1.39 - Location of the folder caches may now be changed in settings
1.38 - Faster displaying of messages that have already been downloaded to disk - When marking all messages in a folder as read, perform the action in steps instead of trying to mark all messages at once to workaround Outlook servers timing out
1.37 - Caching email contents locally is now several times faster - Enabling caching for folder or account immediately starts downloading all emails - Disabling local cache for folder or account wipes all downloaded emails - Fixed a bug where email address autocomplete wouldn't pick up any results from Contacts - Fixed a bug in SelectAll/None/Unread functionality when used from the mail list context menu
