Export to CSV in Monitoring → Problems now exports problems from all pages, not just the selected page. Filter settings are still obeyed.
The "guest" user is now disabled by default in new installations.
In previous versions, when logged in as guest, there was no way to tell what user you were logged in as, because the profile icon was hidden for the guest user. In the new version a slightly different version of the profile icon is displayed when you are logged in as guest - . This icon is not clickable and does not lead to the user profile. When the mouse is positioned over it, info is displayed with the name 'guest' to suggest the currently logged in user.
