1. "Repair" command efficiency is improved for recovery record protected
RAR5 archives. Now it can detect deletions and insertions of unlimited
size also as shuffled data including data taken from several
recovery record protected archives and merged into a single file in
2. If encoding of comment file specified in -z<file> switch is not
defined with -sc switch, RAR attempts to detect UTF-8, UTF-16LE
and UTF-16BE encodings based on the byte order mask and data
3. "Update" and "Fresh" commands ('u' and 'f' in the command line mode)
quit immediately if no files are to be updated. Previously they
created a temporary archive before quitting when updating archives with
recovery record or quick open information.
4. "Repair" command issues "Recovery record is corrupt" message
after repairing RAR5 archive containing a broken recovery record.
Previously such message was issued only by "Test" command
and "Repair" handled most of recovery record damages silently.
5. Bugs fixed:
a) fixed potential security issues when processing corrupt
b) -tl and -tk switches did not work with archive modification
c) command like 'rar a arcname.rar subdir/arcname.rar' erroneously
issued "No files" warning and refused to add the file.
