+Changes in version 1.9:
 
-The new options '--in-slots' and '--out-slots', setting the number of input
-and output packets buffered during streamed decompression, have been added.
-Increasing the number of packets may increase decompression speed, but
-requires more memory.
+Plzip now reports an error if a file name is empty (plzip -t "").
 
-The default number of input packets buffered per worker thread when
-decompressing from non-seekable input has been increased from 2 to 4.
+Option '-o, --output' now behaves like '-c, --stdout', but sending the
+output unconditionally to a file instead of to standard output. See the new
+description of '-o' in the manual. This change is backwards compatible only
+when (de)compressing from standard input alone. Therefore commands like:
+  plzip -o foo.lz - bar < foo
+must now be split into:
+  plzip -o foo.lz - < foo
+  plzip bar
+or rewritten as:
+  plzip - bar < foo > foo.lz
 
-The default number of output packets buffered per worker thread when
-decompressing to non-seekable output has been increased from 32 to 64.
+When using '-c' or '-o', plzip now checks whether the output is a terminal
+only once.
 
-Detection of forbidden combinations of characters in trailing data has been
-improved.
+Plzip now does not even open the output file if the input file is a terminal.
 
-Errors are now also checked when closing the input file.
+The new option '--check-lib', which compares the version of lzlib used to
+compile plzip with the version actually being used at run time, has been added.
 
-The descriptions of '-0..-9', '-m' and '-s' in the manual have been
-improved.
+The words 'decompressed' and 'compressed' have been replaced with the
+shorter 'out' and 'in' in the verbose output when decompressing or testing.
 
-The configure script now accepts the option '--with-mingw' to enable the
-compilation of plzip under MS Windows (with the MinGW compiler). Use with
-care. The Windows I/O functions used are not guaranteed to be thread safe.
-(Code based on a patch by Hannes Domani).
+When checking the integrity of multiple files, plzip is now able to continue
+checking the rest of the files (instead of exiting) if some of them fail the
+test, allowing 'plzip --test' to show a final diagnostic with the number of
+files that failed (just as 'lzip --test').
 
-The configure script now accepts appending options to CXXFLAGS using the
-syntax 'CXXFLAGS+=OPTIONS'.
+Testing is now slightly (1.6%) faster when using lzlib 1.12.
 
-It has been documented in INSTALL the use of
-CXXFLAGS+='-D __USE_MINGW_ANSI_STDIO' when compiling on MinGW.
+When compressing, or when decompressing or testing from a non-seekable file
+or from standard input, plzip now starts only the number of worker threads
+required.
+
+When decompressing or testing from a non-seekable file or from standard
+input, trailing data are now not counted in the compressed size shown.
+
+When decompressing or testing a multimember file, plzip now shows the
+largest dictionary size of all members in the file instead of showing the
+dictionary size of the first member.
+
+Option '--list' now reports corruption or truncation of the last header in a
+multimenber file specifically instead of showing the generic message "Last
+member in input file is truncated or corrupt."
+
+The error messages for 'Data error' and 'Unexpected EOF' have been shortened.
+
+The commands needed to extract files from a tar.lz archive have been
+documented in the manual, in the output of '--help', and in the man page.
+
+Tarlz is mentioned in the manual as an alternative to tar + plzip.
+
+Several fixes and improvements have been made to the manual.
+
+8 new test files have been added to the testsuite.
