MZLA Technologies Corporation has released Thunderbird 68.5.0; this is the first release of Thunderbird under the newly founded parent company that is a wholly owned subsidiary of Mozilla Foundation.
Thunderbird 68.5.0 is already available via the email client’s built-in updating system but also as a direct download on the project’s official website Thunderbird.net.
Thunderbird users may select Help > About Thunderbird to run a check for updates from within the client. The new version should be picked up, downloaded and installed automatically at that point. A restart is required to complete the process.
Thunderbird 60.x installations are not automatically upgraded to the new version unless the calendar add-on Lightning is installed.
The long-standing issue when upgrading from Thunderbird 60.x to 68.x has not been fixed yet. Installed extensions are not updated automatically during the upgrade process; this may be necessary for compatibility purposes and some add-ons may be disabled as a consequence. The integrated update check for add-ons will check for new versions of installed extensions after the upgrade however.
The new version of the email client comes with two new features:
Both extend compatibility and are welcome additions to the email program’s list of supported features.
The official release notes list four non-security fixes (three of which fix Calendar issues):
Additionally, Thunderbird 68.5.0 includes several security updates. The list of fixed security issues reveals high, moderate and low issues that the team fixed in the new release.
