-Changes in version 1.10:
+Changes in version 1.11:
 
-File specified with option "-o" is now created with write permission for
-all if umask allows it, and deleted if lzip is interrupted by the user.
+The option "-0", which produces a compression speed and ratio comparable
+to those of "gzip -9", has been added to lzip.
 
-Regular files are now open in binary mode in non-POSIX platforms
-defining the O_BINARY macro.
+Match length limit set by options -1 to -8 has been reduced to extend
+range of use towards gzip. Lower numbers now compress less but faster.
+(-1 now takes 43% less time for only 20% larger compressed size).
 
-Dictionary size for options -2, -3, -4 and -8 has been changed to
-improve linearity of compressed sizes.
+(Note that the bidimensional parameter space of LZMA can't be mapped to
+a linear scale optimal for all files. If your files are large, very
+repetitive, etc, you may need to use the --match-length and
+--dictionary-size options directly to achieve optimal performance).
 
-Compiler warnings produced by over-optimization (-O3) have been fixed.
+Compression of option -9 has been slightly increased.
+
+The option "--merge", which tries to produce a correct file merging the
+good parts of two or more damaged copies, has been added to lziprecover.
+
+(To give you an idea of --merge's possibilities, when merging two copies
+each of them with one damaged area affecting 1 percent of the copy, the
+probability of obtaining a correct file is about 98 percent. With three
+such copies the probability rises to 99.97 percent. For large files with
+small errors, the probability approaches 100 percent even with only two
+copies).
+
+The option "--repair", which repairs any 1-byte error in the lzma stream
+of lzip files, has been added to lziprecover.
+
+Decompressor has been modified to detect file errors earlier, improving
+efficiency of lziprecover's new repair capability.
+
+The option "--force", which forces overwriting of existing output files,
+has been added to lziprecover.
+
+The option "--output", which sets the name of the output file, has been
+added to lziprecover.
+
+The option "--split", which selects the until now only operation of
+splitting multimember files, has been added to lziprecover.
+
+Lziprecover now needs the operation to be specified. Else it warns the
+user and does nothing.
+
+A warning about fchown's return value being ignored has been fixed.
+
+"lzip -tvvvv" now also shows file compression ratio.
+
+Some new examples have been added to the manual.
