-Changes in version 1.19:
+Changes in version 1.20:
-'--merge' is now able to fix files with thousands of scattered errors
-per member by grouping the errors into clusters and then merging the
-files as if each cluster were a single error.
+Splitting was broken for files larger than 64 KiB because of a bug
+introduced in version 1.16.
-The option '-a, --trailing-error' now works with '-l, --list' and
-'-D, --range-decompress'.
+The options "--dump-tdata", "--remove-tdata", and "--strip-tdata" have
+been added to ease the management of metadata stored as trailing data:
-The output of option '-l, --list' has been simplified to make it easier
-to read.
+ "--dump-tdata" dumps the trailing data (if any) of one or more regular
+ files to standard output.
-In test mode, lziprecover now continues checking the rest of the files
-if any input file is a terminal.
+ "--remove-tdata" removes the trailing data from regular files in place.
-Trailing data are now shown both in hexadecimal and as a string of
-printable ASCII characters.
+ "--strip-tdata" copies one or more regular files to standard output,
+ stripping the trailing data (if any) from each file.
+
+The option '--loose-trailing', has been added.
+
+The test used by lziprecover 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 contents of a corrupt or truncated header found in a multimember
+file is now shown, after the error message, in the same format as
+trailing data.
+
+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 decompression is only shown if stderr is a terminal.
+
+A final diagnostic is now shown at verbosity level 1 (-v) or higher if
+any file fails the test when testing multiple files.
+
+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.
