<h2>ECMAScript 2026 ratified with eight new features</h2>
<p>ECMA International approved ES2026 on June 30. The spec adds Math.sumPrecise for accurate floating-point summation of iterables, Iterator.concat for chaining iterators, Array.fromAsync for building arrays from async sources, Error.isError for reliable error detection, new Map and WeakMap methods for default-value retrieval, Uint8Array methods for hex and base64 conversion, and two JSON improvements: a reviver parameter that exposes raw source strings and JSON.rawJSON for controlling stringify output. Most of these are already shipping in V8 and SpiderMonkey, so practical adoption is close. <a href="https://daily.dev/posts/3ORZQHZl9" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>RFC 10008 standardizes the QUERY HTTP method</h2>
<p>The QUERY verb was ratified in June 2026, the first new standard HTTP method since PATCH landed in 2010. It fills the gap between GET and POST for read-only operations that need a request body — think complex filters in SQL or JSONPath that blow past URL length limits. Unlike POST, QUERY is safe, idempotent, and cacheable, and it supports saving queries as reusable URIs. Server and client implementations are still catching up; realistic adoption is 2027-2028. <a href="https://daily.dev/feed-by-ids?id=DupkyDtLO&amp;id=AQ9tUPYyH" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Cloudflare Workers Cache adds a tiered cache in front of Workers</h2>
<p>Cloudflare launched Workers Cache, enabled with a single Wrangler config line. Cache hits skip Worker execution entirely, which directly cuts CPU billing. It supports standard Cache-Control and Cache-Tag headers, stale-while-revalidate, Vary headers, and per-entrypoint cache control within a single Worker. Multi-tenant setups get safe cache key isolation via ctx.props. Astro already has built-in integration; available now at no additional cost beyond standard request rates. <a href="https://daily.dev/posts/iuM8TvTYb" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Astro 7 ships with a Rust compiler and 15-61% faster builds</h2>
<p>Astro 7 rewrites the compiler in Rust and moves the Markdown/MDX pipeline to Rust as well, cutting build times by 15-61% depending on project size. The release also stabilizes queue-based rendering, route caching, and a new fetch entry point for full request lifecycle control. Cloudflare now backs Astro and also acquired VoidZero — the company behind Vite and Evan You — which signals tighter coupling between these tools and Cloudflare’s infrastructure going forward. <a href="https://daily.dev/posts/NSfR3BEeo" target="_blank" rel="noopener nofollow">Read more</a></p>
