Thunderbird 151 and the new OAuth authentication with automatic account configuration
One of the most relevant changes in the Thunderbird 151 is the Adding OAuth login for Thundermail along with automatic account setup. This allows users to enter their credentials without needing to manually configure IMAP, SMTP, or Exchange servers in many cases.
