I couldn't be at #guadec2026 this year but I recorded a talk about JavaScript in GNOME, static analysis, types, and some performance work that @igalia.com is supporting. Will we finally nail the Big Hammer?? Video: www.youtube.com/live/HnduDRy... Slides: ptomato.name/talks/guadec...

The Temporal proposal, co-championed by Igalia, advances to Stage 4 at TC39 — replacing JavaScript's Date API after nine years of work. Congratulations to everyone involved! Here's to better date-time handling on the web and beyond. www.igalia.com/2026/03/13/T...

Temporal is finally here, "8 yrs, 11 mos" in the making! Congrats @ptomato.name and and the champions! Humbled to be invited to the @tc39.es meeting where it moved to Stage 4. During my work on temporal-polyfill, I collaborated with the champions to improve datetime arithmetics and duration rounding

ECMAScript Euphoria! 🎉 We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4. Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

Temporal is now Stage 4 at TC39 🎂🎂🎂 Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years! I wrote a blog post explaining how we got here 📜 bloomberg.github.io/js-blog/post...
Code example showing the usage of Temporal.ZoneddateTime

```js
// London DST starts: 2026-03-29 01:00 -> 02:00
const zdt = Temporal.ZonedDateTime.from(
  "2026-03-29T00:30:00+00:00[Europe/London]",
);

console.log(zdt.toString());
// → "2026-03-29T00:30:00+00:00[Europe/London]"

const plus1h = zdt.add({ hours: 1 });

console.log(plus1h.toString());
// "2026-03-29T02:30:00+01:00[Europe/London]" (01:30 doesn't exist)

This is a good read on why monthly donations are more helpful for the GNOME Foundation than yearly or lump-sum donations. I've used GNOME for many years, and contributed to it for about half those years, and I'd love it if you'd like to join me there on the "Friends of GNOME" page
