●CLI — Claude Code v2.1.259 landed on September 2. It is a dense release focused on org-wide configuration, unattended runs, and permissions — the most practically useful one this week●MCP — A new managedMcpServers setting lets an organization push HTTP/SSE MCP servers to every user. At the same time allowedMcpServers narrowed in scope, so an allowlist no longer filters managed servers out●HEADLESS — The new --permission-prompts none flag denies anything that would prompt, while the active permission mode, auto included, keeps making its own calls. Useful for anything you run unattended●SECURITY — Bash Read() deny rules had gaps: files passed as option values such as --ignore-revs-file=.env, and compounds like cd DIR && cat FILE, slipped past them. Both are now covered●SLACK — Claude Tag no longer judges messages one at a time. It reads the whole channel, along with its memory and your standing instructions, and is roughly 30% better at staying out of conversations●LEARN — Claude Academy is open. It is a free learning hub built on the 4D AI Fluency Framework that Anthropic uses to onboard its own team, with completion tracked in your Claude profile●CLI — Claude Code v2.1.259 landed on September 2.
