What's new in this version:

Support for many new formats and algorithms:
- Partial support for SITX archives. Most archives should open fine, but SITX's special JPEG compression is unsupported. (If you are a programmer and want to help out with getting this working, I'd be happy to hear from you!) Some preprocessing filters are also nsupported.
- Other new formats: XAR, ALZip, LZMA-utils, Compact Pro, PackIt, ARJ
- Encrypted RAR archives.
- WinZip-style encrypted Zip files using AES.
- Can decompile NSIS installers to get the files inside. This seems to work for versions all the way back to 1.1o or so, but a lot of guessing is involved so it might fail on some files.
- More compression types in Zip: Deflate64, bzip2, PPMd, LZMA.
- More compression types in DiskDoubler (but still not all).
- Better handling of 7-zip, RAR, LZH, tar and RPM files.
- Extracting files from several emulation formats, such as NDS and ADF.

- Bug fixes and streamlining for the user interface.
- Option for when to create folders for extracted files.
- Option for how to set the date of extracted folders.
