Resumed sessions stop rewriting your history
2.1.282 fixes continued and resumed sessions that were silently re-sending earlier messages in altered form — dropping extended thinking and quietly breaking prompt caching. Very large sessions also resume faster. Update if you have seen unexplained reasoning gaps or cache-miss cost spikes.
Auto mode goes server-side — and the overhead charge is gone
Recent releases switch auto mode to a server-side classifier by default on the Claude API, Enterprise, Bedrock, Vertex and gateways, with no extra classifier charges. Read-only and sandboxed shell commands now wait for that server-side review before running.
No CLAUDE.md? Claude Code now reads AGENTS.md
Claude Code falls back to AGENTS.md for project instructions when no CLAUDE.md is present — so a repo you already set up for Codex or other AGENTS.md tools works in Claude Code with zero extra config.
Cursor ships Rollouts and Security Review bots
Cursor added two PR bots. Rollouts watches deploys per environment and flags regressions through GitHub, CD systems and Datadog; Security Review scans PRs for injection, auth-bypass and other exploitable bugs, reporting severity and fixes. Both are on Teams and Enterprise with trial credits.
