New Features:

• Header data in KDBX files is now authenticated (to prevent silent data corruption attacks; thanks to P. Gasti and K. B. Rasmussen).
• Added management of working directories (a separate working directory is remembered for each file dialog context; working directories are remembered relatively to KeePass.exe; the management can be deactivated by turning off the new option 'Remember working directories').
• Added option to cancel auto-type when the target window title changes.
• Added quick search box in the toolbar of the internal text editor.
• Files can now be attached to entries by using drag&drop from Windows Explorer to the attachments list in the entry editing dialog.
• Added '-pw-stdin' command line option to make KeePass read the master password from the StdIn stream.
• Added placeholders to get parts of the entry URL: {URL:SCM}, {URL:HOST}, {URL:PORT}, {URL:PATH} and {URL:QUERY}.
• Added a 'Details' button in the plugin load failure message box (when clicked, detailed error information for developers is shown).
• Added warning icon left of the Windows user account option description in the master key creation dialog.
• Added support for more image file formats (e.g. when importing custom client icons).
• Added support for importing DesktopKnox 3.2 XML files.
• The generic CSV importer now guesses whether the option to ignore the first row should be enabled or not (the user of course can still specify it manually, too).
• Added support for exporting to KeePass 1.x CSV files.
• Added support for moving the PLGX cache to a different remote drive.
• The Spr engine is now extensible, i.e. plugins can provide additional transformations/placeholders.
• On Unix-like systems, KeePass now uses the 'xsel' utility for clipboard operations, if 'xsel' is installed (in order to work around Mono clipboard bugs).
• Added Mono workaround to set the WM_CLASS property.
• Added workaround for Mono splitter bug.
• The 'PrepMonoDev.sh' script now removes the serialization assembly generating post build event.
• TrlUtil: added support for importing PO files.
