Where is anki development headed?

I wrote the addon Stepwise Map Retrieval about a year ago and started reworking the whole project a couple of weeks ago. Now I noticed that the anki codebase has changed a lot since the last time I looked into it. To make the addon as stable as possible with respect to future releases it would be very nice to know how anki is supposed to develop in the future. Then I would have a better understanding of where it makes sense to set the entering points of my addon and which parts of the code better not to touch. Is there any resource like a backlog or something where I can see what is planned for anki development?
