What's new in Claude Code, August 2026
Claude Code adds self-hosted runners, cross-session @ mentions and a --restricted mode
Claude Code's August 2026 releases added self-hosted environments, cross-session messaging and a --restricted mode. Twenty-eight releases shipped, from v2.1.221 to v2.1.252. claude self-hosted-runner (v2.1.224) lets Team and Enterprise plans run Claude Code web, mobile and desktop sessions on their own machines or containers, and later releases added flags such as --defer-shutdown-max-min and --client-label.
Sessions can now talk to each other: typing @ mentions another session by name, and subagent forking is on by default (v2.1.232). v2.1.248 added --restricted, which removes the built-in tools that run commands or code and WebFetch. Other additions include Focus view in VS Code, credential masking in the Linux and WSL sandbox, PreModelSwitch and PostModelSwitch hooks, and a Loops breakdown in /usage. Several releases tightened Bash permission checks, and a number were bug-fix-only.
