Thunderbird 115 is the last version for Windows 7 and 8
The team that is responsible for the open source email client Thunderbird has released Thunderbid 115 earlier this week. The new version of the email client features a new design and several new features, including new folder views, different new layouts for the client, improved calendar and address books and more.
The new release is not yet available via the built-in updating functionality of the email client, and it may take a while before the upgrade is enabled. Some users noted that some of their extensions stopped working in the new Thunderbird and there are issues to be sorted out first.
Support for older versions of Windows and macOS
Thunderbird 115 will be the last version that is compatible with Microsoft's Windows 7, 8 and 8.1 operating systems. It furthermore is also the last version compatible with Apple's macOS 10.12, 10.13 and 10.14 systems.
Microsoft ended support for Windows 7 and 8.1 in January 2023. These operating systems are no longer supported by Microsoft. Similarly, Apple does not support the older macOS versions anymore.
Most Windows 7 and 8.1 devices can be upgraded to Windows 10, a version of Windows that is supported until October 2025. Microsoft did not change the system requirements between the older versions of Windows and Windows 10.
Thunderbird 115 supports the operating systems. The email client will be supported until late 2024, just like Mozilla Firefox 115 ESR.
Thunderbird users on these operating systems will receive the update to Thunderbird 115 eventually, just like users on newer systems. The email client will then receive regular updates throughout 2023 and most of 2024 on the older systems.
Users on these systems can't install newer versions of Thunderbird anymore, however. Thunderbird 116, which is available as a Beta currently, won't install on these systems anymore.
Windows 7 and 8 users, and macOS 10.14 and earlier users, may continue using Thunderbird until late 2024. This should give most users ample time to move on to a new operating system on the same device or another device.Advertisement
