Anthropic’s official Claude Code changelog lists version 2.1.224 in the August 7, 2026 update, with several changes aimed at long-running and remotely managed agent sessions.

Self-hosted environments
Claude Code now includes claude self-hosted-runner, which lets organizations use their own machines or containers as the place where Claude Code web, mobile, and desktop sessions run. The changelog says this is available on Team and Enterprise plans.
That gives teams a way to keep execution in infrastructure they control while still using Claude Code’s connected session surfaces. The changelog entry does not specify all deployment or networking requirements, so teams should follow Anthropic’s current self-hosted-runner documentation before planning an implementation.
Sessions can message each other
The release adds cross-session SendMessage support: Claude Code sessions can message one another across a user’s machines, with ListAgents available to discover sessions. The same update adds crossSessionInbound and dialogExpiry settings so messages sent to sessions running with bypassed permissions can be held for approval, while messages to other sessions can auto-deliver.
These controls matter for multi-agent workflows because the new capability is not just a notification channel. It creates a way for long-running sessions to coordinate, while keeping an approval boundary for higher-risk permission modes.
Other notable changes
The 2.1.224 entry also lists:
- An
archiveplugin source for installing plugins from HTTPS zip files, with optional SHA-256 pinning - New sandbox credential-masking options, including JWT claim masking and AWS SigV4 re-signing
- Removal of the 200-subagent-per-session spawn cap, while concurrency and depth limits still apply
- Fixes for long project paths, sandbox deny entries, MCP tools connecting mid-turn, and Remote Control reconnect behavior
