KeePass 2.15

What's new in this version:

New Features:
- Added option to show the master key dialog on a secure desktop (similar to Windows' UAC; almost no keylogger works on a secure desktop; the option is disabled by default for compatibility reasons).
- Added option to limit the number of history items per entry (the default is 10).
- Added option to limit the history size per entry (the default is 6 MB).
- Added {PICKCHARS} placeholder, which shows a dialog to pick certain characters from an entry string; various options like specifying the number of characters to pick and conversion to down arrow keypresses are supported; see the one page long documentation on the auto-type help page; the less powerful {PICKPASSWORDCHARS} is now obsolete (but still supported for backward compatibility).
- The character picking dialog now remembers and restores its last position and size.
- KDBX file format: attachments are now stored in a pool within the file and entries reference these items; this reduces the file size a lot when there are history items of entries having attachments.
- KDBX file format: attachments are now compressed (if the compression option is enabled) before being Base64-encoded, compressed and encrypted; this results in a smaller file, because the compression algorithm works better on the raw data than on its encoded form.
- PLGX plugins can now be loaded on Unix-like systems, too.
- Added option to specify a database color; by specifying a color, the main window icon and the tray icon are recolored and the database tab (shown when multiple databases are opened in one window) gets a colored rectangle icon.
- New rich text builder, which supports using multiple languages in one text (e.g. different Chinese variants).
- Added 'Sort By' popup menu in the 'View' menu.
- Added context menu commands to sort subgroups of a group.
- Added option to clear master key command line parameters after using them once (enabled by default).
- Added application policies to ask for the current master key before changing the master key and/or exporting.
- Added option to also unhide source characters when unhiding the selected characters in the character picking dialog.
- Added ability to export custom icons.
- Added 'String' trigger condition.
- Added support for importing DataViz Passwords Plus 1.007 CSV files.
- Enhanced 1Password Pro importer to also support 1PW CSV files.
- Enhanced FlexWallet importer to also support version 2006 XML files (in addition to version 1.7 XML files).
- Enabled auto-suggest for editable drop-down combo boxes (and auto-append where it makes sense).
- Pressing Ctrl+Enter in the rich text boxes of the entry dialog and the custom string dialog now closes with OK (if possible).
- Added option to cancel auto-type when the target window changes.
- Auto-type on Unix-like systems: added support for key modifiers.
- Added '--saveplgxcr' command line option to save compiler results in case the compilation of a PLGX plugin fails.
- Added workaround for % .NET SendKeys issue.
- Added workaround for Mono bug 620618 in the main entry list.
