+- ([#12180](https://github.com/quarto-dev/quarto-cli/issues/12180): Typst schema / autocomplete for `logo` option has `path` and `alt`.
 - ([#12554](https://github.com/quarto-dev/quarto-cli/pull/12554)): CSS properties `font-weight` and `font-style` are translated to Typst `text` properties.
 - ([#12695](https://github.com/quarto-dev/quarto-cli/issues/12695)): Resolve Typst `font-paths` that start with `/` relative to project root.
 - ([#12739](https://github.com/quarto-dev/quarto-cli/pull/12739)): Remove unused variable `heading-background-color` and `heading-decoration` from Typst's templates. They are leftover from previous change, and not part of Brand.yml schema for typography of headings.
