RAR - What's new in the latest version
Version 2.60 beta 8
1. Switch -- (stop switches scanning) did not work in
the previous beta.
Version 2.60 beta 7
1. Commands "vt" and "lt" are updated to display information
about BeOS host OS and BeOS extended attributes.
Note that RAR/BeOS version now is available for download
on www.rarsoft.com
Version 2.60 beta 6
1. Compression speed is significantly increased, by 30 - 40%
and sometimes even more depending on data types. Memory
requirements also are increased a little and now are about
7.5 MB, when using 1024KB dictionary.
Version 2.60 beta 5
1. Increased compression of files contained regular data structures
like executables and databases. My thanks to Alexander Khoroshev
for help in achieving it.
2. Bugs fixed:
- RAR does not write more "All OK" after extraction,
if broken file headers are found;
- switches -cl and -cu did not work when creating an archive.
Version 2.60 beta 3
1. Switch -ag now can have an optional parameter - format string.
Version 2.60 beta 2
1. RAR beta 1 was not able to handle "switches=" command in .rarrc
and rar environment variable. Fixed in beta 2.
2. For better compatibility with different Linux versions RAR now
is linked using static libraries.
Version 2.60
1. Information for registered users:
WinRAR and Rar for Linux versions 2.60 and above are registered
with a new, very secure, AV registration seal. The main advantage
of this new authenticity verification code is a significant
increase in the strength of the registration code and thus it's
use as a means of identification of the origin of a sealed archive.
Unfortunately this also means that the old registration keyfiles
will not operate with the latest versions of Rar-Linux and WinRAR
and thus all keyfiles must be changed. This is a cost-free process
to the registered user.
Please read rereg.txt file for detailed instructions on updating
your keys.
2. Packing speed in the "Best compression" mode has been improved.
My thanks to Bulat Ziganshin for the hint which allowed me to
achieve this.
3. Increased speed of scanning for large numbers of files before
archiving operations. Memory management also is optimized,
so now it is possible to handle hundreds of thousands,
or even millions of files.
4. RAR shows the total percentage of processed data when archiving
instead of the current file percentage as before.
5. New switch -df - "Delete files after archiving". Command
"rar a -df" is equal to "rar m".
6. New switch -ag - "Generate archive name using the current date".
Appends string "DDMMYYHHMMSS" to an archive name when creating an
archive. Useful for daily backups.
7. New switch -as - "Synchronize archive contents". If this switch
is used when archiving, those archived files which are not
present in the list of the currently added files, will be deleted
from the archive. It is convenient to use this switch in
combination with -u (update) to synchronize the contents of an
archive and an archiving directory. For example, after the
command:
rar a -u -as backup sources\*.cpp
the archive 'backup' will contain only *.cpp files from sources
folder. It looks similar to creating a new archive, but with the
one important exception - if no files are modified since a last
backup, this operation is performed much faster than creation of
new archive.
8. Unrar sources are removed from the distributive. You can download
them separately from www.rarsoft.com. This is to reduce size of
the RAR package.
9. Command "S" now can be applied to an existing SFX archives
to replace one SFX module with another.
Version 2.50
1. Now RAR/Linux accepts same registration codes as RAR/DOS
and WinRAR, so a single registration is enough for the all
three platforms. Already registered RAR/Linux users should
write to ron@knowledgebase.fi to obtain new keys for free.
2. Both packing speed and compression ratio have been improved.
3. CRC of packed data is now stored for file parts split between
volumes. It allows localization of a damaged volume, if volumes
set contains one large compressed file.
4. New command line switches:
a) -sv - create independent solid volumes. This switch has
the same meaning as the option "Independent solid volumes"
described above;
b) -ap<path> - set path inside archive. It allows to add files
to a specified archive folder when archiving or to remove
the specified part of path from file names when extracting;
c) -- switch stops further switches scanning. It can be useful,
if you need to use in the command line a file or archive name
beginning with '-' character.
5. RAR home page is moved to www.rarsoft.com
