blocksize units
+    * add -e option to print extent format, even when FIBMAP is used
+    * add -X option to print extents in hexadecimal format
+
+Fix resize2fs so that it can handle off-line resizes of file systems
+with the flex_bg feature but without a resize_inode (or if we run out
+of reserved gdt blocks).  This also fixes a problem where if the user
+creates a filesystem with a restricted number of reserved gdt blocks,
+an off-line resize which grows the file system could potentially
+result in file system corruption.
+
+Fix a resize2fs bug which could cause it to corrupt bigalloc file
+systems when doing an off-line resize.
+
+Further optimize resize2fs so it doesn't use quite as much CPU when
+resizing very large file systems. 
+
+Fixed 32-bit overflow bugs which could cause resize2fs to fail and
+possibly corrupt the file system while resizing 64-bit file systems.
+
+Fix a bug in mke2fs where parsing "-E resize=NNN" will result in a
+mke2fs crash due to a divide-by-zero if the 64bit file system feature
+is enabled.
+
+Add better error checking to mke2fs to check for invalid parameters
+when creating bigalloc file system.
+
+When creating bigalloc filesystems, the -g option to mke2fs will now
+specify the number of clusters per block group.
+
+Add to debugfs the functionality to corrupt a specific file system
+block via the "zap_block" command.
+
+Add to debugfs the functionality to print out a hex dump of a block in
+the file system via the "block_dump" command.
+
+Add to debugfs the functionality to manipulate the extent tree
+directly via the "extent_open" command.
+
+Fixed debugfs's mknod command so that it updates the block group
+statistics.
+
+Fix e2fsck so it can detect and fix inconsistencies in the interior
+nodes of an inode's extent tree.
+
+Fix a potential memory corruption failure in e2fsck's error path if
+the call to ext2fs_open2() fails.
+
+Fix e2fsck if its logging function is enabled in e2fsck.conf, and the
+resulting file name for the log file is longer than 100 bytes, that it
+properly handles this situation instead of crashing.
+
+E2fsck will now report the amount of memory that it attempted to
+allocate when a memory allocation request fails, to make it easier to
+track down the problem.
+
+Fix mke2fs's handling of the mmp_update_interval option.  (Addresses
+Lustre Bug: LU-1888)
+
+E2image can now include all data blocks in the e2image output file
+when the user specifies the -a option.
+
+If e2fsprogs is compiled without --enable-quota, make sure that
+tune2fs can not turn on the feature for new-style quota support, since
+afterwards, none of the e2fsprogs tools will be willing to touch that
+file system.
+
+Optimize e2fsck's so that it uses much less CPU for large file
+systems.  This can result in significant speedups, especially on
+CPU-constrained systems.  This was primarily done by optimizing
+libext2fs's bitmap functions.  (Addresses Google Bug: #7534813)
+
+Fix debugfs's htree command so that all its messages are sent through
+the pager.
+
+Fixed debugfs's "dump_file" and "cat" functions work correctly
+on file systems whose block size is greater than 8k.
+
+Fix e2freefrag so it works on 64-bit file systems, and so it uses much
+less memory.  (Addresses Google Bug: 7269948)
+
+Update the spd_readdir.c file in the contrib directory to include some
+additions which were made in 2008 that didn't get folded into the
+version which we checked into the e2fsprogs source tree.  These
+enhancements include thread safety, support for readdir64_r(), and
+safe_getenv() support in case spd_readdir.so is used for setuid binaries.
+
+Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
+translations
+
+Add a command to debugfs to create symlinks.
+
+Document the bigalloc feature in the mke2fs man page.  (Addresses
+Debian Bug: #669730)
+
+
+Programmer's Notes
+------------------
+
+Fix gcc -Wall nits.
+
+Fix a spelling typo in the libext2fs texinfo documentation.
+
+Change the output from "make check" so that tools such as emacs's "M-x
+compile" does not mistake the output as containing a compiler error.
+
+Export two new functions from libext2fs: ext2fs_extent_node_split()
+and ext2fs_extent_goto2().
+
+The ext2fs_extents_fix_parents() was fixed so it does not modify the
+location of the extent handle if its current location is at an
+interior node, rather than a leaf node of an inode's extent tree.
+
+Add a regression test to assure that e2fsck can correctly fix an
+inconsistent interior node in an inode's extent tree.
+
+The ext2fs_{mark,unmark,test}_block_bitmap_range2() functions now
+correctly support bigalloc file systems which use store block usage
+information in units of clusters.
+
+Fixed the help text in the configure script for --enable-quota.
+
+The m68k-specific bitops code has been removed since they were
+incorrectly treating bit numbers with the high bit set as signed
+integers.  Furthermore, modern compilers do a good enough job
+optimizing the generic code there is no point in having the m68k
+specific asm statements.
