What probably matters to youSection of the release

The plan artifact template is bundled with no visible render site.

What

A new embedded HTML template for rendering plans as artifacts ships alongside the existing workshop templates, with a hardened sanitizer. Nothing in this build shows where the plan template gets rendered, so it may not be reachable yet.

Details
  • The sanitizer strips iframe, embed, object, base, form, link, noscript, frameset, frame, plaintext and the SVG animation elements.
  • Collected results use a list type that stops accepting entries past a cap and records an overflow marker instead of growing without bound.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
