FreeArc 0.40 is major revision of the program. Main changes from previous version are:
· Full Russian docs (English translation will be made later)
· Multimedia compression using TrueAudio, GRZIP and MM filter (controlled by -mm option)
· Addition of delta filter improved compression of binary files by 2%
· Using temporary files for memory-hungry compression modes allowed to double maximum dictionary size that sometimes increases compression by up to 10%
· Enabling LZMA multithreading made compression 1.5x faster on dual-core CPUs (-mt)
· Fast Tornado compression used in –m1 and –m2 modes, providing zip-like compression levels with 3 times better speed (10-50 mb/sec)
· Support for user-defined external compressors in arc.ini, so now you can use your favorite compressors (LPAQ, PPMonstr, CCM and any other) inside .arc archives
· Encryption of data and archive headers using AES, Blowfish, Twofish and Serpent algorithms; support for cipher chaining (e.g., aes+twofish+serpent) and keyfiles (-p, -hp, -kf, -ae, -op, -okf)
· FAR and Total Commander plugins were updated to support all the new FreeArc features and fix old problems J
· Win32 and Linux-i386 versions plus sources with easy-to-follow building guide
There is also number of minor changes:
· Use -mx for maximum internal compression
· Use -max for maximum compression involving external programs (PPMonstr, ECM and Precomp as defined in shipped arc.ini)
· It’s possible to use filelists and comment files stored in OEM, ANSI, UTF-8 and UTF-16 encodings (-sc)
· -env and –cfg options may be used to select alternative settings / config file
· RAR-compatible options for filtering files by modification time, size and name (-ta, -tb, -tn, -to, -sl, -sm, -n)
· Archives can be listed/extracted directly from the Internet: arc x http://www.haskell.org/bz/arc.arc
· Archives can be restored using original from Internet: arc r bad.arc --original=http://www.haskell.org/bz/good.arc
· New ‘lb’ command lists bare names of files in archive
· ‘y’ command renamed to ‘ch’ for compatibility with RAR; -pt option renamed to -tp
· No more need to add “--recompress” when recompressing archives using “ch” command: try “Arc ch archive –mx”
· --display option was greatly enhanced; use -di to quickly enable displaying all information
· -z also works on archive extraction, saving archive comment to a file
· Improved help displayed by “Arc”, added help to user queries
· Temporary files are deleted when exiting by Ctrl-Break; all errors and warnings are reported to stderr, logfile and program exit code
· Renamed groups in arc.groups config file: $audio -> $wav, $rgb -> $bmp; added $precomp, $jpg, $iso groups