+
+Fixed how we link the test programs so they always use the static
+libraries, so that we test using the libraries which we have just
+built.
+
+Update config.guess and config.sub to the latest versions from the GNU
+project.
+
+Fixed the com_err.texinfo file so that it can produce a valid
+postscript/pdf printed output.
+
+Add a regression test which checks debugfs's ability to create
+symlinks, named FIFO's, and device nodes.
+
+Add a function ext2fs_symlink(), which creates symlinks to the
+libext2fs library.
+
+Add debugging code so we can test old kernel interfaces for online
+resize to resize2fs.  This backwards compatibility checking is keyed
+off of the RESIZE2FS_KERNEL_VERSION, which is designed to allow us to
+test the functionality of the kernel's older resize ioctls without
+needing to install an old version of resize2fs, and to also test a
+modern resize2fs's ability to work with older kernels without having
+to install an older version of the kernel.
+
+
+E2fsprogs 1.42.6 (September 21, 2012)
+=====================================
+
+When mke2fs creates file systems with lazy itable initialization, the
+progress updates for writing the inode table happens so quickly that
+on a serial console, the time to write the progress updates can be the
+bottleneck.  So mke2fs will now only update its progress indicators
+once a second.
+
+Resize2fs will skip initializing the inode tables if the kernel
+supports lazy_itable_init, which speeds up growing off-line growth of
+uninit_bg file systems significantly.  Resize2fs will now also
+correctly set the itable_unused field in the block group descriptor to
+speed up the first e2fsck after the file system is grown.
+
+Resize2fs has been fixed so that on-line resizing of meta_bg file
+systems work correctly.  This is needed to grow file system which are
+larger than 16T.
+
+Resize2fs will now correctly handle resizing file systems to 16TB on
+32-bit file systems when "16TB" is specified on the command line.
+
+Fix mke2fs so that it will be careful to set the reserved blocks ratio
+larger than 50%; this can happen when creating small file systems and
+when the last block group is dropped because there are not enough
+blocks to support the metadata blocks in the last block group.
+
+Fixed spelling mistake in debugfs's help message.
+
+Fixed a potential seg fault in e2fsck when there is an I/O error while
+reading the superblock.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #677497)
+
+Updated/fixed various man pages.  (Addresses Sourceforge Bug:
+#3559210)
+
+Programmer's Notes
+------------------
+
+The configure option --enable-relative-symlink was broken so that it
+needed to be --enable-symlink-relative-symlinks.  We will support both
+for at least two years, but then the wrong configure option will be
+removed.
+
+Fixed a regression introduced in 1.42.5 so the link order for
+e2fsprogs' libraries will be correct for both static and shared
+linking.  (Addresses Sourceforge Bug: #3554345)
+
+Add support for e2fsprogs to be compiled using clang/LLVM.
+
+Fix portability problems on non-Linux systems: avoid compile failures
+on systems that don't have malloc.h
+
+Fix f_mmp regression test suite so that debugfs gets killed if the
+test is interrupted.
+
+
+
+E2fsprogs 1.42.5 (July 29, 2012)
+================================
+
+Fixed a bug with mke2fs where if there is only 8 inodes per block
+group, the calculation of the number of uninitialized inodes in the
+first block group would go negative.  This resulted in "mke2fs -N 256
+-t ext4 /tmp/foo.img 256m" trying to write so many blocks that /tmp
+would run out of space.  (Addresses Sourceforge Bug: #3528892)
+
+Fixed a bug in how e2fsck would uniquify directory entry names.
+(AddressesSourceforge Bug: #3540545)
+
+Previously, e2fsck would only allow a mounted file system to be
+checked if it was the root file system and it was mounted read-only.
+Now it will allow any file system mounted read-only to be checked if
+the -f option is specified.  This makes it easier to test how e2fsck
+handles checking file systems which are mounted without having to test
+on the root file system.
+
+Fixed a problem if e2fsck where if the root file system is mounted
+read-only, e2fsck would not clear an error indication in the journal
+superblock.  Combined with a kernel bug, this would cause the e2fsck
+to check the file system after every single boot.
+
+The e4defrag program can now handle device symlinks, such as
+/dev/mapper/testvg-testlv, instead of insisting on a less
+human-friendly name such as /dev/dm-2.  (Addresses Red Hat Bugzilla:
+#707209)
+
+Fixed filefrag so it will not crash with a segfault on files from a
+virtual file system such as /proc.  (e.g., "filefrag
+/proc/partitions")
+
+Fixed filefrag so that it correctly reports the number of extents.
+(Addresses Red Hat Bugzilla: #840848)
+
+Fixed a file descriptor leak in logsave which could cause it to hang.
