Putting up the PR to move Preact 11 from release candidate to stable feels like something that was a long time coming for me.
I've worked on Preact X for the last 7 years, during which we had a different Preact 11 which was based on long-lived vnodes preactjs.com/blog/preact-x

Preact 11.0.0-rc.1 is here ⚛️
preact/compat code is now tree-shakeable, with representative single-export bundles shrinking by up to ~28%.
Plus: more size wins, better HTML attribute types and maintenance fixes.
This will most likely be the last rc - feedback is appreciated

Released the first release candidate of Preact 11 and I'm pretty proud that all of the packages combined actually shrunk by 100 bytes while adding A LOT of features!

Releasing Preact 11 with better hydration, moveBefore support and some reshuffling may sound like a boring release but to me it feels like completing something I've thought about for a while, I want to thank everyone for supporting Preact and enabling my journey

Preact is truly amazing.
Same React app. One is bundled as is.
Another uses preact/compat to alias React imports and swaps in Preact under the hood.
Bundle size (gzip):
React: ~140KB
Preact: ~8KB
All of this by just changing a few lines and installing a couple of packages.

At Preact we love real-browser testing, our whole test suite ran in karma for the last few years. Recently we switched over to @vitest.dev and we absolutely love it, we love it so much that we published vitest-browser-preact.
It's a library that contains tools to test Preact in vitest browser mode.

I will never understand why Preact is so slept on
Preact Signals just got a huge performance boost:
Signals rendered as text/props & effects only "pull" as fast as needed for rendering. Since computeds run as-needed, they now only re-run as often as their downstream DOM output can be painted.
H/t to @jovidecroock.com for making this happen.

back in july i started migrating preact to use vitest. ran into all sorts of problems with react, but got the green tick of joy today!
doesn't really affect preact users but will make preact easier to maintain and test once this lands

i have this unhinged fantasy that maybe in an alternative world, the “Preact” naming wasn’t taken, and server components could be called “Preact components” (pre-React, “runs before React”) which kind of helps communicate it’s a form of prerendering.

What if you could use Radix in Preact without compat?
And what if Radix itself became 60% smaller? And faster.
What if you could have all of Radix and Preact and a router... for less than half the original size of Radix? or of React?

Preact 11 has been long in the making and I'm really proud of what came out the other end.
It has quite some history as we first started working on a backing-node (fiber-like) structure for Preact but reversed.
