Thunderbird 156.0.1 Fixes a Crash When Saving Messages

Mozilla has released Thunderbird 156.0.1, a quick follow-up to last week's 156.0 release. The update fixes a single but annoying bug, and it is already rolling out through Thunderbird's built-in updater. Users on the Extended Support Release also get a new build, 153.3.1 ESR, which Mozilla says contains no changes that require release notes.

What's New in 156.0.1

• Crash fix: Thunderbird could crash when saving a message. That no longer happens.

A Quick Recap of Thunderbird 156.0

If you are coming from an older version, 156.0.1 also includes everything that arrived with 156.0:

• Yandex sign-in: Yandex accounts now sign in through your external web browser.
• OpenPGP diagnostics: Key properties can write debug information to the Error Console.
• New enterprise policies: Admins can lock update settings and data collection settings, and can block message filters from forwarding mail automatically.
• Thundermail add-on: The built-in add-on is updated to version 2.0.11.
• Bug fixes, including:
  • PDF attachments opened in a tab no longer show up blank.
  • Pressing Enter on the Windows tray icon now restores the Thunderbird window.
  • SMTP sign-in now works with usernames that contain non-ASCII characters.
  • Renaming a folder no longer resets its settings.
