Claude Report — 2026-09-15

🚀 Anthropic Official

Claude Code v2.1.271 (Sep 14)

A large release: adds fast mode support to Claude Code Remote sessions (cloud and self-hosted runners), adds per-command allowed_domains to Bash/PowerShell/Monitor in auto mode with sandboxing, adds omitClaudeMd to agent frontmatter so subagents can skip CLAUDE.md files, adds --accept-command <sha256> to plugin install/update, and adds mouse support to the /config panel. Also ships a multiplier (up to 10x) for managed pricing settings, fixes MCP OAuth client-registration handling and list_changed-notification CPU spikes, fixes a stale .git/config.lock breaking git after a sandboxed command failure, and dozens of terminal, VS Code, Slack, and cloud-session fixes.

Claude Code v2.1.272 (Sep 15)

Ships as "bug fixes and reliability improvements" with no itemized changelog, following the previous day's feature-dense release.

claude-agent-sdk-typescript v0.3.270 → v0.3.272 (Sep 12–15)

Tracks Claude Code version-for-version: v0.3.270 reaches parity with v2.1.270, v0.3.271 adds omitClaudeMd to AgentDefinition and fixes session lookups on Windows mapped/SUBST drives, and v0.3.272 reaches parity with v2.1.272.

claude-agent-sdk-python remains frozen at v0.2.152 (Sep 2) — now 13 days stale, while the TypeScript SDK has shipped three more releases in that span with no package update on the Python side.

🔌 Claude Code Plugins

Plugin tracking skipped this run — official marketplace install-count cache unavailable.

Unchanged in window: n/a (tracking skipped). The claude-plugins-official repo shows only automated version bumps on Sep 14 (Dynatrace, Wix, Vercel, Stripe, ClickHouse, and five others) — routine maintenance, not part of the tracked top-10.

🛠️ Skills

tt-a1i/archify

Fixes diagnostics receipts getting truncated when piped, and rejects malformed visual-defect lists before they reach a benchmark run, in its agent-facing architecture-diagram compiler skill (Sep 15).

Unchanged in window: K-Dense-AI/scientific-agent-skills (only an automated security-scan commit since Sep 13, already reported), ayghri/i-have-adhd (no commits since Sep 14, already reported), affaan-m/ECC (no commits since Sep 12, already reported), agentskillexchange/skills (only automated sync-bot regeneration commits).

🤖 Agents & Subagents

nicobailon/pi-subagents v0.68.0

Tags a new release gating inspector and project-opening actions behind authority policy, fixing watchdog-scope loss on context compaction, and avoiding redundant intermediate wake-ups for workflow child agents (Sep 15).

Unchanged in window: VoltAgent/awesome-claude-code-subagents (no commits since Sep 14, already reported), anthropics/commerce-agents (no commits since Aug 31). See Anthropic Official above for anthropics/claude-agent-sdk-typescript (now v0.3.272) and anthropics/claude-agent-sdk-python (still v0.2.152).

🔗 MCPs & Integrations

oraios/serena

Splits its license into components: the core Serena application moves to GPL-3.0-or-later while the SolidLSP language-server layer stays MIT (Sep 14).

DeusData/codebase-memory-mcp

Lands a 7-commit memory-optimization pass — an MSan-safe spill store, a dedicated worker heap, and thread-locale cleanup at exit — to keep the server within its 15 GB memory budget (Sep 14).

upstash/context7

Ships a version-packages release and disables unused MCP subscriptions to cut connection overhead (Sep 14).

ChromeDevTools/chrome-devtools-mcp

Fixes config coercion dropping raw values, corrects documented defaults for non-boolean options, stops logging Puppeteer output to file unless requested, and migrates tests off a deprecated mock-context helper (Sep 14–15).

Unchanged in window: github/github-mcp-server (still v1.12.1, Sep 8).
