Snapping, and a ready-made component for every major framework.

• snap: a scroller with scroll-snap-type glides to the snap points its CSS sets. The wheel moves as far as it would and the glide rests on the nearest point; with mandatory, one notch or one trackpad swipe moves one point. scrollTo and same-page links rest on the nearest point. scroll-padding, scroll-margin, scroll-snap-stop, areas longer than the visible area and snap points inside components are honoured, and every rest is where the browser itself would let the scroller rest.
• Components: Vue and Nuxt (/vue), Svelte and SvelteKit (/svelte), Solid (/solid), Angular (/angular) and Astro (/astro, view transitions included). Each renders on a server and is tested on the oldest version of its framework it supports.
• Examples for Vue, Nuxt, SvelteKit, Solid, Angular and Astro; Nuxt, SvelteKit and Angular render on the server. CI now builds every example from the packed package with its framework's own tool, serves it as its framework does and drives it in a browser (examples), and runs each component on its oldest supported framework (oldest frameworks).
• Installing Svifa in a Yarn Plug'n'Play project no longer turns on Yarn's experimental ES module loader: the package is "type": "commonjs", dist/package.json marks the built ES modules, every file keeps its name, and each framework entry imports the core from the file beside it.
• CodeQL runs from a workflow of the repository's own (.github/workflows/codeql.yml), on the same pinned runner as CI.
• React: a prop taken off SmoothScroll goes back to its default.
• The README's size figure is measured (about 10 kB minified and gzipped) and a test keeps it true; SECURITY.md says how to verify the signed release tags that start with 1.2.0.
