Our Download of the Day is Thunderbird 11.0.1.
Thunderbird 11.0.1 is now out and includes two fixes, and still sports an unresolved issue. The two fixes include an issue that causes Thunderbird to hang when handling IMAP mail, and the second fix is an issue that may cause filters that move mail to specific folders to erronously changed. An unresolved issue is where if you're unable to view content for your RSS feeds in the Wide View Layout, you may need to disable the Lightning Calendar add-on if you have it installed, or switch to Classic View and restart Thunderbird.