+(Addresses Debian Bug: #682592)
+
+Fixed e2fsck so that the file system is marked as containing an error
+if the user chooses not to fix the quota usage information.
+
+Fixed tune2fs so that it correctly removes the quota feature when the
+last quota inode is removed.
+
+Fix tune2fs so that after removing a quota inode, the block bitmap is
+updated; otherwise, e2fsck would complain after running 'tune2fs -O
+^quota <dev>'.
+
+Fix tune2fs so that when converting a file system from using legacy
+quota files to the new quota file system feature with hidden quota
+files, the accounting for these files is handled correctly so that
+e2fsck doesn't complain.
+
+Improved e2fsck's verbose reporting statistics, and allow the more
+verbose reporting to be enabled via /etc/e2fsck.conf.
+
+Fixed various Debian Packaging Issues (Addresses Debian Bug #678395)
+
+Updated/fixed various man pages.  (Addresses Debian Bugs: #680114)
+
+
+Programmer's Notes
+------------------
+
+Fixed portability problems on other operating systems (e.g., Hurd and
+FreeBsd) caused by the attempted inclusion of <sys/quota.h>.
+
+Make sure that shared libraries link with the shared libraries built
+in the build tree, instead of the system provided libraries.
+Previously, libraries and executables were linked with the system
+libraries if present, and possibly using static archives instead of
+shared libraries.  This was also problematic since if libext2fs.so is
+linked with a static libcom_err.a from system, the build system would
+attempt to link without -lpthread.  (Addresses Sourceforge Bug:
+#3542572)
+
+
+E2fsprogs 1.42.4 (June 12, 2012)
+================================
+
+Fixed more 64-bit block number bugs (which could end up corrupting
+file systems!) in e2fsck, debugfs, and libext2fs.
+
+Fixed e2fsck's handling of the journal's s_errno field.  E2fsck was
+not properly propagating the journal's s_errno field to the superblock
+field; it was not checking this field if the journal had already been
+replayed, and if the journal *was* being replayed, the "error bit"
+wasn't getting flushed out to disk.
+
+Fixed a false positive complaint by e2fsck if all of the extents in
+the last extent tree block are uninitialized and located after the end
+of the file as defined by i_size.
+
+The dumpe2fs will now display the journal's s_errno field if it is
+non-zero, and it will also display the journal's 64-bit feature flag
+if present.
+
+Fix e2fsck so that it always opens the device file in exclusive mode
+when it might need to modify the file system, and never if the -n
+option is specified.  (Previously, there were a few corner cases where
+it might get things wrong in either direction.)
+
+E2fsck now correctly truncates or deallocates extent-mapped inodes on
+the orphan list.  The root cause was a bug in libext2fs's block
+iterator which could end up skipping an extent when the last block in
+an extent is removed, causing the current extent to be removed from
+the extent tree.
+
+E2fsck now correctly sets the global free block and inode counts when
+truncating or removing inodes on the orphan list in preen mode.
+Previously, it would leave these values would be set incorrectly,
+which is largely a cosmetic issue since the kernel no longer pays
+attention to those fields, but it can cause spurious complaints in
+subsequent e2fsck runs.
+
+Fix i_blocks accounting when the libext2fs library needs to add or
+remove an extent tree block  on bigalloc file systems.
+
+The lsattr and chattr programs now support the No_COW flag for the
+benefit of btrfs.
+
+Debugfs now interprets date strings of the form @ddd as ddd seconds
+after the beginning of the epoch.  This is handy when setting an inode
+number into the d_time field when debugging orphan list handling.
+
+Fix a precedence bug with built-in quota support which might result in
+e2fsck paying attention to the quota inode field even if the built-in
+quota feature flag is not set.  Fortunately, in practice that
+superblock field should be zero for non-built-in quota file systems,
+so it's unlikely this bug would have caused problems.
+
+Updated/fixed various man pages.  (Addresses Debian Bugs: #674453,
+#674694)
+
+Programmer's Notes
+------------------
+
+The regression test suite can now run the integration tests in the
+tests directory in parallel, via "make -jN check".
+
+Add new test, f_zero_extent_length which tests e2fsck's handling of
+the case where all of the extents in the last extent tree block are
+uninitialized extents after i_size.
+
+Add a new test, f_jnl_errno, which checks handling of an error
+indication set in the journal superblock.
+
+Fix the test f_jnl_64bit so that it properly checks e2fsck's handling
+of a 64-bit journal.
+
+Add two tests, f_orphan_indirect_inode and f_orphan_extent_inode which
+tests e2fsck's handling of orphan inodes in preen mode, and truncation
+of extent inodes on the orphan list.
+
+Fixed more OS X portability issues.
