    Reviewing 2.91 Beta (Nov 30, 2006)

    Well, about time that someone submitted the 2.9x beta series to FileForum :)

    The biggest change in the 2.9x series is the implementation of the LZMA algorithm. What this means is that your files have a MUCH better compression (even better than the --best option).

    For testing purposes, I compressed the AutoHotkey compiler executable (AutoHotkeySC.bin) with the --best and --lzma options:

    Original Size: 391 KB
    --best option: 205 KB
    --lzma option: 193 KB
