Hi all,
I'm writing to let you know that the upcoming release of Zettlr will be the last one to support Ubuntu 17.04 (released in 2017) and macOS 12 (Monterey; released 2021).
If you use either of these (or an older) version of the affected version, we recommend you update as soon as possible. Otherwise, the next-next release of Zettlr (again, not the upcoming one, the one after that) will not launch. This is a change coming in from Chromium dropping support; in the case of macOS due to the removal of some system APIs, and in the case of Ubuntu the full and complete deprecation of the Unity desktop environment.
This means: If you use Unity, but not Ubuntu, you will also be affected.
If you have any questions or concerns, just let me know.
