-Changes in version 1.6:
+Changes in version 1.7:
 
-The option '-l, --list' has been ported from lziprecover.
+When compressing on a 32 bit system, plzip now tries to limit the memory
+use to under 2.22 GiB (4 worker threads at level -9) by reducing the
+number of threads below the system's default.
 
-It is now an error to specify two or more different operations in the
-command line (--decompress, --list or --test).
+The option '--loose-trailing', has been added.
 
-In test mode, plzip now continues checking the rest of the files if any
-input file is a terminal.
+The test used by plzip to discriminate trailing data from a corrupt
+header in multimember regular (seekable) files has been improved to a
+Hamming distance (HD) of 3, and the 3 bit flips must happen in different
+magic bytes for the test to fail. As a consequence some kinds of files
+no longer can be appended to a lzip file as trailing data unless the
+'--loose-trailing' option is used when decompressing.
+Lzlib 1.10 or newer is required for this test to work on non-seekable
+files.
+Lziprecover can be used to remove conflicting trailing data from a file.
+
+The 'bits/byte' ratio has been replaced with the inverse compression
+ratio in the output.
+
+The progress of decompression is now shown at verbosity level 2 (-vv) or
+higher.
+
+Progress of (de)compression is only shown if stderr is a terminal.
+
+A second '.lz' extension is no longer added to the argument of '-o' if
+it already ends in '.lz' or '.tlz'.
+
+The dictionary size is now shown at verbosity level 4 (-vvvv) when
+decompressing or testing.
+
+The new chapter "Meaning of plzip's output", and a block diagram of
+plzip have been added to the manual.
