## 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
