+          This PR adds or modifies `allowed_non_write_users`, which allows users without write access to trigger Claude Code Action workflows. This can introduce security risks.
+
+          If this is a new flow, please make sure you actually need `allowed_non_write_users`. If you are editing an existing workflow, double check that you are not adding new Claude permissions which might lead to a vulnerability.

 # Changelog
 
+## 2.1.56
+
+- VS Code: Fixed another cause of "command 'claude-vscode.editor.openLast' not found" crashes
+
+## 2.1.55
+
+- Fixed BashTool failing on Windows with EINVAL error
+
+## 2.1.53
+
+- Fixed a UI flicker where user input would briefly disappear after submission before the message rendered
+- Fixed bulk agent kill (ctrl+f) to send a single aggregate notification instead of one per agent, and to properly clear the command queue
+- Fixed graceful shutdown sometimes leaving stale sessions when using Remote Control by parallelizing teardown network calls
+- Fixed `--worktree` sometimes being ignored on first launch
+- Fixed a panic ("switch on corrupted value") on Windows
+- Fixed a crash that could occur when spawning many processes on Windows
+- Fixed a crash in the WebAssembly interpreter on Linux x64 & Windows x64
+- Fixed a crash that sometimes occurred after 2 minutes on Windows ARM64
+
+## 2.1.52
+
+- VS Code: Fixed extension crash on Windows ("command 'claude-vscode.editor.openLast' not found")
+
+## 2.1.51
+
+- Added `claude remote-control` subcommand for external builds, enabling local environment serving for all users.
+- Updated plugin marketplace default git timeout from 30s to 120s and added `CLAUDE_CODE_PLUGIN_GIT_TIMEOUT_MS` to configure.
+- Added support for custom npm registries and specific version pinning when installing plugins from npm sources
+- BashTool now skips login shell (`-l` flag) by default when a shell snapshot is available, improving command execution performance. Previously this required setting `CLAUDE_BASH_NO_LOGIN=true`.
+- Fixed a security issue where `statusLine` and `fileSuggestion` hook commands could execute without workspace trust acceptance in interactive mode.
+- Tool results larger than 50K characters are now persisted to disk (previously 100K). This reduces context window usage and improves conversation longevity.
+- Fixed a bug where duplicate `control_response` messages (e.g. from WebSocket reconnects) could cause API 400 errors by pushing duplicate assistant messages into the conversation.
+- 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.
+- Managed settings can now be set via macOS plist or Windows Registry. Learn more at https://code.claude.com/docs/en/settings#settings-files
+
 ## 2.1.50
 
 - Added support for `startupTimeout` configuration for LSP servers
