What changed, and when.

Every released version of the prism extension, and what each one changed.

fix: Raise quarto-required to >=1.9.38. The extension manifest registers the filter at pre-ast, and the _extension.yml schema only accepts a filter entry point from that version; below it the render fails validation.
fix: Leave the typst: attributes Pandoc reads itself untouched in a Typst render, rather than stripping their prefix and losing the styling. On a div those are typst:text:<property> and the thirteen parameters of Typst’s block(): width, height, breakable, fill, stroke, radius, inset, outset, spacing, above, below, clip, and sticky. On a span only typst:text:<property> is read, and on a code block or a heading nothing is, so prism keeps those. The reserved keys now work alongside a promoted typst:style on the same element, and the split follows Typst property output. Applies whenever Pandoc writes Typst, including under a custom format.

docs: Add a documentation website under docs/, built on the atelier project type and published to https://m.canouil.dev/quarto-prism/, with a Typst rendering of the same source so both branches of a prefix can be compared.
docs: Trim README.md to a landing page pointing at the website, and example.qmd to a short starting point to copy.
docs: Add the Pages workflow, which renders docs/ on pull requests and deploys it from the release tag.
docs: Add the Quarto Extensions Updates workflow, scanning docs for the website’s own dependencies.

fix: move lua filter to pre-ast to ensure it runs before any filters (e.g., cascade).

feat: Resolve format-prefixed attributes on headings (## Heading {html:style="..."}), matching the existing behaviour on Div, Span, and CodeBlock elements.

feat: Add the extensions.prism.warn-on-drop option (default false) which emits a quarto.log.warning each time a format-scoped attribute is dropped because no prefix matched the active target format; useful to surface typos in prefixes that would otherwise vanish silently.

docs: Document the final attribute output order (kept then promoted, source-order tiebreak) and the behaviour of unknown prefixes (treated as non-matching and dropped).
docs: Add an explicit precedence table (exact > alias > default > unprefixed) and a worked example for the conflict case where a static unprefixed value coexists with format-scoped and default values for the same attribute name.

refactor: Extract the HTML slide-format set into the shared _modules/slide-formats.lua module so prism and portable-links agree on what counts as a slide format; the canonical source lives in mcanouil-skills/skills/creating-quarto-extension/assets/modules and is copied into each extension on release.

feat: Add the slide format-group alias, which matches every HTML slide format (revealjs, slidy, s5, dzslides, slideous), so a single prefix can target the whole group.
feat: Add the default:name fallback prefix, applied only when no format-specific variant of the same attribute name matched the active format.

feat: Initial release of the prism filter, promoting format:name attributes on Div, Span, and CodeBlock elements when the prefix matches the active rendering format.
