KeePass 2.51

What's new in this version:

New Features:
- Most dialogs with fixed size now detect whether they fit onto the current screen, and when a dialog does not fit (e.g. due to a very high DPI factor), its size is reduced and scroll bars are displayed.
- Added plural entry command names in the main window (e.g. the command for editing the currently selected entry/entries is now called either 'Edit Entry' or 'Edit Entries', depending on the number of selected entries).
- Added tooltip for the main part of the status bar of the main window.
- Enhanced color buttons (tooltips, accessible names, ...) in the entry dialog, in the database settings dialog and in the options dialog.
- Added 'Interface (2)' tab page in the options dialog, renamed the existing 'Interface' tab page to 'Interface (1)', moved some controls from 'Interface (1)' to 'Interface (2)'.
- Enhanced font selection controls (with a checkbox that allows to return to the default, the button shows the currently selected font, tooltip, improved accessibility, ...) in the options dialog.
- Added help links 'Dark theme' and 'Main font (size)' in the options dialog.
- The options 'Custom alt. item color' and 'Esc keypress in main window' are now disabled if they are enforced (by an enforced configuration file).
- Added support for opening URLs with Waterfox in private mode.
- Added dialog for editing (HMAC-based and time-based) one-time password generator settings (can be opened using the 'OTP Generator Settings' commands in the entry dialog or in the 'Edit Entry (Quick)' menu of the main window).
- Added entry commands 'Copy HMAC-Based OTP', 'Show HMAC-Based OTP', 'Copy Time-Based OTP' and 'Show Time-Based OTP' (in the 'Other Data' menu).
- Added entry commands 'Copy Title' and 'Copy Notes' (in the 'Other Data' menu).
- When switching to the 'Generate' tab page of the password generator dialog (no database open), the entropy collection dialog is displayed now, if the option 'Show dialog for collecting user input as additional entropy' is turned on.
- Added option 'Colorize password characters' in the HTML export/print dialog; the colors are customizable.
- Added options 'Custom main font' and 'Custom password font' in the HTML export/print dialog.
- Added horizontal entry separator lines in tabular HTML exports/printouts.
- In the plugins dialog, the 'Delete old files from cache automatically' option and the 'Clear' button are now disabled if they are enforced (by an enforced configuration file).
- Plugins can now change the expiry date of an entry more easily.
- Added workaround for Wine bug 52457.
