New packing and unpacking functions for 7-Zip and tar.bz2 archives, as well as several bugs fixed

win.rar GmbH and RARLAB present for download the latest update of the compression and archive-management program: WinRAR 3.91.

This version can unpack 7-Zip archives, which have been created with the LZMA2 algorithm. Similarly the unpacking of 7-ZIP archives with encrypted file names from the context menu of the Windows Explorer has been optimized. The latest WinRAR also displays CRC32 of files inside usual .gz (not .tar.gz) archives. Previous versions left this field blank for GZIP files.

Completely new is the possibility to open tar.bz2 archives, which comprise of several smaller bz2 streams merged together. Previous WinRAR versions unpack only the first nested bz2 stream in such composite archives.

A complete list of fixed bugs could be found here:
