New Features:
- Password quality estimation algorithm: added check for about 1500 most common passwords (these are rated down to 1/8th of their statistical rating; Bloom filter-based implementation).
- Global auto-type (using a system-wide hot key) is now possible on Unix-like systems (see the documentation for setup instructions, section 'Installation / Portability' in the 'KeePass 2.x' group; thanks to Jordan Sissel for enhancing 'xdotool').
- Added IPC functionality for Unix-like systems.
- Added possibility to write export plugins that don't require an output file.
- Tag lists are sorted alphabetically now.
- Password text boxes now use a monospace font by default.
- Added option to select a different font for password text boxes (menu 'Tools' -> 'Options' -> tab 'Interface').
- Added support for importing Password Prompter 1.2 DAT files.
- Added ability to export to Windows/IE favorites.
- Added ability to specify IO credentials in the 'Synchronize' trigger action.
- Added ability to specify IO credentials and a master key in the 'Open database file' trigger action.
- If IO credentials are stored, they are now obfuscated.
- Custom colors in the Windows color selection dialog are now remembered.
- Added high resolution version of the KeePass application icon.
- Improved lock overlay icon (higher resolution).
- PLGX loader: added support for unversioned KeePass assembly references.

Improvements / Changes:
- Added workaround to avoid alpha transparency corruption when adding images to an image list.
- Improved image list generation performance.
- Added workaround to display the lock overlay icon when having enabled the option to start minimized and locked.
- Improved group and entries deletion confirmation dialogs (with preview; only Windows Vista and higher).
- The password character picking dialog now offers the raw password characters instead of an auto-type encoded sequence.
- PINs importer: improved importing of expiry dates.
- Some button icons are now resized to 16x15 when the 16x16 icon is too large.
- Renamed character repetition option in the password generator for improved clarity.
- Improved workspace locking.
- Locking timer is now thread-safe.
- Added code to prevent loading libraries from the current working directory (to avoid binary planting attacks).
- Removed Tomboy references (on Unix-like systems).
- Various code optimizations.
- Minor other improvements.

Bugfixes:
- {NEWPASSWORD} placeholder: special characters in generated passwords are now transformed correctly based on context (auto-type, command line, etc.).
