Lataa Claude Code 2.1.259

- Added managedMcpServers managed setting: organizations can provide HTTP/SSE MCP servers to every user (same entry shape as .mcp.json); entries that name a command to run are skipped
- Added --permission-prompts none for unattended headless hosts: anything that would prompt is denied automatically while the active permission mode (including auto mode) keeps deciding
- Added recognition of glab mr create/merge/close/reopen/note/update so GitLab merge requests show as MR !N in the collapsed tool summary and refresh the footer MR badge
- Added --json to claude plugin validate for a machine-readable validation report
- Fixed concurrent sessions silently reverting each other's ~/.claude.json changes — workspace trust no longer resets and MCP/project state is no longer lost when running many sessions at once
- Fixed a conversation whose thinking was rejected once being rejected again on every later turn
- Fixed Bash Read() deny rules not covering files given as option values (--ignore-revs-file=.env, -f.env, @file), git diff/git grep file operands, or cd DIR && cat FILE compounds; grep -r/cp -r over a directory holding a denied file now asks
- Fixed the prompt cache being invalidated when the OAuth token refreshed in sessions with telemetry disabled
- Fixed fullscreen mode showing a blank conversation after a long turn with hundreds of tool calls
- Fixed auto mode running a turn on a model it doesn't support when a command or skill's frontmatter model: named one; the turn now keeps the session model
- Fixed CLAUDE_CODE_MAX_CONTEXT_TOKENS being ignored for Vertex-style model IDs (@YYYYMMDD suffix) of model versions Claude Code doesn't recognize
- Fixed the live output preview of a running shell command hiding its newest lines when an earlier line wrapped
- Fixed a background GitHub connection check that ran on every launch for claude.ai users; the result is now remembered across launches
- Fixed --resume failing (and --continue opening an empty conversation) when a saved session contains an attachment entry with no payload
- Fixed frontmatter model: on custom commands and skills being ignored in interactive sessions
- Fixed Artifact publishing failing once with an "unexpected parameter note" error in conversations continued from an older version
- Fixed managed forceRemoteSettingsRefresh being ignored at startup when a policy helper configured by MDM or the managed settings file had already run
- Fixed worktree isolation refusing hook-created worktrees on machines where git rev-parse fails with a message other than "not a git repository"
- Fixed OpenTelemetry metrics and events from cloud sessions missing the user.email, organization.id, and user.account_uuid attributes
- Fixed MCP servers that disconnect while their tools are being listed at startup showing as connected with no tools instead of reporting the error
- Fixed the file edit permission dialog sometimes showing a changed line cut short with no indication
- Fixed repository detection dropping a known repo identity after a transient git probe failure
- Fixed managed settings silently going unenforced when the managed-settings file, a drop-in, the MDM plist, or the HKLM value cannot be parsed: Claude Code now refuses to start and names the source
- Fixed Stop not actually stopping background agents and workflows in remote-control sessions: killed tasks now stay visible and re-stoppable until their processes exit
- Fixed resuming a workflow run while its previous stopped run was still exiting, which could run duplicate copies of its agents
- Fixed marketplace repo URLs on github.com with a trailing slash or dangling ?/# producing an unusable .git clone URL
- Fixed blocking Stop hooks causing the turn after a block to lose the model's reasoning from that turn and, on some models, miss the prompt cache
- Fixed remote (claude.ai) sessions taking 60 seconds to start a turn after a browser-hosted MCP server's page had gone away
- Fixed worktree-isolated sessions refusing common Bash loops, xargs pipelines and launcher-wrapped commands that cannot reach the main checkout
- Improved terminal resize and first-render performance for long responses by reusing text measurements
- Improved /workflows agent detail: JSON outcomes are pretty-printed with syntax colors and real line breaks, and long outcomes fold behind an expand toggle
- Improved headless/SDK session start: the first turn begins up to 50 ms sooner when MCP servers finish connecting
- Improved /install-github-app to explain it is GitHub-only and point to the GitLab CI/CD docs when run inside a GitLab repository
- Improved nested background subagent results to be saved in the parent subagent's transcript, so resumed subagents keep them and shared transcripts show the delivery
- Changed allowedMcpServers to govern only servers users add: a literal managed-mcp.json server your allowlist used to filter out now loads on upgrade; use deniedMcpServers to keep it off
- [VSCode] Added an Active quick filter and a status filter menu (Needs input, Working, Completed) to the session list sidebar
- Fixed remote and scheduled sessions doing nothing after a connector-tool permission prompt was approved while the session was paused
