## What's changed
- Subagent forking is now on by default: a `subagent_type: "fork"` subagent inherits the full conversation and prompt cache, and non-teammate agent spawns in interactive sessions now run in the background by default
- Type `@` in the prompt to mention another Claude session by name; Claude then uses `SendMessage` to reach that session directly
- `SendMessage` now delivers to a bare name that exactly matches one live session, instead of asking to confirm with a ref first
- Interactive sessions on one machine now keep unique names: starting or renaming a session to a name another live session already uses gives it a `name-word-word` variant and tells you
- Added `/config` rows for "Dialog expiry" and "Messages from your other sessions" (cross-session inbound accept/hold/refuse)
- Added secret redaction for GitLab token families (`glrt-`, `gloas-`, `glptt-`, `glagent-`, `glimt-`, `glsoat-`, `glcbt-`, `glft-`, `glffct-`) and full redaction of routable `glpat-`/`gldt-` tokens; the `glab` CLI config store gets the same sandbox and credential-path protection as `gh`
- Added GitLab support to plugin marketplaces: bare `gitlab.com` repo URLs (including nested subgroups) now clone like `github.com` URLs, and clone auth-failure hints name your actual git host
- Settings: `additionalMarketplaces` and `allowedMarketplaces` are now accepted as friendlier aliases for `extraKnownMarketplaces` and `strictKnownMarketplaces`
- Enterprise policy: a url-typed `blockedMarketplaces` entry for a bare repo URL keeps blocking that URL when the CLI classifies it as a git clone
- Gateway: the `desktop:` overlay now accepts every released Desktop setting (was 11 hand-listed keys), validated at boot against Desktop's own schema; unknown or invalid keys fail boot
- Gateway: empty `managed.policies[].match.groups`/`admin.admin_groups` entries and malformed `email_domain` values (empty, or containing `@`, whitespace, or commas) now fail at boot instead of silently matching no one or granting admin access
- Fable 5 is offered as an advisor in `/advisor` again for organizations with Fable access, with usage-credits consent set up through `/model fable`
- Fixed a PowerShell permission bypass where variable-writing parameters could silently overwrite `$PSDefaultParameterValues` and redirect later commands' file access
- Fixed a Windows permission bypass where Git Bash followed Cygwin-style symlinks that path validation saw as regular files; writes through them now require permission approval
- Fixed nested git repositories inheriting trust from a parent directory; each repository now requires its own trust confirmation
- Fixed MCP connections hanging for the full 30-second connect timeout when a server fails to answer or sends a malformed reply to the protocol-version probe
- Fixed Remote Control sessions hosted by a bridge inside a cloud session inheriting that session's transcript or credentials
- Fixed Remote Control sessions started from Claude Desktop or an IDE appearing as a new claude.ai session each time the local session was resumed; they now reattach to the existing one
- Fixed Remote Control sessions appearing unreachable to newly attached clients while idle
- Fixed Remote Control bridge sessions not restoring conversation history when the session worker restarts
- Remote Control: resuming a conversation whose session was deleted from claude.ai or the app now starts a replacement instead of failing with a message about your login (regressed in v2.1.227)
- Fixed Cloud gateway `/login` exiting silently or leaving an unresponsive terminal after "Press Enter to continue" when managed settings failed to load; the reason is now shown
- Fixed voice mode on native builds getting stuck on "listening…" when the voice service rejected the connection; the rejection is now shown immediately
- Fixed mTLS client certificate rotation requiring a restart; Claude Code now reloads the rotated cert and key automatically on connection errors
- Fixed malformed AWS or Vertex region values being used to build request URLs; they now fall back to the default region
- Fixed stream idle timeout errors failing the request instead of recovering on Bedrock, Vertex, and gateway deployments
- Fixed content-sized overlays containing truncated text rendering one column too wide, and start-truncated text collapsing to an ellipsis
- Fixed a stray garbled character where a long shell-command or agent-description preview was cut off mid-emoji
- Fixed a startup race that could silently unregister a plugin marketplace due to concurrent writes to `known_marketplaces.json`
- Fixed `/update` and `/tui` refusing to restart while work that survives the relaunch was running
- Fixed usage-limit guidance suggesting unavailable slash commands in SDK and remote sessions
- Fixed the consent message for interactive `--advisor fable` launches, which told you to run `/model fable` in an interactive session that had just exited
- Improved fullscreen streaming: long sessions stay responsive because the whole conversation is no longer re-normalized on every update
- Improved the managed settings approval dialog: shows endpoint URLs, uses clearer wording for telemetry-only changes, skips routine OpenTelemetry options, and requires approval for server-managed sandbox binary overrides (`sandbox.bwrapPath`, `sandbox.socatPath`, `sandbox.ripgrep`)
- `/feedback` and `/bug` now open immediately when invoked while Claude is responding, instead of waiting for the turn to finish
- `/plugin install plugin@marketplace` now refreshes the marketplace first, so newly published plugins install without a manual marketplace update
- `/code-review` at high, xhigh, and max effort now runs in a background agent like the other levels
- Pasted and clipboard images are read without blocking the event loop
- Remote Control now keeps reconnecting for about 30 minutes after a network blip and no longer drops after a few blips spread across an hour
- Remote Control: resuming a conversation no longer silently takes Remote Control away from another Claude Code on the same machine that still has it; run `/remote-control` there to move it
- Updated agent panel: completed subagents hide immediately with a `/tasks` footer hint, and the "↓ N more" overflow indicator moved left for visibility
- Remote Control: the terminal now says whether a session was taken over by another device, ended from another app, or deleted, and stops suggesting a reconnect that would undo it
- Bash input redirections (`< file`) are now permission-checked like their argument spellings on all platforms
- Shortened the message shown when resuming a completed background agent
- Cowork sessions no longer inline external @-imports from user-scope memory files
- Hardened the auto-generated cross-session messaging socket directory on shared `/tmp`: a pre-planted symlink or another user's directory is now refused instead of used
- Hardened the Linux filesystem sandbox against a protected-path bypass
- Changed `sandbox.ripgrep` to be honored only from user, managed, and `--settings` settings; project settings can no longer override the sandbox's ripgrep binary
- Removed the startup tip suggesting you create custom subagents, and the matching nudge in the `/powerup` tour
