ClaudeCodeLog · x · 2026-09-03
Full changelog for Claude Code CLI 2.1.259 (37 changes):
New features
- managedMcpServers managed setting: orgs can provide HTTP/SSE MCP servers to every user (same entry shape as .mcp.); command-running entries are skipped
- --permission-prompts none for unattended headless hosts: anything that would prompt is auto-denied while the active permission mode (including auto mode) keeps deciding
- Recognition of glab mr create/merge/close/reopen/note/update so GitLab merge requests show as MR !N with footer badge
- -- flag for claude plugin validate for machine-readable reports
Fixes
- Concurrent sessions no longer silently revert each other's /.claude. changes — workspace trust and MCP/project state persist across parallel sessions
