tl;dr: Bug-Fix only release that should get rid of the last className edge cases. We encourage everyone to upgrade.
Despite our effort to account for all edge cases regarding className handling in preact/compat, we got some reports of some missed ones. This release corrects those :tada:
This release contains a fix to increase compatibility with next.js that ensures that the error overlay will show up.
Bug Fixes
Emit error event for errors handled by an error boundary (#2784, thanks @sventschui)
Fix className descriptors on Element vnodes (#2786, thanks @developit)
Fix publishing error with jsx-runtime package (#2767, thanks @johakr)
10.5.0 - JSX Reloaded
New JSX-runtime functions
This has been a long time in the making for various virtual-dom based frameworks. Historically JSX was always transpiled to createElement function calls.
// input
<div>foobar</div>
// output, we need to move "foobar" to props.children
createElement("div, {}, "foobar");
While this has served us well and is very reliable, it has proven to be hard to optimize. Most of the things we do in our createElement function could by done by babel directly, thereby making it smaller and faster. This is very desirable for us as this function is called a lot in any application. It's part of the so-called hot-path.
And that's exactly what the new signature does. It removes the need for us to pull out key from props, add back children to props and just makes the implementation simpler. As a nice benefit users won't need to manually import h/createElement anymore :tada:
