Lead

The headline is what ships July 22, not today. Python SDK v0.116.0 and TypeScript SDK v0.110.0 both landed July 2 with support for a new beta header: agent-memory-2026-07-22. Anthropic names its beta headers by activation date. Agent memory for Managed Agents arrives in three weeks. The SDKs are ready.

Claude Code v2.1.199 shipped the same evening. Stacked slash-skills (up to five), partial-response recovery on mid-stream failures, a Linux daemon bug that had been killing the background-agent process on unclean shutdown. Reliability work. The kind that lets the bigger features stay standing.

CODE

Claude Code v2.1.199

Stability sprint. Stacked slash-skill invocations now load all leading skills, up to five: write /skill-a /skill-b your prompt and both load. SSL certificate errors now surface actionable guidance immediately rather than burning retries. Partial streaming responses are preserved on mid-stream API errors rather than discarded. Fixed subagents silently swallowing rate-limit and server errors; partial work now returns to the parent. Fixed background-agent daemon on Linux killing itself after unclean shutdown. Fixed cold-start failures for background agents on macOS over SSH. Fixed claude stop being undone by background-agent respawn.

How to use claude update or reinstall. Stacked skills: /skill-a /skill-b your prompt
