What's New in This Release: [ read full changelog ]
· The biggest new feature is one requested by several users: password-based encryption for all files and filenames stored in images. SHA1+3DES are used in order to accomplish this; more details can be found by inspecting the source code.
· Revamped the user interface and added localization support for SEVEN new languages: German, Spanish, French, Japanese, Polish, Brazilian Portuguese, and Turkish.
· Numerous bug fixes were integrated, including (most glaringly) a bug that prevented users from extracting files from multiple images under certain non-trivial circumstances.