+
+
+E2fsprogs 1.42.3 (May 14, 2012)
+===============================
+
+Fix a bug in the Unix I/O manager which could cause corruption of file
+systems with more than 16TB when e2fsprogs is compiled in 32-bit mode
+(i.e., when unsigned long is 32-bits).  Also fix a bug which caused
+dumpe2fs to incorrectly display block numbers > 32-bits.
+
+Improve the support for integrated quota files (where quota is a first
+class supported feature using hidden files in the ext4 file system).
+Previously the quota file was getting rewritten even when it was not
+necessary, and e2fsck would erroneously try to hide quota files which
+were already hidden.
+
+Quiet complaints in e2fsck when the total free blocks or inodes are
+incorrect in the superblock after an system crash, since we don't
+update nor depend on the superblock summaries at each commit boundary.
+
+Fixed a regression introduced in 1.42.2 which would cause applications
+outside of e2fsprogs which did not pass the EXT2_FLAG_64BIT (and so
+would were still using the legacy 32-bit bitmaps) to crash.  This was
+due to missing 32-bit compat code in side the function
+ext2fs_find_first_zero_generic_bmap().  (Addresses Red Hat Bugzilla:
+#808421)
+    
+Fix a bug which would cause mke2fs to fail creating the journal if
+/etc/mtab and /proc/mounts are missing.  (Addresses Sourceforge Bug:
+#3509398)
+    
+Updated/fixed various man pages.
+
+Update Czech, Dutch, French, German, Polish, Swedish, and Vietnamese
+translations
+
+Fixed various Debian Packaging issues.
+
+
+Programmer's Notes
+------------------
+
+Change the nonsensically wrong types in the function signature of the
+inline function ext2fs_find_first_zero_block_bitmap2().  This was
+caused by a cut and paste error; fortunately no code in e2fsprogs used
+this inline function, and there are any users of this functions
+outside of e2fsprogs.
+
+Add support for systems which have valloc(), but which do have
+posix_memalign() nor memalign() (such as MacOS 10.5).
+
+Refactor and clean up the allocation of aligned buffers for Direct I/O
+support.  Previously some allocations were requesting a greater
+alignment factor that what was strictly necessary.  Also optimize
+reading and writing bitmaps using Direct I/O when the size of the
+bitmap did not fully cover the file system blocksize.
+
+Reserve the codepoints for the INCOMPAT features LARGEDATA and
+INLINEDATA.
+
+Improved the regression test suite by adding some new integration
+tests (f_jnl_32bit, f_jnl_64bit) which detect breakage of the on-disk
+jbd2 format, as well as f_eofblocks which tests the new handling of
+uninitialized and initialized blocks beyond i_size.  Also add a new
+unit test which verifies 32-bit bitmaps support and the new
+find_first_zero primitives.
+
+Add a few dependencies to fix parallel (make -j) builds.
+
+Removed bash'isms which were breaking the regression test suite on
+systems where /bin/sh is not bash.
+
+The config.guess and config.sub have been updated to the 2012-02-10
+version.
+    
+Fix a portability problem caused by assuming the present of mntent.h
+means that setmntent() exists.  Instead, explicitly test for this in
+the configure script.
+
+If the sys/signal.h header file does not exist, don't try to include
+it, since it's not available on all systems.
+
+Add support for systems that do not support getpwuid_r()
+    
+The configure script now supports a new option,
+--enable-relative-symlinks, which will install relative symlinks for
+the ELF shared library files.  (Addresses Sourceforge Bug: #3520767).
+    
+When building BSD shared libraries make sure the LDFLAGS variable is
+passed to the linker.  Fixing this allows, for example, e2fsprogs to
+be built in 32-bit mode on Mac OS X Lion (Addresses Sourceforge Bug:
+#3517272)
+    
+Fix gcc -Wall nitpicks
+
+
+E2fsprogs 1.42.2 (March 27, 2012)
+=================================
+
+The resize2fs program uses much less CPU and is much faster for very
+large file systems.  (Addresses Debian Bug: #663237)
+
+The seti and freei commands in debugfs can now take an optional length
+argument to set and clear a contiguous range of inodes.
+
+E2fsck will now make explicit checks for the EOFBLOCKS_FL, since we
+plan to remove support for it from the kernel file system driver.  It
+really wasn't very useful and was causing more problems than it
+solves.  Since e2fsck will complain if inodes that should have
+EOFBLOCKS_FL do not have the flag set, we are going to remove this
+check from e2fsprogs first, and then only remove the flag from the
+kernel much later.
+
+The mke2fs program can now use direct I/O via "mke2fs -D".  This will
+slow down the mke2fs, but it makes it more polite on a loaded server
+by limiting the amount of memory that gets dirtied by mke2fs when it
+is using buffered I/O.
