We have moved the forum to https://forum.ngsolve.org. This is an archived version of the topics until 05/05/23. All the topics were moved to the new forum and conversations can be continued there. This forum is just kept as legacy to not invalidate old links. If you want to continue a conversation just look for the topic in the new forum.
Perhaps you are still using the sourceforge repository?
We moved to github now. Try syncing from the repository of
github.com/NGSolve
and you should have the most recent version available.
