I've noticed that since February there have been an increasing number of pull requests on the Marlin firmware github which remain unmerged. Requests for information on what changes or actions should be done to get them merged have gone unanswered. [Erik thankfully last week committed a few of the smaller changes.]
Now of course there could be quite a number of reasons for this - people away, other priorities, disagreement with the pull request itself, a move away from Marlin/Arduino to ARM, or a change in the level of support for Marlin firmware maintenance by Ultimaker.
I was just wondering if anyone can let us know what the story is (I'm not try to blame anyone here just understand the situation). I'm sure there are many in the community who would be willing to help out if the current maintainers are overloaded.
