RAR - What's new in the latest version
Version 5.50 beta 1
1. RAR uses RAR 5.0 archive format by default. You can change it to
RAR 4.x compatible format with -ma4 command line switch.
2. Added support for 1 nanosecond file time precision on Unix platform.
3. You can specify 'f' charset value in -sc switch to use UTF-8
encoding. For example:
rar a -scfl arcname @filelist.txt
to read contents of filelist.txt as UTF-8 text.
4. RAR "lt" and "vt" commands display file times with nanosecond
precision. Such precision is used in RAR5 archives created
by RAR/Unix 5.50. Archives created by Windows RAR version
have 100ns file time precision.
5. Only '+', '-' and '1' precision modifiers are supported
in -ts switch now. Use '+' to store the file time with maximum
precision, '-' to omit the file time and '1' to store it with
1 second precision. Intermediate precision modes previously
defined with '2' and '3' modifiers are not available in RAR 5.0
archive format and ignored by -ts switch.
6. If a wrong password is entered when unpacking an encrypted file
in RAR5 archive, RAR proposes to enter a valid password
for same file again instead of aborting extraction.
7. Bugs fixed:
a) directory owners were not set when extracting RAR5 archives
created with -ow switch;
b) if only creation or only last access file time was stored in RAR5
archive with 1 second precision, such as with -ma5 -tsm- -tsa1
switches, this stored time was ignored when extracting.
