v4.4.2: Prepare for KeePass 2.61

If the option 'Check for update at KeePass startup' is activated, KeePass 2.61 will initiate the update check before trying to open a database (asynchronously). If an update is found while a master key prompt dialog is displayed, the availability of the update is now indicated by a banner in the dialog.
As preparation for that, this part has been removed from EarlyUpdateCheck if KeePass >= 2.61 is used.

One-Click plugin update and the enhancements to the plugins form are still available

v4.4.1 - Improve one-click plugin update

Better detection of other plugins
Use default update URL for plugins if not specified differently

v4.4: Internal improvements & KeeTheme support

v4.3 brought internal improvements but was not released individually as v4.4 was finished shortly afterwards
v4.4 brings KeeTheme support

v4.2.4: Improve updates of other plugins

Allow downloading plugins with build version being 0 - e.g. someplugin-1.2.0.plgs
Add Readable Passphrase Plugin to external plugins that can be updated

v4.2.3: Bugfix: Update plugins with empty build field

Better support for plugins that don't contain a build field in the version tag, e. g. 2.1 instead of 2.1.0

v4.2.2: Add compatibility to KeePass 2.55

Ensure plugin versions are shown in plugin overview

v4.2.1: Bugfix: UAC prompt cannot be shown if secure desktop was used

If key prompt form or key creation form were shown on the secure desktop, the UAC prompt cannot be shown any more.
In that case, now the created temp folder can be opened and you can copy the files yourself

v4.2: Improvements & enhancements when updating plugins

Technical improvements to allow updating more plugins

Added some more plugins that can be updated:
 - KeePassWinHello
 - KPEntryTemplates
 - KPSimpleBackup

v4.1.4

Bugfix: Update of ExternalPluginUpdates.xml now works properly

v4.1.3: Add compatibility with secure desktop mode

EarlyUpdateCheck now properly detects usage of secure desktop and delays displaying the update form.
Using secure desktop does not allow to show the update form right away.
