| Version | Published | Note |
|---|---|---|
| v2.1.316 | October 31, 2026 | Added `CLAUDE_CODE_DISABLE_ULTRATHINK`, which turns the `ultrathink` keyword off |
| v2.1.314 | October 30, 2026 | Added `permissions.blockWritesOutsideWorkingDirectories`: Write, Edit and NotebookEdit refuse paths outside the working directories in every permission mode |
| v2.1.312 | October 27, 2026 | Added `oidc.user_id_claim` to the Claude apps gateway, to identify people by an id_token claim other than `sub`, such as Microsoft Entra ID's `oid` |
| v2.1.311 | October 26, 2026 | Added `--hold-idle-file` and `--max-hold-min` to `self-hosted-runner`, to keep an idle session while your host reports processes it left running |
| v2.1.310 | October 23, 2026 | Added the Monitor tool and plugin monitors on Bedrock, Vertex, and Foundry, and when telemetry or nonessential traffic is disabled; long foreground sleeps are now blocked there too |
| v2.1.309 | October 22, 2026 | Fixed sandboxed Bash commands on macOS and Linux running the shell's startup files outside the sandbox before each command |
| v2.1.308 | October 22, 2026 | Bug fixes and reliability improvements |
| v2.1.307 | October 21, 2026 | Added `/claude-api api-version` to move Claude API code to API version `2026-10-21` |
| v2.1.306 | October 21, 2026 | Fixed `claude -p` inside cloud sessions reporting "Not logged in" when started without the session's environment variables |
| v2.1.305 | October 20, 2026 | Added `sandbox.allowNestedUserNamespaces` so sandboxed commands on Linux can create user namespaces (Chromium, rootless podman); this lets them get around the sandbox's file protections |
| v2.1.304 | October 19, 2026 | Added a transcript line when a plugin that runs first skips one of your mod's hooks, naming the event and the plugin |
| v2.1.303 | October 18, 2026 | Bug fixes and reliability improvements |
| v2.1.302 | October 16, 2026 | Added `CLAUDE_CODE_AUTO_MODE_MODEL` to choose the model the client-side auto mode classifier uses; it does not change the model for server-side auto mode |
| v2.1.301 | October 15, 2026 | Added `CLAUDE_CODE_RETRY_WATCHDOG_MAX_USAGE_LIMIT_WAIT_MS` so unattended retry mode (`CLAUDE_CODE_RETRY_WATCHDOG`) ends a request at a usage limit that resets too far away instead of waiting |
| v2.1.300 | October 14, 2026 | Added `virtualText` to a mod's prompt decorations: text drawn in the prompt box that never enters the draft or the submitted prompt |
| v2.1.299 | October 14, 2026 | Added `CLAUDE_CODE_DISABLE_FILE_MENTIONS` environment variable: Claude gets the paths of `@` file mentions to read with its file tools, not the files' contents |
| v2.1.296 | October 9, 2026 | Added a `code` key to the Claude apps gateway's `managed.policies[]`: the same settings as `cli`, also applied in Claude Desktop's Code tab; beside `desktop`, it turns on Claude Desktop's gateway mode |
| v2.1.295 | October 8, 2026 | Added `onFailure: "block"` for command and HTTP hooks: a hook that can't start, times out, or exits with an unexpected code blocks the action instead of letting it through |
| v2.1.294 | October 8, 2026 | Fixed `prompt` and `agent` hooks written as instructions (such as "Block commands that...") allowing what they should block |
| v2.1.293 | October 7, 2026 | Added Claude Haiku 5.5 (`claude-haiku-5-5`), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K) |
| v2.1.292 | October 6, 2026 | Added `--marketplace <source>` to `claude plugin install`: adds the marketplace if needed, under the same policy checks as `claude plugin marketplace add`, then installs the plugin from it |
| v2.1.291 | October 6, 2026 | Fixed a regression in 2.1.290 where cloud sessions could drop answers to permission prompts |
| v2.1.290 | October 5, 2026 | Added `serverToolUses` to the result of a mod's `turn.step` hook: the tool calls the API ran itself (the advisor), each with its id, name, input, start and end |
| v2.1.289 | October 3, 2026 | Fixed a deny or ask rule on a nested part of a compound shell command not holding over a user-installed mod's approval on managed machines |
| v2.1.288 | October 2, 2026 | Added `$.ui.selection()` for mods: returns the text you last selected in fullscreen mode and, when the selection lies within one transcript row, that row |
| v2.1.287 | October 1, 2026 | Added Claude Mods: plugins may now modify deeper behavior |
