After a long break, I've finally released version 2.0. The number is meant to reflect the amount of work that went into this release. The biggest new feature is one requested by several users: password-based encryption for all files and filenames stored in images. I'm making use of SHA1+3DES to accomplish this; more details can be found by inspecting the source code or emailing me.
Additionally, I have revamped the user interface and added localization support for SEVEN new languages: German, Spanish, French, Japanese, Polish, Brazilian Portuguese, and Turkish. Many thanks to the folks at Babelzilla for providing the translations.
Finally, numerous bug fixes were integrated, including (most glaringly) a bug that prevented users from extracting files from multiple images under certain non-trivial circumstances.
As always, please let me know if any issues arise during the use of FireSteg.
