LibGpiodV2 is no longer experimental (#2482)

pgrawehr · web-flow · commit 9c867ff2cf01 · 2026-03-14T18:03:25.000+01:00
* Remove some strange Unicode characters from file

* Remove some obsolete error messages

* LibGpiodV2Driver and all it's subclasses are no longer experimental

* Remove some more experimental flags, update documentation
