AI digest: 2026-10-22

Highlights

• stalemap: a new MIT plugin and MCP server that tells your coding agent which npm dependencies changed after its training cutoff. Install with /plugin marketplace add Umair/stalemap, then /plugin install stalemap@stalemap.
• Claude Code 2.1.307: /claude-api api-version migrates your Claude API code to the new API version. A claude_code.safety_event OpenTelemetry event records every blocked or prompted tool call, and @claude review stop ends always-on Code Review.
• Claude API version 2026-10-21: new SDK majors (Python 2.0, TypeScript 1.0, and others) remove temperature, top_p, and top_k, send keys as Authorization: Bearer, and switch to Apache 2.0. Check your code and gateways before upgrading.
