Codex usage limits reset after a cache-hit regression drained limits faster

ChatGPT usage limits were reset 58 days ago.

Some of you noticed limits drained faster in Codex, we root caused it to an optimization that we rolled back that had an impact on cache hit rates when compacting across long running sessions. We fixed this and have now reset usage limits for all accounts. Enjoy the weekend.
