Under the hood
Terminal and desktop UI component allowlists drop raw HTML tags; terminal gains a "Client" component
What
The list of components allowed to render in the terminal interface no longer includes the raw HTML-like tags "div", "span", and "b"; the desktop list also drops these. The terminal list gains a new "Client" component.
Why
This tightens what can be rendered in these interfaces, likely closing off generic HTML-style tags in favor of a more controlled, named set of components such as the new "Client" one.
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added since
A small documentation edit on Claude apps gateway deployment and operations touched a line naming Client after this was published.
See [where each mechanism stores the policy](/docs/en/managed-settings#where-each-mechanism-stores-the-policy) for the file paths, and [Client-side managed settings](/docs/en/claude-apps-gateway-config#client-side-managed-settings) for the…claude-apps-gateway-deploy see the edit
Confirmed since
Anthropic's documentation has since written up Client, on List Events.
The judgement's grounds in registry-bound terms, for client branching and audit rather than end-user display. Open registry; currently "indeterminate" (no judgement was reached). Clients must tolerate values outside this set.api/beta/sessions/events/list see the edit
