preactjs/preact 5.3.0

on GitHub

🎉 Preact 5 is here! 🎈

Version 5 represents a fairly major jump forward. It should be backwards-compatible, but major version increment is to signify a few new features that will not be made available in older versions - mainly built-in SVG support, and async rendering.

Take a few seconds and upgrade, you'll be happy you did! 🌈

Tip: If you're using preact-compat, it's best to upgrade that to 2.0.0 at the same time. Since Preact 5+ now includes built-in support for SVG, preact-compat@2 drops the preact-svg dependency, saving you around 1.7kb.

Along with the lovely stable stamp, this release includes some finishing touches:

Bug Fixes

• Fix case where a ref may be nulled before a component is unmounted (#232, thanks @slmgc!)
• Ensure remounting component trees invokes mount lifecycle events for deeply nested children (thanks to @kruczy @Madumo et al for their help with this!)

New Features

• Style objects now have a lightning fast pipeline out to the DOM. (#228, thanks @trashhalo!)

  Example:
  <div style={{ foo:'bar '}} /> now diffs against the current style rather than stringifying the object
