# Claude Code v2.1.319

> Claude Code v2.1.319, released 6 Nov 2026 (2026-11-06). 480 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

[Web version](https://changelogs.core-directive.com/v/2.1.319)

You can now load claude.ai connectors while signed in with an API key by setting CLAUDE_CODE_I_ACCEPT_CROSS_ORG_DATA_RISK. Claude Code shows a warning when you do this. On macOS, setting CLAUDE_CODE_NATIVE_APP_BUNDLE lets the native updater install Claude Code as a signed claude.app bundle. A new takesMcpToolHooksOnConnectors setting lets MCP tool hooks run on connector servers. In-process SDK MCP servers marked as modern now connect by skipping the setup handshake. This release has 480 entries, and 330 of them are usable today.

There are 13 entries in the build that are not switched on yet. Giving claude.ai connector tools a local file path, so Claude Code uploads the file itself, is off by default. A rewind for pending turns sits next to the Esc take-back handling, but its actions do nothing yet. Claude Code can tell the model which Claude app your message came from, such as iOS, Android, desktop or web. Reusing earlier messages to keep the prompt cache intact is controlled by CLAUDE_CODE_NORMALIZE_PREFIX_CACHE. Several new server-controlled switches arrive, including ones for Projects write warnings and Chrome tool recognition.

/autofix-pr now always starts a cloud session. Plugins that call ui.backdrop will break, because that method is gone. Many SDK session-control methods are removed, including the sign-in, MCP server and plugin reload ones. Claude in Chrome no longer offers shortcuts_list or shortcuts_execute for running browser shortcuts. Auto-compact now counts some failures separately, so it gives up less quickly. Refusals caused by an old credential no longer trigger retries.
