What are your plans regarding this update? Yes, the plans are still there. I'm only wondering what would be the best time to switch - right now within the branch or a bit later once the branch is merged and the new code settles down a bit? I can see a slight advantage of the latter approach of having a greater chance of separating problems caused by the merge and problems caused by the SIP API change, but I do not have a strong opinion here. > I'm also looking forward to seeing QgsFeatureRequest support QgsExpression, > I think this is not yet supported? No, it's not yet supported. It should be possible to add features like this one easily even later without breaking any API. It is not my priority now, of course any contributions in that direction are welcome!
