KeePass 2.31

What's new in this version:

New Features:
- Added menu/toolbar styles, freely selectable in 'Tools' -> 'Options' -> tab 'Interface'; available styles are 'Windows 10', 'Windows 8.1', 'KeePass - Gradient', '.NET/Office - Professional' and 'System - Classic'; by default KeePass uses the style most similar to the one of the current operating system.
- Refined application icons (thanks to Victor Andreyenkov).
- Auto-Type: new target window classification method, which improves compatibility with target windows hosted within other windows (e.g. a PuTTY window within SuperPuTTY/MTPuTTY).
- Auto-Type: added workaround for the default Ctrl+Alt behavior of KiTTY variants (which differs from Windows' behavior).
- Before clearing the clipboard, KeePass now first copies a non-sensitive text into it; this ensures that no sensitive information remains in the clipboard even when clearing is prevented by the environment (e.g. when running in a virtual machine, when using a clipboard extension utility, ...).
- Added support for opening entry URLs with Internet Explorer or Google Chrome in private mode via the context menu -> 'URL(s)' -> 'Open with ... (Private)'.
- Added URL override suggestions for Internet Explorer and Google Chrome in private mode in the URL override suggestions drop-down list in the entry dialog.
- Added optional built-in global URL overrides for opening HTTP/HTTPS URLs with Internet Explorer or Google Chrome in private mode.
- Added Ctrl+K shortcut for the 'Duplicate Entry' command.
- Mozilla Bookmarks HTML import: added support for importing tags.
- Added support for exporting to Mozilla Bookmarks HTML files.
- Windows/IE favorites export: entry fields are Spr-compiled now, and entries with cmd:// URLs are now exported as LNK files.
- HTML export/printing: added support for UUIDs, added horizontal lines between entries in details mode, added background color for group headings, long field names are hyphenated now, and long field data now breaks and wraps onto the next line.
- Plugins: added possibility to configure file transactions for each URI scheme.
- Plugins: added possibility to provide custom 'Save As' dialogs more easily.
- Converted some PNG images as a workaround for a problem in Cairo/LibPNG on Unix-like systems.
- As a workaround for a weakness in Mono's FileDialog, before showing such a dialog on Unix-like systems KeePass now tries to load the file '~/.recently-used' and deletes it, if it is not a valid XML file.
- KPScript: added support for specifying the master password in encrypted form using the '-pw-enc:' command line parameter (exactly like in KeePass, compatible with the {PASSWORD_ENC} placeholder).
- KPScript: the 'Export' command now supports the optional '-GroupPath:' parameter (to export a specific group instead of the whole database).
- KPScript: the 'GetEntryString' command now supports the '-FailIfNoEntry' option.
- KPScript: added '-refx-Expires' and '-refx-Expired' entry identification parameters.
- KPScript: the 'Import' command now prints more specific error messages.
- All KeePass program binaries are now dual signed using SHA-1 and SHA-256.
