[Bun 1.4: Now More Node.js Compatible Than Ever](https://bun.com/blog/bun-v1.4) — Several weeks after it was initially expected to launch, Bun's [big AI-powered rewrite from Zig to Rust](https://bun.com/blog/bun-in-rust) is here, complete with traditional [▶️ release video](https://www.youtube.com/watch?v=i38DgEuaJwM). A lot of effort has been put into compatibility, not just with Node, but Next.js, Playwright, Vitest, and Nuxt too. Throughput and CPU/memory usage also see huge improvements.

[Solid 2.0 RC: The Big <Reveal>](https://www.solidjs.com/blog/solid-2-0-rc-the-big-reveal) — Async now lives in the reactive graph, so async data flows through ordinary memos. `createResource`, `batch` and `startTransition` are gone. SolidStart gets retired into a `start: true` flag on the Vite plugin, and the API is now frozen.

[The Wicked Reason Removing Code Beats Better Scheduling](https://infrequently.org/2026/08/notes-on-performance-remediation-strategies/) — A lot of performance work goes into shuffling when things load, when the bigger win is usually not sending the code at all.

The consequences show up in circular dependencies and published packages.
