Apache PLC4X announcing end of community support due to missing funding
From https://plc4x.apache.org/
To be fair, it seems there is just about ~5 developers who have contributed more than 100 commits(https://github.com/apache/plc4x/graphs/contributors), with only three of them working on it for longer than one year. So it seems Christofer is just about the "core development team".
Looking around at the website and the GitHub repository, I can't find a single place to get community support either, it seems to only be commercial support now, so it seems Apache PLC4X is indeed no longer offering community support.
