Over the next 28 days, each day we’ll either ship one thing that is a clear improvement and relevant for most codex/work users or ship a full reset. Let the improvements begin.

Days are filled from Tibo Sottiaux’s “Day N/” posts and from published Codex resets. “No post found” means we did not find a post for that day, not that nothing shipped. Campaign resets count toward Codex resets; improvements do not.
