Highlights include Carson Gross unveiling htmx 4.0.0 features (hx-partial, hx-action, hx-method, Alpine.js compatibility, and an upgrade helper), a talk advocating for pure HTML/CSS over React and JavaScript-heavy frameworks, insights on ORM performance pitfalls and pure SQL alternatives, the multipart/mixed HTTP Content-Type for real-time streaming, AI agent engineering for JVM developers, and running Linux on ISS hardware. The conference closed with a surprise Gameboy game bundled with htmx 4.0.0. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new features are coming in htmx 4.0.0? htmx 4.0.0 includes an upgrade helper for migrating from earlier versions, a new hx-partial element for declarative partial updates similar to an enhanced template tag, new hx-action and hx-method attributes tied into the Triptych project, and a hx-alpine-compat attribute that smooths interaction with Alpine.js. The release also emphasizes a stronger return to established web standards. _Developers planning an htmx upgrade can follow release breakdowns like this on daily.dev._ ### What is the hx-multipart extension in htmx 4.0.0? hx-multipart is an htmx 4.0.0 extension built around the multipart/mixed HTTP Content-Type header, which streams mixed data over a single connection. This header has existed in the HTML spec since 1992 but saw little developer attention until this extension surfaced it, and it offers more versatility than Server Sent Events for streaming scenarios. _Anyone weighing streaming approaches for hypermedia apps can track htmx extension updates on daily.dev._ ## Similar posts on daily.dev - [Cranking View Transtions up to 11 \(2026.05.07 @ All Day Hey\!\)](https://daily.dev/posts/cranking-view-transtions-up-to-11-2026-05-07-all-day-hey--spjrqat6n) · Bram.us · 0 upvotes · 0 comments - [A deep dive into HTMX](https://daily.dev/posts/a-deep-dive-into-htmx-uuhadafnq) · Flavio Copes · 1 upvotes · 0 comments - [HTMX 4.0: Hypermedia finds a new gear](https://daily.dev/posts/htmx-4-0-hypermedia-finds-a-new-gear-swv18ajzs) · InfoWorld · 119 upvotes · 4 comments --- Tags: [#webdev](https://daily.dev/tags/webdev), [#ai-agents](https://daily.dev/tags/ai-agents), [#sql](https://daily.dev/tags/sql), [#htmx](https://daily.dev/tags/htmx) [View this post on daily.dev](https://daily.dev/posts/big-sky-dev-con-2026-pj1hlbdp2) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Big Sky Dev Con 2026","url":"https://daily.dev/posts/big-sky-dev-con-2026-pj1hlbdp2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/big-sky-dev-con-2026-pj1hlbdp2"},"datePublished":"2026-08-01T16:59:44.383Z","dateModified":"2026-09-13T19:43:06.398Z","description":"A conference recap from Big Sky Dev Con 2026, where the author presented a talk on htmx View Transitions.