+
+E2fsck was needlessly closing and re-opening the file system as a side
+effect of adding Multiple Mount Protection (MMP).  This isn't
+necessary for non-MMP file systems, so drop it.
+
+Print errors returned by ext2fs_open2() and ext2fs_check_desc() so we
+can more easily diagnose memory allocation failures caused by
+insufficient memory.  E2fsck will now abort if there are memory
+allocation failures when the file system is initially opened and
+during the block group descriptor checks.  (Addresses Google Bug:
+#6208183)
+
+If there are incorrect block group checks, e2fsck will now report the
+incorrect and corrected checksum values.
+
+The e2fsck program can now write log files containing the details of
+the problems that were found and fixed directly, via configuration
+parameters in /etc/e2fsck.conf.
+
+Added the ability to limit the number of messages reported by e2fsck
+for a given problem type.  This avoids a potential bottleneck if there
+is a serial console which can cause a boot sequence to take a long
+time if e2fsck needs to report many, many file system errors.
+
+The dumpe2fs, debugfs, and tune2fs now use rbtree bitmaps, which cause
+them to use much less memory for large file systems.
+
+The dumpe2fs program will now print the expected block group checksum
+if it is incorrect.  This helps to diagnose problems caused by
+incorrect block group checksums.
+
+E2fsck now checks for extents with a zero length, since the kernel
+will oops if it comes across such a corrupted data structure.  (See
+https://bugzilla.kernel.org/show_bug.cgi?id=42859)
+
+E2fsck has a number of bugs relating to discard that have been fixed.
+(1) Fixed a bug which could cause e2fsck to discard portions of the
+inode table which were actually in use.  (2) E2fsck will now avoid
+using discard if the block device doesn't zero data on discard, since
+otherwise this could cause problems if the file system gets corrupted
+in the future.  (3) E2fsck will now avoid using discard when it is run
+in read-only mode.  (4) Fixed a bug which caused e2fsck to not issue
+discards in the last block group.
+
+E2fsck's CPU utilization in pass 5 has been optimized, which will
+speed up e2fsck slightly.
+
+E2image will now skip copying uninitialized bitmap and inode table
+blocks.
+
+Fixed mke2fs -S so it does not corrupt the first block group's
+information.
+
+E2fsck will now check the new sysfs interface to determine if we are
+using the battery or AC mains.  (Addresses SourceForge Bug: #3439277)

+
+Fixed the debian rules file so that the calls to dpkg-buildflags works
+when the shell is dash.
+
+The debian package build now uses V=1 so that there is more
+information about potential build failures in debian build logs.
+
+If the uninit flags get cleared by functions such as
+ext2fs_new_inode() or ext2fs_new_block2(), we now make sure the
+superblock is marked dirty and the block group descriptor checksum is
+updated if necessary.
+
+The debian rules file will now try to load debian/rules.custom of it
+exists.  This file can skip various builds for speed reasons if there
+is no need for the e2fsck-static or udeb packages.  Available
+customizations in the rules file includes SKIP_STATIC=yes,
+SKIP_BF=yes, and SKIP_DIETLIBC=yes.
+
+In addition, if the file misc/mke2fs.conf.custom.in exists in the
+source tree, it will be used instead of the standard misc.conf file in
+the upstream sources.  This makes it easier for Debian-derived systems
+to distribute a custom mke2fs.conf file without having to worry about
+merge issues if future versions of e2fsprogs makes changes in the
+upstream default version of mke2fs.conf.
+
+
+E2fsprogs 1.42.1 (February 17, 2012)
+===================================
+
+The mke2fs and e2fsck now use significantly less memory when creating
+or checking very large file systems.  This was enabled by adding
+extent-based bitmaps which are stored using a red-block tree, since
+block and inode allocations tend to be contiguous.
+
+The command mke2fs -S is used as a last ditch recovery command to
+write new superblock and block group descriptors, but _not_ to destroy
+the inode table in hopes of recovering from a badly corrupted file
+system.  So if the uninit_bg feature is enabled, mke2fs -S will now
+set the unused inodes count field to zero.  Otherwise, e2fsck -fy
+after using mke2fs -S would leave the file system completely empty.
+
+Since mke2fs recognizes mke3fs in argv[0] to mean "mkfs.ext3", also
+honor "mke4fs" to work the same as "mke2fs.ext4", since RHEL5 has
+installed an mke2fs binary using that name.
+
+The usage and help messages for the -G, -t and -T options in mke2fs
+have been fixed.
+
+If e2fsck needs to use the backup group descriptors, the
+ext2fs_open2() function clears the UNINIT bits to ensure all of the
+inodes in the file systems get scanned.  However, the code which reset
+the UNINIT flags did not also recalculate the checksum, which produced
+many spurious (and scary) e2fsck messages.  This has been fixed by
+resetting checksums when the UNINIT bits are cleared.
