* runtime-first approach * revert these * type safety, lint * fix: better input cursor restoration for `bind:value` (#16925) If cursor was at end and new input is longer, move cursor to new end No test because not possible to reproduce using our test setup. Follow-up to #14649, helps with #16577 * Version Packages (#16920) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> * docs: await no longer need pending (#16900) * docs: link to custom renderer issue in Svelte Native discussion (#16896) * fix code block (#16937) Updated code block syntax from Svelte to JavaScript for clarity. * fix: unset context on stale promises (#16935) * fix: unset context on stale promises When a stale promise is rejected in `async_derived`, and the promise eventually resolves, `d.resolve` will be noop and `d.promise.then(handler, ...)` will never run. That in turns means any restored context (via `(await save(..))()`) will never be unset. We have to handle this case and unset the context to prevent errors such as false-positive state mutation errors * fix: unset context on stale promises (slightly different approach) (#16936) * slightly different approach to #16935 * move unset_context call * get rid of logs --------- Co-authored-by: Rich Harris <rich.harris@vercel.com> * fix: svg `radialGradient` `fr` attribute missing in types (#16943) * fix(svg radialGradient): fr attribute missing in types * chore: add changeset * Version Packages (#16940) * Version Packages * Update packages/svelte/CHANGELOG.md --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Rich Harris <rich.harris@vercel.com> * chore: simplify `batch.apply()` (#16945) * chore: simplify `batch.apply()` * belt and braces * note to self * unused * fix: don't rerun async effects unnecessarily (#16944) Since #16866, when an async effect runs multiple times, we rebase older batches and rerun those effects. This can have unintended consequences: In a case where an async effect only depends on a single source, and that single source was updated in a later batch, we know that we don't need to / should not rerun the older batch. This PR makes it so: We collect all the sources of older batches that are not part of the current batch that just committed, and then only mark those async effects as dirty which depend on one of those other sources. Fixes the bug I noticed while working on #16935 * fix: ensure map iteration order is correct (#16947) quick follow-up to #16944 Resetting a map entry does not change its position in the map when iterating. We need to make sure that reset makes that batch jump "to the front" for the "reject all stale batches" logic below. Edge case for which I can't come up with a test case but it _is_ a possibility. * feat: add `createContext` utility for type-safe context (#16948) * feat: add `createContext` utility for type-safe context * regenerate * Version Packages (#16946) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> * chore: Remove annoying sync-async warning (#16949) * fix * use `$state.eager(value)` instead of `$effect.pending(value)` --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: Hyunbin Seo <47051820+hyunbinseo@users.noreply.github.com> Co-authored-by: Ben McCann <322311+benmccann@users.noreply.github.com> Co-authored-by: Rich Harris <rich.harris@vercel.com> Co-authored-by: Hannes Rüger <hannes@hannesrueger.de> Co-authored-by: Elliott Johnson <sejohnson@torchcloudconsulting.com>

Closes #16934
This warning isn't strictly necessary and it's annoying for frameworks. The alternative is to somehow expose whether or not
experimental.asyncwas set so that frameworks can conditionally await/then the result, which is... distastefulBefore submitting the PR, please make sure you do the following
