This PR was opened by the Changesets release GitHub action. When you're ready to do a release, you can merge this and the packages will be published to npm automatically. If you're not ready to do a release yet, that's fine, whenever you add more changesets to next, this PR will be updated.

⚠️⚠️⚠️⚠️⚠️⚠️

next is currently in pre mode so this branch has prereleases rather than normal releases. If you want to exit prereleases, run changeset pre exit on next.

Releases

@solidjs/babel-plugin@2.0.0-rc.19

Patch Changes

@solidjs/compiler@2.0.0-rc.19

Patch Changes

  • 9e1edbc: A lone dynamic spread on an SSR element (<label {...props()} />) now defers behind a thunk like a spread beside other attributes, so it runs after the element's hydration key. A spread that created a memo shifted the element's key on the server only, and hydration missed the element ([2.0 rc.17] A lone spread runs before the element's hydration key on the server, after it on the client #4240).
  • 4b836ab: Validate SSR templates rooted at an SVG or MathML element (such as <image> or <g> under control flow, in a fragment, or as a component root) inside their <svg>/<math> owner, as DOM templates already are, so valid SVG partials no longer fail the validate check.

@solidjs/html@2.0.0-rc.19

Patch Changes

  • 916e0eb: Decode character references in static attribute values. placeholder="Search&hellip;" rendered the literal &hellip;, an href with &amp; kept it in the URL, and components received static props like "a &amp; b" undecoded. Values are now decoded once with the HTML parser's quoted-attribute rules, as text children already were.

@solidjs/signals@2.0.0-rc.19

Patch Changes

  • 2a0da2f: fix(web): refuse an async memo that resolves to an element ([2.0.0-rc.18] renderToStream: one value seroval cannot serialize leaves every value in its hydration batch unresolved #4242)

    On the server, an async memo (or async iterable source) whose value is rendered output — JSX, a component's result, a <Loading>/<Errored> boundary — can no longer reach the hydration serializer. A boundary's output failed in seroval, so its record never resolved and the hydrating client waited on the memo forever (streamed, the boundary reverted to its fallback); a template object crossed as data, duplicating the markup, and streamed the client could not insert it (UNRECOGNIZED_INSERT_VALUE). The memo now rejects where its value lands, with the new diagnostic ASYNC_MEMO_ELEMENT (recorded on the observe channel; the dev message says what to do instead, other tiers carry the code), and its boundary contains the error like any render error: the nearest <Errored> renders its fallback and the client hydrates it; with none, the <Loading> fragment rejects and the client renders the subtree. Return data from the async memo and render the JSX from it. Ordinary data is never refused (only plain objects in the SSR template shape, boundary outputs and fragment arrays holding them count as rendered output), and content that never hydrates (<NoHydration>) is untouched.

    Also, a fragment failing while a boundary registered under an undefined key (one created inside an async memo's continuation) is pending no longer fails the whole request in renderToStream.

  • 0dd40b2: Release deferred flight bookkeeping when iterator setup or the initial pull throws, so pending verdicts clear and truth readers receive the current error.

  • 2d9c9aa: Drain pending computations after disposal, releasing retired roots while idle.

  • 4ea2f49: UNSTABLE_MEMO_OUTPUT no longer reports the memo merge() creates for a function source, such as a compiled conditional component spread (<Child {...(on() ? { tone } : {})} />). No one can pass that memo equals, so the warning had no fix (UNSTABLE_MEMO_OUTPUT fires on the memo merge() creates for a function source (<C {...cond() ? { a } : {}} />); its advice (equals) cannot be applied to that memo #4256). In observe builds the memo is now named merge. Production output is unchanged.

  • 253561e: A memo whose first read rejected stays uninitialized when it is re-asked: an isPending pass and latest() throw NotReady until a value lands instead of reading undefined ([2.0] A memo whose first read rejected reads undefined (not NotReady) in a verdict pass while it is re-asked #4244).

  • 4eb570e: Avoid retaining the first value-bound select and its form through the shared option-insertion hook.

  • e8b0b15: renderToStream: a value that fails to serialize no longer leaves the other pre-shell hydration values pending on the client ([2.0.0-rc.18] renderToStream: one value seroval cannot serialize leaves every value in its hydration batch unresolved #4242). Pending promises registered before the shell (async sources and Loading boundaries' <key>_fr completion flags) were handed to seroval as one object write. Since seroval 1.7, a value that fails to serialize ends the write it belongs to, so one failure stopped every value in that write. An async memo that resolves to an element, such as a nested <Loading>, left both boundaries unresolved and hydration never finished. The stubs are still held until the shell and handed over at the same point, in the same order, but each is now its own keyed write, so a failure only affects its own key, as on rc.17.
