-Changes in version 1.8:
+Changes in version 1.9:
-In test mode, pdlzip now continues checking the rest of the files if any
-input file is a terminal.
+The option '--loose-trailing', has been added.
-Trailing data shorter than a lzip header are now also reported.
+The test used by pdlzip to discriminate trailing data from a corrupt
+header in multimember or concatenated 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.
+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.
+
+A final diagnostic is now shown at verbosity level 1 (-v) or higher if
+any file fails the test when testing multiple files.
+
+A second '.lz' extension is no longer added to the argument of '-o' if
+it already ends in '.lz' or '.tlz'.
+
+In case of (de)compressed size mismatch, the stored size is now also
+shown in hexadecimal to ease visual comparison.
+
+The dictionary size is now shown at verbosity level 4 (-vvvv) when
+decompressing or testing.
