OP, you can go to
https://wiki.project1999.com/Patch_Notes and compare this to the current Green timeline to figure out an estimate of when changes/patches are supposed to go in. This will not be a strict schedule (volunteer dev team etc), but at least a rough idea.
I don't feel like doing this right now. People keep asking this question and those people should do it.
