For anyone who has wanted to switch to KeePassX (to avoid mono dependencies, for instance), but needed the integration with keepasshttp, this project is active: https://github.com/Ivan0xFF/keepassx
I haven't switched yet to Ivan0xFF's port yet (I've been using the auto-type based on window title). I may not actually switch, as the Pass project some others have posted here looks very good as a cross-platform solution (e.g., there is an android app and Firefox plugin) and there are scripts for converting existing databases to the new keystore.
I love KeepassX, but the time it takes to add features and make releases is disencouraging. I don't like that I have to use a fork for months or years because the author is to proud to let in other main contributors (this concerns open source in general, but KeepassX is a great example for this).
