Hi Rafał! We are in the process of simplifying the contribution process. To do this, we plan to remove the "Community Resolved" state. This will directly affect your "Community Resolved" issues.
Where will your ticket go? It will be moved to "Contributed Solution". So this message is a notice that we will perform this move soon.
Once we do make the move, there will be one less step in getting your contribution implemented. Thanks for your hard work!
