New Features:

• Completely new plugin architecture (exposing a lot more functionality to plugins, faster, requires less memory, safer memory management / cross-module calls, more secure, and allows independent development of KeePass and plugins, i.e. starting with 1.15 KeePass can be updated without requiring plugins to be updated and vice versa).
• Added option to use advanced in-memory protection (DPAPI, only Windows Vista and higher; the key is stored in a secure, non-swappable memory area managed by Windows; option enabled by default).
• The hash of the master key and its transformed version are now in-memory protected.
• Added help source selection dialog (by default the online help center is used).
• Added '-set-urloverride', '-clear-urloverride' and '-get-urloverride' command line options.
• Focused disabled menu items are now drawn with a transparent selection rectangle.
• Windows XP and higher: added support for double-buffering in the entry list.
• Windows Vista and higher: added support for alpha-blended marquee selection in the entry list.
• Added KeeForceAllowChangeMasterKey, KeeForceAllowPrinting, KeeForceAllowImport and KeeForceAllowExport configuration options (these override the option to disable unsafe operations and the mini mode setting; they are only loaded from the enforced and global INI files, not the local one).
• Added KeeDisallowPrintingPasswords configuration option to disallow printing passwords and viewing them in the print preview.
• Added multi-user documentation.

Improvements:

• Improved plugin loading performance.
• Plugins don't need to be manually enabled anymore (just copy the plugin files into the KeePass application directory).
• Improved main menu items order.
• Improved main menu accelerators.
• Improved group main menu item texts.
• Improved performance of various entry list operations.
• Hash of master key is now cleared when closing a database.
• Hash of file key is now cleared after opening/saving files.
• Various code optimizations.
• Minor other improvements.

Bugfixes:

• Fixed cursor navigation problem in secure edit controls.
• Fixed random access violation in OnScreenKeyboard plugin.
