Changes from 1.09 to 1.10:
New Features:
Added configuration file caching (highly increases performance when running KeePass from slow devices like USB sticks).
Added key provider API (it now is very easy to write a plugin that provides additional key methods, like locking to USB device ID, certificates, smart cards, ... see the developers section in the online KeePass help center).
Added support for environment variables in URLs and paths (%-syntax support for field placeholders was removed because it conflicts with the environment syntax, see the 'Upgrading to KeePass 1.10' article).
Added {INTERNETEXPLORER}, {FIREFOX} and {OPERA} application path placeholders (can be used in URLs and auto-type).
Added support for starting very long command lines.
Added mini mode (must be configured in the INI file manually; in mini mode, a lot of functionality is hidden; see help file - Technical FAQ).
The quick find control in the main window now remembers the most recent searches (if you want the search texts to be remembered across sessions, you need to save the database).
Added password generator option to exclude/omit user-specified characters in generated passwords.
Added option to disallow repeating characters in generated passwords (both character set-based and pattern-based).
Moved security-reducing / dangerous password generator options to a separate 'Advanced' dialog (if you enable a security-reducing option, the 'Advanced' button in the password generator window is shown in red).
Added ability to search using a regular expression.
Internal random number generator is now additionally seeded using random bytes provided by the system's default CSP.
Internal random number generator is now additionally seeded using a newly generated 128-bit GUID.
A default user name for new entries can now be specified in 'File' -> 'Database Settings'.
Added ability to specify the groups that are automatically created when creating a new database (in the INI file).
Banner colors can be changed in the INI file now (KeeBannerColorStart and KeeBannerColorEnd, set to BGR-Quads).
XMLImport plugin: entries with no or empty UUIDs are supported now (KeePass generates new random UUIDs for them).
KeePass now registers a global sync. application mutex: 'KeePassAppMutexExI' (+ updated Windows installer).
Added an advanced option to disable the Ctrl-Alt-K hot key.
Added textual cue for the quick-search edit control.
The TAN wizard now shows the name of the group into which the TANs will be imported.
Improvements:
Changed field order: password follows user name now (note: if you use your previous configuration file, the columns in the main window will be ordered the old way; to change it, drag&drop the column headers manually to adjust the order).
Code improvements (developers: KeePass now requires the Boost C++ libraries to compile).
Empty fields are not shown in the entry details view any more.
Improved startup time.
Improved search performance.
Improved internal menu handling.
Group export menu items are now named more consistently.
Improved print options dialog (replaced "export" by "print", excluded irrelevant export options, ...).
Search results list display mode is now adjusted based on matching items.
When trying to open a database that already is currently opened by someone else, you are not prompted any more whether to open it in read-only mode, if the '-readonly' command line argument is present in the current instance.
Entry list is now automatically focused after a Ctrl-F search and the first item is selected.
Improved default global configuration file (shipped in setup).
Improved title drawing in dialog banners.
Improved entry list update behavior when there are no groups.
KeePass now uses the default shell verb for opening URLs and files instead of 'open'.
Optimized performance of process memory protection algorithm.
The status bar is now updated immediately after performing a quick search (main window).
Search results are not cleared any more when having an auto- sorting option enabled and performing an operation that modifies a search results entry (like auto-type).
Replaced 'Gen' button by an image button.
Minor improvements in the installer.
Minor improvements in cmd:// URL handling.
Minor dialog text improvements.
Bugfixes:
Password generator does not crash any more when trying to generate a password using an empty pattern + random permuting.
The Ctrl-Alt-K global hot key correctly brings the KeePass main window to front when it's hidden behind other windows.
Changing the state of the 'Randomly permute characters of password' option now correctly selects the '(Custom)' profile.
