React Router by Remix

v8.2.0

React Router adds a Web Streams default server entry for non-Node Framework mode apps, with an opt-in flag for Node apps, and improves routing, param handling, blockers, and Vite 8+ config detection while also fixing URL encoding and route ranking issues.
What's Changed

Web Streams Default Server Entry

Non-Node runtime Framework Mode apps no longer need a custom entry.server.tsx file using React's renderToReadableStream API. Apps with @react-router/{node,express,serve} dependencies will continue to default to renderToPipeableStream, while non-Node apps default to renderToReadableStream.

Because Web Streams are stable in Node 22+, Node apps can also opt-into the Web Streams default entry with the new future.unstable_enableNodeReadableStream flag:

import type { Config } from "@react-router/dev/config"; export default { future: { unstable_enableNodeReadableStream: true, }, } satisfies Config;

This flag has no effect if you have a custom entry.server.tsx keep using their custom entry file. It only applies to the default entry used if one doesn't exist.

Node apps opting-into the Web Streams API might even see a small performance boost because React Router already uses Web Streams internally, so this avoids additional conversions between Web/Node streams. If you see perf changes one way or another upon adopting this flag, please let us know!

Minor Changes

@react-router/dev - Add a Web Streams default server entry for non-Node Framework mode apps (#15290)

Apps using @react-router/node, @react-router/express, or @react-router/serve continue to use the renderToPipeableStream default server entry

Apps without those Node server adapter dependencies use a renderToReadableStream default server entry

Non-Node apps with their own entry.server.tsx may be able to remove it in favor of the default if it is not doing anything custom

@react-router/dev - Detect nub as a supported package manager when installing framework dependencies (#15276)

create-react-router - Detect nub as a supported package manager when creating new projects (#15276)

Patch Changes

react-router - Fix href() to properly stringify and URL-encode param values, matching generatePath() (#15277)

splat params preserve path separators while encoding each segment individually

react-router - Fix dynamic param extraction for routes with optional static segments (#15200)

When a route path contains optional static segments (e.g. /school?/user/:id), the internal regex's incorrectly shifted parameter indices resulting in incorrect parameter extraction

Consecutive optional static segments (e.g. /one?/two?) were only partially handled

react-router - Preserve navigation blocker state through a revalidation (#15246)

react-router - Fix route ranking for dynamic parameters with static extension suffixes (#15273)

These were not being detected as dynamic param segments and instead got incorrectly scored higher as a static segment

This meant they could potentially tie truly static routes like /sitemap.xml and outrank them based on definition order

These are now correctly identified as dynamic parameter segments and scored correctly

react-router - Use ReactFormState types instead of unknown (#15263)

@react-router/dev - Detect user rolldownOptions config in Vite 8+ (#15278)

Unstable Changes

⚠️ Unstable features are not recommended for production use

@react-router/dev - Add the future.unstable_enableNodeReadableStream flag to opt Node Framework mode apps into using renderToReadableStream instead of renderToPipeableStream (#15290)

This flag has no effect if you have your own entry.server.tsx

Hugo

v0.164.0

Hugo adds Chroma dark and light highlighter styles, new template and crypto helpers, Pandoc citation support, and a new markup.rst.syntaxHighlight option. It also improves Page.Render layout handling and fixes a performance regression for larger sites.
Notable new features in this release are:

The Chroma highlighter styles now introduces dark/light pairs. See also the new flags on the hugo gen chromastyles command.

New template funcs encoding.HexEncode, encoding.HexDecode, and crypto.Hash.

New markup.rst.syntaxHighlight option.

We added Pandoc citation support.

We now spport sub paths in layouts passed to Page.Render.

This release also fixes a performance regression introduced in Hugo v0.128.0. This should mostly be prominent in bigger sites. See this discussion for some background.

Svelte

What’s new in Svelte: July 2026

Svelte brings a major SvelteKit and tooling update with config now supported in vite.config, preview explicit environment variables, remote function and query improvements, and broader support for new {const ...} declaration tags across the CLI and language tools.
SvelteKit config in vite.config, explicit env vars and new declaration tag support across the toolchain

This month brought a real shift in how SvelteKit projects are configured. You can now define your SvelteKit config directly inside vite.config.js and skip svelte.config.js entirely. We also got the first preview of explicit environment variables, which will eventually replace $env/* modules in SvelteKit 3.

On top of that, the language tools and the sv CLI both caught up with Svelte's new {const ...} declaration tags, so the whole toolchain is now in sync.

Let's dive in!

What's new in SvelteKit permalink

What's new in SvelteKit

You can now pass your SvelteKit config directly to the Vite plugin, so a separate svelte.config.js is no longer required, as a preview of how Kit 3 will require config to live in vite.config.js (2.62.0, Docs, #15944)

Experimental explicit environment variables let you declare and type your env vars in one place, as a preview of how $env/* will work in SvelteKit 3 (2.63.0, Docs, #15934)

Remote function commands can now receive File objects directly, so you can upload files without manually wrapping them in FormData (2.64.0, Docs, #15978)

Remote queries can now refresh other queries, making it easier to invalidate related data after a mutation (2.65.0, Docs, #16012)

Prerendered .md and .mdx files are now precompressed alongside HTML, JS and CSS for faster delivery (2.66.0, Docs, #15893)

SvelteKit now warns when boolean fields in remote form schemas are not marked optional, which is a common cause of silent submit failures (2.66.0, Docs, #15804)

The new prerender.handleInvalidUrl option lets you customize how invalid URLs found during crawling are reported (2.67.0, Docs, #16088)

RemoteFormEnhanceInstance and RemoteFormEnhanceCallback are now exported types, so you can type your custom enhance callbacks directly (2.68.0, Docs, #15816)

Submitted submit fields now keep their value in the form action payload, which makes multi-button forms easier to handle on the server (2.68.0, Docs, #15979)

For all the features and bugfixes that landed this month, check out the SvelteKit / Adapter CHANGELOGs.

What's new in the Svelte CLI and Language Tools permalink

What's new in the Svelte CLI and Language Tools

The Svelte CLI demo template now uses the new {const ...} declaration tag, so newly created projects show off the latest Svelte syntax ([email protected], #1110)

sv create now scaffolds projects against @sveltejs/kit ^2.62.0 and moves the Svelte config into the Vite plugin by default ([email protected], #1119)

A new experimental add-on lets you toggle experimental flags and opt into @next versions directly from the CLI ([email protected], #1121)

The drizzle and better-auth add-ons now support SvelteKit's new explicit environment variables ([email protected], #1122)

New defineEnv and svelteConfig helpers in @sveltejs/sv-utils make it easier to read and edit a project's Svelte config from add-ons ([email protected])

The Svelte language server, svelte-check, and svelte2tsx now understand Svelte 5's {const ...} declaration tags ([email protected]/[email protected]/[email protected], #3033)

CSS completions now work inside nested
