Release Notes

7-Zip 9.20.05 alpha was released.

 

What’s new:

– 7-Zip now can unpack UEFI BIOS files.

– 64-bit version of 7-Zip now includes additional 32-bit shell extension DLL.

So other 32-bit programs can call 64-bit 7-Zip via context menu.

– Now it’s possible to associate 7-Zip with file types without Administrator rights.

– New -mf=FilterID switch to specify compression filter. Examples:

7z a -mf=bcj2 a.7z a.tar

7z a -mf=delta:4 a.7z a.wav

7z a -mf=bcj a.tar.xz a.tar

– There are some changes in LZMA settings for BCJ2 filter.

So compression ratio now is slightly improved for executable files in -mx9 mode for .7z format.

– Some bugs were fixed.

– New localizations: Corsican, Kyrgyz.

 

Notes:

The code that parses -m switch has been rewritten. So if you see any bug with -m switch, please write here: http://sourceforge.net/projects/sevenzip…ic/4363048