+
+Relax a check in e2fsck which required that the block bitmap to be
+initialized when the inode bitmap is in use.  This will allow us to
+eventually eliminate code from the kernel which forcibly initialized
+the block bitmap when the inode bitmap is first used, requiring an
+extra journal credit and disk write.  (Addresses Google Bug: #5944440)
+    
+Make sure rdebugfs (which may be installed setuid or setgid disk) does
+not honor environment variables if euid != uid or egid != gid.
+
+Debugfs's ncheck command has been optimized and now is much more
+robust with faced with corrupted file systems.  The ncheck command
+also now has a -c option which will verify the file type information
+in the directory entry to see if matches the inode's mode bits.  This
+is extremely useful when trying to use debugsfs to determine which
+parts of the file system metadata can be trusted.
+
+E2image will try to use ftruncate64() to set the i_size for raw
+images, instead of writing a single null byte.  This avoid allocating
+an extra block to the raw image, for those file systems and/or
+operating systems that support this.  (Linux does.)  In addition, fix
+a logic bug that caused the file to not be properly extended if the
+size of the last hole was exactly an multiple of a megabyte.
+
+Fixed a bug in resize2fs where for 1k and 2k file systems, where
+s_first_data_block is non-zero, this wasn't taken into account when
+calculate the minimum file system size for use with the -M option.
+
+Fixed the badblocks program to honor the -s flag when in read-only -t
+mode.  (Addresses Debian Bug #646629)
+
+Update Czech, Dutch, French, Polish, and Swedish translations from the
+Translation Project.
+
+Fixed various Debian Packaging issues so that dpkg-buildflags is used
+if present, which allows e2fsprogs to be built with security hardening
+flags.  (Addresses Debian Bugs: #654457)
+
+Programmer's Notes
+------------------
+
+Fix a bug in ext2fs_clear_generic_bmap() when used for 32-bit bitmaps.
+This was only an issue for programs compiled against e2fsprogs 1.41
+that manipulate bitmaps directly.  (Addresses Sourceforge Bugs:
+#3451486)
+
+The libext2fs library now uses sysconf() to fetch the page size, instead
+of the deprecated getpagesize().
+
+The ext2fs_get_pathname() function will return a partial path if an a
+directory in the path is not a directory, displaying it as an inode
+number in angle brackets instead of giving up and displaying an error.
+This is much more helpful when a user is trying to debug a corrupted
+file system.
+
+Codepoints for the RO_COMPAT_REPLICA feature has been reserved.
+
+Added a new library function, ext2fs_file_get_inode_num(), for use by
+fuse2fs.
+
+Fixed a bug in ext2fs_file_set_size2() so that when it is truncating a
+file, it actually works.
+
+The block iterator now properly honors the BLOCK_ABORT flag for
+extent-based flags.  Previously, it didn't, which generally made code
+be less efficient, but it could cause bugs in ext2fs_link(), for
+example, by causing it to insert multiple directory entries.
+
+Fixed an (harmless other than causing a compiler warning) use of an
+uninitialized variable in e2fsck's MMP code.
+
+
+E2fsprogs 1.42 (November 29, 2011)
+==================================
+
+This release of e2fsprogs has support for file systems > 16TB.  Online
+resize requires kernel support which will hopefully be in Linux
+version 3.2.  Offline support is not yet available for > 16TB file
+systems, but will be coming.
+
+This release of e2fsprogs has support for clustered allocation.  This
+reduces the number of block (now cluster) bitmaps by allocating and
+deallocating space in contiguous power-of-2 collections of blocks,
+which are called clustered.  This is a file system level feature,
+called 'bigalloc', which must be enabled when the file system is
+initially formatted.  It is not backwards compatible with older
+kernels.
+
+Added support for the Multi-Mount Protection (MMP) feature.
+
+E2fsck more efficiently uses scratch files for really big file
+systems.  (This is a feature that has to be turned on explicitly; see
+[scratch_files] in the e2fsck.conf man page.)
+
+Fix a bug in e2fsck where if the free blocks and inodes counts are
+incorrect, e2fsck would fix them without printing an error message.
+This would cause a "*** FILE SYSTEM WAS MODIFIED ***" message without
+any explanation of what was fixed.
+
+E2fsck will no longer attempt to clone an extended attribute block in
+pass1b handling if the file system does not support extended
+attributes.
+
+E2fsck will be more careful accidentally asking the user to continue
+if the file system is mounted, so that an escape sequence won't cause
+a false positive.  (Addresses Debian Bug: #619859)
+
+E2fsck now uses less cpu time in pass 5 when large portions of the
+bitmaps are uninitialized.
