[RESOLVED]
Same issues that were happening two weeks ago are happening again right now. I have alerted relevant parties to the problem.
For now, new plugin authors won’t be able to commit, and some plugin readme.txt files won’t get processed correctly until this is corrected.
Sorry for the inconvenience.
Edit: This seems to be fixed for the moment, we’re working on preventing future recurrences.
ETA2: If your plugin is still missing, we know and we’re working on it.
