# Claude Code v2.1.292

> Claude Code v2.1.292, released 6 Oct 2026 (2026-10-06). 331 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

[Web version](https://changelogs.core-directive.com/v/2.1.292)

You can now name backup models in the new accessFallbackModels setting, for use when the main model can't be used. A new per-server disableAutoBackground option stops Claude Code from moving that MCP server's tool calls to the background. In remote sessions, CLAUDE_CODE_HOST_SKILL_CATALOG can list which skills are allowed to load. Setting CLAUDE_CODE_ARTIFACT_PREVIEW to false now turns artifact preview off. A new Publish plugin tool sends a plugin to your organization's library after you confirm. Organisations under the HIPAA policy are blocked from publishing plugins this way.

Several features are in the build but not switched on yet. An option for screen-reader users to move through suggestions with the arrow keys is built but held behind a remote switch that is off. WebFetch can ask about blocked URLs one prompt at a time, but only once a server switch is turned on. An emulator engine for artifact previews in remote sessions is built but cannot be selected yet. Plugin rating now also needs a server switch, and that switch defaults to off. Pressing Enter on a slash-command suggestion can run only the one you picked with the arrow keys, once that behaviour is switched on.

Composed characters and IME typing are no longer dropped from the prompt. In vim mode, h and l now stop at the start and end of a line. The vim f, t, F and T searches now stay on the current line. The ; and , keys now repeat the last vim search even when the character was not found. Web search in remote sessions no longer skips the proxy when web fetch is disabled. A slow-starting local MCP server is no longer wrongly remembered as an older server after a timeout.
