- Renamed `/fork` to `/branch` (`/fork` still works as an alias)
- [VSCode] Improved plan preview tab titles to use the plan's heading instead of "Claude's Plan"

- Added support for marketplace git URLs without `.git` suffix (Azure DevOps, AWS CodeCommit)
- Improved marketplace clone failure messages to show diagnostic info even when git produces no stderr
- Fixed several plugin issues: installation failing on Windows with `EEXIST` error in OneDrive folders, marketplace blocking user-scope installs when a project-scope install exists, `CLAUDE_CODE_PLUGIN_CACHE_DIR` creating literal `~` directories, and `plugin.json` with marketplace-only fields failing to load
- Fixed feedback survey appearing too frequently in long sessions

## 2.1.71

- Added `/loop` command to run a prompt or slash command on a recurring interval (e.g. `/loop 5m check the deploy`)
- Added cron scheduling tools for recurring prompts within a session
- Added `voice:pushToTalk` keybinding to make the voice activation key rebindable in `keybindings.json` (default: space) — modifier+letter combos like `meta+k` have zero typing interference

- Fixed prompting for `cd <cwd> && git ...` on Windows when the model uses a mingw-style path
- Improved startup time by deferring native image processor loading to first use
- Improved bridge session reconnection to complete within seconds after laptop wake from sleep, instead of waiting up to 10 minutes
- Improved `/plugin uninstall` to disable project-scoped plugins in `.claude/settings.local.json` instead of modifying `.claude/settings.json`, so changes don't affect teammates
- Improved plugin-provided MCP server deduplication — servers that duplicate a manually-configured server (same command/URL) are now skipped, preventing duplicate connections and tool sets. Suppressions are shown in the `/plugin` menu.
- Updated `/debug` to toggle debug logging on mid-session, since debug logs are no longer written by default
- Removed startup notification noise for unauthenticated org-registered claude.ai connectors

## 2.1.70

- Fixed API 400 errors when using `ANTHROPIC_BASE_URL` with a third-party gateway — tool search now correctly detects proxy endpoints and disables `tool_reference` blocks
- Fixed `API Error: 400 This model does not support the effort parameter` when using custom Bedrock inference profiles or other model identifiers not matching standard Claude naming patterns
- Fixed empty model responses immediately after `ToolSearch` — the server renders tool schemas with system-prompt-style tags at the prompt tail, which could confuse models into stopping early

- Fixed feature flags read during early startup never refreshing their disk cache, causing stale values to persist across sessions
- Fixed `permissions.defaultMode` settings values other than `acceptEdits` or `plan` being applied in Claude Code Remote environments — they are now ignored
- Fixed skill listing being re-injected on every `--resume` (~600 tokens saved per resume)
- Fixed teleport marker not rendering in VS Code teleported sessions
- Improved error message when microphone captures silence to distinguish from "no speech detected"
- Improved compaction to preserve images in the summarizer request, allowing prompt cache reuse for faster and cheaper compaction

- Reduced startup memory by ~426KB for users without custom CA certificates
- Reduced Remote Control `/poll` rate to once per 10 minutes while connected (was 1–2s), cutting server load ~300×. Reconnection is unaffected — transport loss immediately wakes fast polling.

- Fixed voice space bar getting stuck after a failed voice activation (module loading race, cold GrowthBook)
- Fixed worktree file copy on Windows
- Fixed global `.claude` folder detection on Windows
- Fixed symlink bypass where writing new files through a symlinked parent directory could escape the working directory in `acceptEdits` mode

- Improved macOS startup by eliminating redundant settings-file reloads when managed settings resolve
- Improved macOS startup for Claude.ai enterprise/team users by skipping an unnecessary keychain lookup
- Improved MCP `-p` startup by pipelining claude.ai config fetch with local connections and using a concurrency pool instead of sequential batching
- Improved voice startup by removing imperceptible warmup pulse animations that were causing re-render stutter
- Improved MCP binary content handling: tools returning PDFs, Office documents, or audio now save decoded bytes to disk with the correct file extension instead of dumping raw base64 into the conversation context. WebFetch also saves binary responses alongside its summary.

- Improved LSP tool rendering and memory context building to no longer read entire files
- Improved session upload and memory sync to avoid reading large files into memory before size/binary checks
- Improved file operation performance by avoiding reading file contents for existence checks (6 sites)

- Fixed a memory leak where MCP server fetch caches were not cleared on disconnect, causing growing memory usage with servers that reconnect frequently
- Improved memory usage in long sessions with subagents by stripping heavy progress message payloads during context compaction
- Added "Always copy full response" option to the `/copy` picker. When selected, future `/copy` commands will skip the code block picker and copy the full response directly.

- Added `CLAUDE_CODE_ACCOUNT_UUID`, `CLAUDE_CODE_USER_EMAIL`, and `CLAUDE_CODE_ORGANIZATION_UUID` environment variables for SDK callers to provide account info synchronously, eliminating a race condition where early telemetry events lacked account metadata.
- Fixed slash command autocomplete crashing when a plugin's SKILL.md description is a YAML array or other non-string type
- The `/model` picker now shows human-readable labels (e.g., "Sonnet 4.5") instead of raw model IDs for pinned model versions, with an upgrade hint when a newer version is available.

- Fixed a bug where bold and colored text in markdown output could shift to the wrong characters on Windows due to `\r\n` line endings.
- Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (anthropics/claude-code#26188)
