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.).
