I do have a devlog! But for now it’s a single static page for v2, I really need to actually make it a "blog" 😭

(2. I'm not settled on the design (and I don't like it much tbh) nor the supported feature scope, feedbacks are VERY welcomed!!)

(1. The navigation took a bit of time because SC resolved the PR link after trying to resolve the initial _issue_ link (#17038 is a PR, but it wasn't a link in the API and was "linkified" as an issue cause it's the default and works for PRs too), bad demo PR choice!)

New nice little improvement in Svelte Changelog: you can now navigate between referenced issues/PRs/discussions from hashes in the descriptions! 💨

another async feature: out-of-order rendering. this means a component can begin rendering children while it's awaiting data. demo stolen from @ryansolid.bsky.social — these components should render in 3 seconds, but they only take 1: svelte.dev/playground/2...

part 5 is to enable parents and children to do work in parallel — right now, won't start loading anything until is ready to render

this is auto-enabled in SvelteKit 2.48 which we released a few minutes ago. just need to have the latest Svelte version and opt into the `experimental.async` feature (svelte.dev/docs/svelte/...)

today we landed a @svelte.dev feature i'm pretty stoked about — we call it 'forking', and it lets you run state changes offscreen and later choose whether to commit them (e.g. user hovers on a link, preload data in case they click)

- demo svelte.dev/playground/a...

The Master Plan is approaching its completion, time to bring forking in SvelteKit and get everything out of experimental! 🔥

this is what the combination of a signal graph and a compiler gets you. it's super efficient in terms of both CPU and memory (and developer effort)

there's still a couple more pieces to the async puzzle that we need to sort out, but it's coming together better than i ever thought possible

Hello, friends! After 10(!) years of #AdventOfCode, I've made some changes to preserve my sanity: there will be 12 days of puzzles each December (still starting Dec 1) and there is no longer a global leaderboard. Read more:

Thanks for everything... it's just so nice to use for This Week in Svelte (and I feel bad for just clicking on the link to open the PR on GitHub sometimes 😅) 🤟🏻

That's it for today! I also disabled logs by default, so now the cold starts should feel much faster too

Hope you enjoyed, star the repo and visit the site (yes, a new occasion to show off my gorgeous OG images I'm NOT missing on):

6/ More code snippets 💻

Last but not least, I added rendered code snippets in EVEN MORE places: they now render in snippets where the code block language is unspecified!

The diff language detection algorithm runs here too, providing some (not always perfectly accurate 😅) syntax highlighting!

Before (left) / after (right)

Not a perfect language detection, but definitely better than before!!

5/ Satisfying buttons 🤤

Following the advices of the great @emilkowal.ski, all the buttons are now subtly animated, which is very satisfying I have to admit!

4/ Videos in details 📹

Instead of being links, videos (and images) are now automatically and properly rendered!

This is what this... controversial post was doing:

3/ Commit details are BETTER 🔧

I made a bunch of changes to commit histories:
- links inside links are now separated and don't conflict
- commit details are properly formatted
- you can now see the beginning and ending dates of PRs!

2/ `theme-color` attribute 🟠

I'm a bit late to the party, but I added support for the `theme-color` meta attribute so Safari on iOS and macOS show something else than black/white on SC.

Unfortunately, Apple ditched support for this in iOS 26 in favor of dynamically computed colors :/

The top of the page in the browser, now colored orange in iOS 15-18

caniuse.com chart: only Samsung Internet and Chrome PWAs (still) support it...

1/ Links rendering inside the tracker 💅

I noticed that the links were rendered "raw" inside the tracker's list. I have a renderer for that, so I applied it.

After (notice the first 2 orange links and the linkified "hash" in the last item)

New batch of updates for Svelte Changelog!

Nothing huge, but a set of QOL improvements that will make the overall experience better.
