• solid-router: resolve defaultNotFoundComponent at render time to avoid hydration desync (#7734) (f9b0e57ce0) by @brenelz

• @tanstack/solid-router@2.0.0-beta.23
• @tanstack/solid-start@2.0.0-beta.24
• @tanstack/solid-start-client@2.0.0-beta.23
• @tanstack/solid-start-server@2.0.0-beta.23

• Updated dependencies [f9b0e57]:
  • @tanstack/solid-router@2.0.0-beta.23

• #7734 f9b0e57 - Fix hydration desync by resolving defaultNotFoundComponent at render time instead of lazily mutating the boundary route's options.notFoundComponent. Route objects are module singletons shared across server requests, so once the server handled any 404, later SSRs of valid URLs wrapped the match in a CatchNotFound boundary the client didn't render, shifting hydration keys and leaving the subtree inert.

• #17259 ed6bea5 Thanks @astrobot-houston! - Fixes proxy support by respecting HTTP_PROXY and HTTPS_PROXY environment variables when downloading templates. On Node.js v22.21.0+ and v24.5.0+, create-astro now automatically enables the --use-env-proxy flag so that native fetch() routes requests through the configured proxy.

• #17261 79aa99c Thanks @astrobot-houston! - Fixes a false deprecation warning for markdown.gfm and markdown.smartypants when using the Container API

• #17247 f94280d Thanks @chatman-media! - Fixes route generation throwing "Missing parameter" (or silently dropping the segment) when a dynamic param's value is 0. The generator used truthy checks instead of checking for undefined, so paginate(posts, { params: { categoryId: 0 } }) would crash even though 0 is a perfectly valid param value.

• #17278 6f11739 Thanks @astrobot-houston! - Fixes missing CSS for virtual style modules (e.g., responsive image layout styles) in dev mode when JavaScript is disabled

• #17250 0b30b35 Thanks @matthewp! - Fixes the security.checkOrigin check so it is applied consistently to Astro Actions and on-demand endpoints, regardless of how the request pipeline is composed. Previously, the origin check could be skipped in the composable astro/hono pipeline depending on the order of the middleware() primitive (or when it was omitted).

• #17274 8c3579b Thanks @astrobot-houston! - Fixes missing render() type overload for live collection entries. Previously, calling render() on a LiveDataEntry produced a TypeScript error when using only live.config.ts without a content.config.ts.

• #17257 4208297 Thanks @astrobot-houston! - Fixes astro check failing to find @astrojs/check and typescript when astro is installed in a directory outside the project tree (e.g. pnpm virtual store)

• #17272 b428648 Thanks @matthewp! - Fixes island component paths so that extensionless imports (e.g. import { Counter } from '../components/Counter') resolve to the real file on disk, matching Vite's extension order and directory index resolution. This makes the include/exclude options of JSX renderer integrations (React, Preact, Solid) match components imported without a file extension, and removes the spurious React 19 "Invalid hook call" warning logged on every request in dev when include was set alongside another JSX renderer

• #17279 2aeaa44 Thanks @astrobot-houston! - Fixes a bug where <Picture inferSize> with a remote image could fail with FailedToFetchRemoteImageDimensions when the image server rate-limits requests (e.g. HTTP 429). Remote dimensions are now resolved once per render instead of once per output format.

• #17251 5240e26 Thanks @matthewp! - Hardens the handling of attribute rendering when using with custom elements.

• #17248 429bd62 Thanks @astrobot-houston! - Fixes a crash when using Astro's getViteConfig with Vitest browser mode (e.g., Storybook vitest runner). Astro now skips dev server setup inside Vitest, preventing errors.

• #17260 14524c0 Thanks @matthewp! - Fixes a regression where a <script> inside a component rendered through Astro.slots.render() was hoisted out of its original position instead of staying next to its component content
