Headliners

Codex CLI 0.163.0 (Oct 15). You can now send a follow-up while Codex is still responding to steer it mid-turn. A searchable /config screen, a configurable leader key in /keymap, and parallel execution of independent read-only tools (skills, memory and history lookups) also landed. Directory entry
Chrome DevTools MCP 1.11.0 (Oct 15). Adds screencast tools that need no ffmpeg and are on by default, a new heap-snapshot context analysis tool with pagination for snapshot comparisons, a flag to reject file: navigations, and config-file discovery with live reload. Lighthouse audits now return failing audits inline. Directory entry
FastMCP 4.1.0 (Oct 8). Mostly a fix sweep across OpenAPI, proxies, auth, tasks and the CLI, plus Python 3.15 support. Read the notes before upgrading: some security fixes are stricter (OpenAPI path params reject ./.., skill files must stay inside their directories, and HTTP sessions now expire after 30 idle minutes). Directory entry

Coding agents

Claude Code v2.1.301 (Oct 15) adds a cap on how long unattended retry mode waits on a usage limit, the % bracket-matching motion in vim mode, and richer OpenTelemetry fields that tell auto-mode classifier decisions apart from permission rules. Entry
OpenClaw 2026.10.4 is a stability patch: the Gateway survives sleep and clock jumps, shutdown no longer hangs, and an owner-impersonation path in Tlon group DMs was closed. Update if you self-host. Entry
Hermes Agent v0.22.2 (Oct 15) replaces v0.22.1, which was built from the wrong commit. It fixes gateways that refused to start after a reboot and makes long local-model turns more robust on laptops. Entry
goose v1.54.0 (Oct 8) adds HTML session export with an interactive viewer and a goose-mode prompt during first-time setup. Entry
Qwen Code v0.25.2 (Oct 15) ships more managed-agent team plumbing and TypeScript authoring for headless Mods. Entry
Also shipped: Kilo Code v7.8.12, Cline v4.1.24, Crush v0.98.1 and OpenCode v2.0.30.

MCP servers & SDKs

GitHub MCP Server 2.0.2 (Oct 8): bugfix that restores typed HTTP header validation for tools. Entry
Context7 MCP 4.4.2 (Oct 15) now advertises a server title and icons during the MCP handshake, so clients that show server branding display it properly. Entry
MCP TypeScript SDK 2.3.1 / 1.32.1 (Oct 5): maintenance releases on both the v2 and v1 lines. Entry

Frameworks & infra

OpenAI Agents SDK v0.24.0 (Oct 15) exposes MCP tool annotations on converted tools and adds run-wide tool-exception formatting. Entry
Browser Use 0.13.12 (Oct 15) adds OpenAI browser tools backed by Browser Use, working with local browsers, Browser Use Cloud or an existing session. Entry
Mastra 1.34.2 and new LangGraph package releases (prebuilt 1.1.1, CLI 0.4.35, Postgres checkpointer 3.2.0) kept the framework layer busy. Mastra · LangGraph

One thing to try

If your agent edits frontend code, give it Chrome DevTools MCP next to Playwright MCP. Playwright handles driving the page; DevTools lets the agent read console errors, network waterfalls and performance traces, so it checks its own work instead of asking you for screenshots.