+
+E2fsck will no longer segfault when a corrupted file system has a bad
+extent, and removing it leads to a block needing to be deallocated.
+(Addresses SourceForge Bug: #2971800)
+
+E2fsck will catch termination signals (segfaults, bus errors, sigfpe)
+and print debugging information to make it easier to find potential
+problems.
+
+E2fsck will check to see if the bad block inode looks insane, and will
+skip trying to use if it certain fields which should be zero look
+non-zero.  This is to avoid a corrupted bad block inode causing e2fsck
+to get confused and do more harm than good.
+
+If e2fsck modifies certain superblock fields which the kernel doesn't
+look at, it will now mark the superblock as dirty without marking the
+file system as changed.  This avoids signaling the init scripts that
+a reboot is necessary, since the kernel isn't going to look at those
+fields, so it won't care if they have been changed.
+
+Fixed a bug in the libext2fs library (in the binary search routine of
+the icount abstraction) that could (very, very rarely) cause e2fsck to
+die in the middle of pass 1 or pass 2 processing.
+
+E2fsck will not try to do a discard operation if the -n option was
+specified on the command line.
+
+E2fsck now supports an extended "discard" option which will cause
+e2fsck to attempt discard all unused blocks after a full, successful
+file system check.
+
+E2fsck will check for the bad block inode to make sure it looks sane
+before trusting it, to avoid causing more harm than good to the file
+system.
+
+E2fsck now returns additional status bits in its exit code if it
+aborts early in the e2fsck run.
+
+E2fsck now correctly calculates the maximum file size in the case of
+the huge_file file system feature enabled without extents.
+
+The mke2fs and e2fsck programs now tries to use the punch hole command
+as a "discard" when operating on normal files.
+
+The e2image program now supports the qcow2 format, which is a more
+efficient way of capturing file system dumps.
+
+Mke2fs now supports the [devices] stanza in mke2fs.conf which allows
+per-device defaults to be specified in the configuration file.
+
+Mke2fs now supports the reserved_ratio relation in the [defaults] and
+[fs_types] section in mke2fs.conf.
+
+Mke2fs now creates extent-mapped directories for the root and
+lost+found directories.
+
+Mke2fs will skip zero'ing the journal if the extended option
+"lazy_journal_init" is specified.  This can save a lot of time, but it
+does add a small amount of risk if the system crashes before the
+journal is overwritten entirely once.  It is especially useful for
+testing.
+
+Mke2fs will now create file systems that enable user namespace
+extended attributes and with time- and mount count-based file
+system checks disabled.
+
+Mke2fs will not set a stride or strip size of one block based on block
+device attributes obtained from sysfs.
+
+Mke2fs now displays a progress report during the discard process.
+
+Mke2fs now handles extreme file system parameters correctly which
+previously caused the inodes per group to drop below 8, leading to a
+segfault.  (The inodes per group must be a multiple of 8, but the code
+didn't correctly deal with an inodes per group count less than 8.)
+
+Mke2fs and tune2fs previously would give an error if the user tried
+setting the stride and stripe-width parameters to zero; but this is
+necessary to disable the stride and stripe-width settings.  So allow
+setting these superblock fields to zero.  (Addresses Google Bug:
+#4988557)
+
+Mke2fs now gives a warning if the auto-detected block size exceeds the
+system's page size.
+
+If the enable_periodic_fsck option is false in /etc/mke2fs.conf (which
+is the default), mke2fs will now set the s_max_mnt_count superblock
+field to -1, instead of 0.  Kernels older then 3.0 will print a
+spurious message on each mount then they see a s_max_mnt_count set to
+0, which will annoy users.  (Addresses Debian Bug: #632637)
+    
+The default mke2fs.conf now has entries for "big" and "huge", which
+are needed for very big file systems.
+
+The resize2fs program now has support for a new online resize ioctl
+that can support file systems > 16TB, once it arrives in v3.x kernels.
+
+Fixed bug which caused resize2fs to fail when shrinking an empty file
+system down to its minimal size.  (Addresses Sourceforge Bug #3404051)
+
+Fixed tune2fs's mount options parsing.  (Addresses Debian Bug: #641667)
+
+Allow tune2fs to remove external journals if the device can not be
+found.
+
+Debugfs's icheck will now correctly find inodes which use the
+searched-for block as an extended attribute block.
+
+Debugfs now has a new "punch" command which remove blocks from the
+middle of an inode.
+
+Debugfs now has a new "e2freefrag" command which analyzes the free
+space fragmentation of the file system, using the same code as the
+e2freefrag program.
+
+Debugfs now has a "filefrag" command which displays information about
+a file's fragmentation.
+
+Add support to build a metadata-only, read-only, stripped-down version
+of debugfs called rdebugfs.
+
+Fixed a potential stack overrun bug in debugfs.
