-Changes in version 1.8:
+Changes in version 1.9:
 
-A buffer overflow has been fixed in zcat which happened sometimes when
-the '-v, --show-nonprinting' option was used (or indirectly enabled).
-A canary byte has been added to the output buffer to prevent the buffer
-overflow from happening again.
+zcmp anf zdiff now meet the POSIX requirement for cmp and diff that the
+standard input shall be used only if the file1 or file2 operand refers to
+standard input.
 
-The option '-R, --dereference-recursive', which recursively follows
-symbolic links, has been added to zcat, zgrep, ztest and zupdate.
+zdiff now passes the options '-W' and '-y' to diff. (But it only works if
+the diff program used supports them).
 
-The option '-r, --recursive' now skips symlinks that are encountered
-recursively.
+Bzip2 and lzip files are now detected better.
+('echo LZIP | zcat' and 'echo BZh5 | zcat' no longer return an error).
 
-If no files are given to zcat, zgrep, ztest and zupdate, a recursive
-search will now examine the current working directory.
+ztest now continues checking the rest of the files if any input file is a
+terminal.
 
-Recursive directory loops are now detected.
+'ztest -v' now prints the number of files that failed the test (like lzip).
 
-zcat and zgrep now ignore directories given in the command line if
-'--recursive' is not specified, instead of reporting an error.
+zcat, zgrep, and ztest now check for errors when closing the input file in
+addition to checking when closing the input from the decompressor.
 
-Extra trailing slashes are now removed from directories given in the
-command line before recursing into them.
+Trailing data remaining in the data feeder to the decompressor are now
+correctly ignored.
 
-zcat and zgrep now show the right error when they can't open an input
-file instead of showing "No such file or directory".
+zupdate has been modified to support the new behavior of lzip 1.22's option
+'-o' while retaining:
+perfect backwards compatibility with older versions of lzip down to 1.20,
+good backwards compatibility with older versions of lzip down to 1.11,
+acceptable backwards compatibility with older versions of lzip down to 1.4.
 
-Killed decompressors are now waited for, preventing failure caused by
-too many open pipes.
+zupdate now keeps combined extensions: tgz, tbz, tbz2, txz --> tlz.
+This is useful when recompressing Slackware packages, for example.
 
-Test and document that if a file fails to decompress, zcat, zgrep and
-ztest continue processing the rest of the files.
+zupdate now puts single quotes around file names when calling zcmp to allow
+file names with spaces. (But putting spaces in file names is a bad idea).
 
-Test and document that if an error happens while recompressing a file,
-zupdate exits immediately without recompressing the rest of the files.
-
-The configure script now accepts appending options to CXXFLAGS using the
-syntax 'CXXFLAGS+=OPTIONS'.
+The descriptions of zcat, zcmp, and zdiff have been improved.
