    The first non-beta version of PIM v2 has been released! In addition, this is some sort of final - since currently I have no spare time for further development.

    Okay, what's new:
    + Improved "Ratio Estimator" for more accurate ratio prediction, changed threshold
    + Fixed a bug with PAK files

    Great job!
    A question... what is exactly Ratio Estimator?

    2 suggestions easy to implement:
    - add a "cancel button", very useful.
    - add a progress bar o time elapsed counter... to know that the program is compressing (very apreciated in large files )

    This thing can "estimate" compression ratio - to see how well current file can be compressed without actual compression. This can be used for a different ways:
    + To detect incompressible files (currently this feature not used). This can save some time since PPMD is slowest on already compressed/random data.
    + To detect "bad" multimedia files. If current multimedia file is too compressible, we disable a special compression and use a baseline PPMD. This may improve compression on some weird MM files.

    Ill keep this suggestions for future releases! Currently, like I said, Ill make some break in PIM development. These days I have a small amount of spare time, and I want to spend it on further LZPM development. I already optimized arithmetic encoder, made other things... Audio codec - just currently had no luck with such thing, looks like hybrid-LZ is more likely my song...
