Claude Code just shipped 278 changes in 2 days (2.1.299 + 2.1.300) 7 updates you'll actually want to know. Bookmark this. 1. Walk away from a 200K+ token session and it auto-compacts before the cache expires, so you don't pay to reprocess everything. 2. /usage now warns you what's eating your limits. 3. Background agents and scheduled tasks stop double-firing. 4. Sandbox escape holes patched. 5. Files and photos from your phone via Remote Control finally arrive reliably. 6. Exit now force-kills stuck background commands. 7. Claude in Slack can ask "Allow once / Deny" instead of refusing.
