Sunday held all the way to the sweep.

Anthropic’s news page last updated May 19 with the KPMG global alliance. All docs endpoints (api, claude-code, claude-apps) returned 403 on direct fetch throughout this sweep. Claude Code sits at v2.1.150 (May 23): an infrastructure-only release, no user-facing changes. The substantive v2.1.149 drop (four security patches, /usage cost breakdown, /diff keyboard navigation) was covered in the May 22 sweep. Project Glasswing’s 10,000-bug milestone posted Saturday and is in the May 23 sweep.

SDK releases: Python SDK closed the week at v0.104.1 (May 22), a streaming fix for encrypted_content through the beta compaction accumulator. TypeScript SDK at sdk-v0.98.0 (May 21), thinking-token-count beta for streaming deltas.

No model announcements. No detectable API changes. The pace this year has been one Claude Code release every 24 to 48 hours on weekdays. Sunday is the pause.
