# Claude Code 2.1.121

Captured: 2026-05-10T16:27:28.332Z

- Added `alwaysLoad` option to MCP server config — when `true`, all tools from that server skip tool-search deferral and are always available
- Added `claude plugin prune` to remove orphaned auto-installed plugin dependencies; `plugin uninstall --prune` cascades
- Added a type-to-filter search box to `/skills` so you can find a skill in long lists without scrolling
- PostToolUse hooks can now replace tool output for all tools via `hookSpecificOutput.updatedToolOutput` (previously MCP-only)
- Fullscreen mode: typing into the prompt no longer jumps scroll back to the bottom after you've scrolled up to read earlier output
- Dialogs that overflow the terminal are now scrollable with arrow keys, PgUp/PgDn, home/end, and mouse wheel in both fullscreen and non-fullscreen modes
- Clicking any line of a long URL that wraps across rows in fullscreen mode now opens the full URL
- SDK and `claude -p`: `CLAUDE_CODE_FORK_SUBAGENT=1` now works in non-interactive sessions
- `--dangerously-skip-permissions` no longer prompts for writes to `.claude/skills/`, `.claude/agents/`, and `.claude/commands/`
- `/terminal-setup` now enables iTerm2's "Applications in terminal may access clipboard" setting so `/copy` works, including from tmux
- MCP servers that hit a transient error during startup now auto-retry up to 3 times instead of staying disconnected
- The terminal tab session title is now generated in your configured `language` setting
- Claude.ai connectors with the same upstream URL are now deduplicated instead of appearing as duplicates
- Vertex AI: support X.509 certificate-based Workload Identity Federation (mTLS ADC)
- Faster startup after upgrading: removed the Recent Activity panel from the release-notes splash
- LSP diagnostic summaries now expand on click/ctrl+o and show the expand hint
- SDK: `mcp_authenticate` now supports `redirectUri` for custom scheme completion and claude.ai connectors
- OpenTelemetry: added `stop_reason`, `gen_ai.response.finish_reasons`, and `user_system_prompt` (gated behind `OTEL_LOG_USER_PROMPTS`) to LLM request spans
- [VSCode] Voice dictation now respects the `accessibility.voice.speechLanguage` setting when no Claude Code language is configured
- [VSCode] `/context` now opens a native token usage dialog
- Fixed unbounded memory growth (multi-GB RSS) when processing many images in a session
- Fixed `/usage` leaking up to ~2GB of memory on machines with large transcript histories
- Fixed memory leak when long-running tools fail to emit a clear progress event
- Fixed Bash tool becoming permanently unusable when the directory Claude was started in is deleted or moved mid-session
- Fixed `--resume` crashing on startup in external builds
- Fixed `--resume` failing on large sessions when a transcript line was corrupted by an unclean shutdown — the corrupt line is now skipped
- Fixed `thinking.type.enabled is not supported` error when using Bedrock application inference profile ARNs
- Fixed Microsoft 365 MCP OAuth failing with duplicate or unsupported `prompt` parameter
- Fixed scrollback duplication when pressing Ctrl+L or triggering a redraw in non-fullscreen mode on tmux, GNOME Terminal, Windows Terminal, and Konsole
- Fixed claude.ai MCP connectors silently disappearing when the connector-list fetch hits a transient auth error at startup
- Fixed "Always allow" rules for built-in tools in remote sessions not surviving worker restarts
- Fixed `NO_PROXY` not being respected for all HTTP clients when set via `managed-settings.json` under the native build
- Fixed managed settings approval prompt exiting the session even when accepted — now applies settings and continues
- Fixed `/usage` returning "rate limited" after a stale OAuth token — now refreshes automatically
- Fixed invalid legacy enum values in `settings.json` invalidating the entire settings file
- Fixed `/usage` dialog content being clipped when no-flicker mode is off
- Fixed `/focus` showing "Unknown command" when the fullscreen renderer is off — now explains how to enable it
- Fixed embedded grep/find/rg shell wrappers failing when the running binary is deleted mid-session — now falls back to installed tools
- Reduced peak file descriptor usage during `find` in the Bash tool on large directory trees
