Claude Code v2.1.232 发布：Subagent Forking 默认开启，强化安全与 GitLab 支持

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