+
+The badblocks program now correctly recovers from I/O errors when
+direct I/O is being used.  The badblocks command now also supports a
+-B option which forces the use of buffered I/O, and the -v option will
+provide a more detailed breakdown of read, write, and failed
+comparison errors.
+
+Added e4defrag tool which uses the EXT4_IOC_MOVE_EXT ioctl.
+
+Added support for journals larger than 2GB.
+
+Support using both hard links and symlinks when installing e2fsprogs.
+
+Add overflow checking to tune2fs -i's fsck interval, which must fit in
+a 32-bit field.
+
+The debugfs command now has a new 'blocks' command which prints out
+data blocks of a particular inode in a format which is useful for
+scripting.
+
+Filefrag will report 0 extents correctly in verbose mode.  (Addresses
+RedHat Bugzilla: #653234)
+
+Filefrag has been fixed so its -v report prints the correct expected
+block number (previously there had been an off-by-one error).  In
+addition, it will now display the number of contiguous extents when -v
+is not specified.  This makes it consistent with the number of extents
+printed when the -v option was specified.  In addition, the number of
+contiguous extents is far more interesting/useful than the number of
+physical extents for very large files.  (Addresses Debian Bug:
+#631498, #644792)
+    
+Logsave's usage message has been fixed.  (Addresses Debian Bug:
+#619788)
+
+Avoid an infinite loop in ext2fs_find_block_device() if there are
+symlink loops in /dev caused by a buggy udev.
+
+Added a useful "fallocate" program to the contrib directory.
+
+Fixed an ABI compatibility problem in libext2fs which broke the dump
+program.  Also added back some macros which dump needed so it could
+compile against the latest version of ext2_fs.h (Addresses Debian Bug:
+#636418)
+
+Fixed parsing of MNTOPT_ options for tune2fs and debugfs (Addresses
+Debian Bug: #641667)
+
+Added internationalization support for libcom_err error table strings.
+
+Fixed various spelling mistakes found in various output strings found
+by I18N translators.
+
+Update translations: French, Chinese, Germany, Indonesian, Swedish,
+Vietnamese, Polish, Dutch, Czech.  (Addresses Debian Bugs: #520985,
+#620659)
+
+Fixed various Debian Packaging issues.  (Addresses Debian Bugs:
+#614662, #632169, #641838, #627535, #629355)
+
+Updated/clarified man pages.  (Addresses Debian Bugs: #639411,
+#642193, #634883)
+
+Programmer's Notes
+------------------
+
+Initial support for quota as an integrated feature, where the quota
+files are hidden system files that are automatically maintained by
+e2fsck is present, although disabled by default.  It must be enabled
+by using the configure option --enable-quota.
+
+Reserved the on-disk fields for the metadata checksum and snapshot
+features, which are currently in development.
+
+The ext2fs library now has the new functions ext2fs_punch(),
+ext2fs_get_memzero() and ext2fs_file_get_inode().
+
+The ext2fs library now has support for calculating the crc32c checksum
+(via the new functions ext2fs_crc32c_be and ext2fs_crc32c_le).
+
+The I/O manager now supports the discard operation.
+
+Reserved file system code points for new 1st class quota feature.
+
+Shortened the compilation lines by moving the autoconf defines to
+a config.h header file.
+
+Fixed a potential free of an uninitialized pointer in
+ext2fs_update_bb_inode().
+
+Fixed miscellaneous gcc -Wall and coverity warnings.
+
+Fixed portability issues for Mac OS X, Hurd, and FreeBSD.
+
+Fixed a build failure when OMIT_COM_ERR is defined.
+
+Improved error checking and fixed memory leaks caused by error return
+paths.
+
+Add ext2fs_flush2() and ext2fs_close2() which takes a flag to allow
+the fsync() to be skipped.
+
+Added a test for extent-mapped journals by mke2fs and tune2fs.
+
+Added a test for creating a large (over 4GB) journal using mke2fs.
+
+Added a test to make sure the inode size remains constant.
+
+The regression test script now prints the list of which tests failed.
+
+The regression test system now uses /tmp for its scratch files, which
+is often a tmpfs mounted file system and hence much faster.
+
+The i_e2image test was fixed so it works with valgrind.
+
+Tests that rely on debugfs are now skipped if debugfs wasn't built.
+
+Fixed the dependencies for "make check" so all required dependencies
+are built before running the regression tests.
+
+A link to com_err.h is installed in $(includedir) during a "make install".
+
+The po/*.gmo files are automatically rebuilt if they are missing or
+out of date.  This helps out Debian packaging.
+
+Allow ext2fs_get_memalign() to compile on systems that don't have
+posix_memalign().
+
+Fixed a namespace leak in libext2fs (tdb_null).
+
