Claude Code v2.1.224を公開

What's changed

• Added self-hosted environments: claude self-hosted-runner turns your own machines or containers into a place Claude Code web, mobile, and desktop sessions can run, on Team and Enterprise plans

• Added archive plugin source: install plugins from a zip over HTTPS without git or npm, with optional SHA-256 pinning

• Added a cancel-and-confirm step when removing an unavailable paste changes a command's text

• Added ANTHROPIC_BEDROCK_REGION_PREFIX env var for Bedrock to prefer a specific cross-region inference profile over the AWS_REGION-derived one

• Added crossSessionInbound and dialogExpiry settings: cross-session messages sent to a session running with bypassed permissions are held for your approval, and messages to other sessions auto-deliver

• Added sandbox credential-masking options: extract and onExtractNoMatch for structured env values, decode: "jwt" with maskClaims for JWT-aware masking, and awsPairs/sigv4 for AWS SigV4 re-signing; these need network.tlsTerminate and are honored only from user, managed, or --settings settings

• Added cross-session SendMessage: Claude Code sessions can now message each other, on any of your machines, with ListAgents to discover them (macOS and Linux)

• Fixed long (>200 char) project paths resolving to another project's session directory under a shared sanitized prefix; session list, rename, fork, delete and /resume no longer cross projects

• Fixed SendMessage reporting "Message sent" when the write to a teammate's inbox had actually failed; failed deliveries are now reported as errors

• Fixed sandbox filesystem deny entries written with a trailing slash (e.g. denyRead: "~/.aws/") being silently bypassable on Linux and macOS

• Fixed sandbox violation details never appearing in Bash tool results; Claude now sees which file or network access was denied and why

• Fixed MCP tools that connect mid-turn being deferred for tool search without their names announced to the model

• Fixed plugin install records being silently corrupted when the same plugin is installed in multiple projects

• Fixed recalled or restored paste content occasionally attaching wrong data or silently losing text when the paste had aged out or placeholder numbers collided

• Fixed copy-on-select on Wayland sometimes not reaching the clipboard; the two selection writes no longer race

• Fixed the feedback survey's transcript share silently failing on long sessions; a failed share now shows an error instead of a success message

• Fixed Remote Control auto-start intermittently failing with "Remote credentials fetch failed" on a cold start with a stale login token

• Fixed Remote Control and SDK clients showing a blank "(no content)" message after /clear and other output-less commands

• Fixed a Remote Control session recreated after its server session expired uploading prior local conversation history into the new session

• Improved fullscreen mode to keep the full pre-compaction history in scrollback across repeated compactions, instead of only the most recent interval

• Improved Remote Control: attached web and mobile clients now see compaction progress and the post-compaction boundary instead of a silent pause; /clear resets now propagate to attached clients

• Improved Remote Control: connection failures now show a persistent failure indicator with details and a reconnect shortcut, instead of only an 8-second toast

• Removed the 200-subagent-per-session spawn cap; long-running sessions no longer refuse new agents (concurrency and depth limits still apply)

• Changed managed settings: the approval prompt no longer re-appears after re-login or org switching when the organization's settings are unchanged

• Changed the feedback-survey transcript share: with your consent it now also uploads the last request's model settings — the system prompt (which includes your CLAUDE.md instructions), tool definitions, and model parameters. Secrets are redacted as before, and these fields are dropped first if the share is too large

• Changed the Bash tool description to always note that command output is displayed to the model, not reliably to the user

• Changed recalled paste placeholder numbers to renumber when accepted into the input

• Changed Remote Control to archive the stale server session instead of leaving a dead one listed when a fresh session is minted after compaction or /resume

• [VSCode] Fixed the extension showing Remote Control as connected after the connection failed

• Fixed a session resume silently reconnecting Remote Control after the user turned it off (--resume, SDK hosts, and the VS Code extension)

• [VSCode] Fixed sessions not honoring remoteControlAtStartup when explicitly enabled
