Alright, Flyers! It’s been almost a year since our last major release, and we’re excited to announce a new one. We wanted to share what’s changing and why, along with how you can best plan for this update.

What’s changing and why?

Improved user experience

Better developer experience

For consistency across components, we updated the PatternFly React APIs and the default behaviors to align with design recommendations. As a result, the experience will be more seamless and less confusing.

To help you easily add consistent aria attributes, we cleaned up our aria prop names. We also removed outdated or unnecessary aria, removed problematic default heading levels that can cause accessibility issues, and added additional customization to labeling to increase flexibility in usage.

Better bundle size and performance

  • Bundle size savings of up to 103Kb, as measured in our seed app
  • Memory leak fixes
  • No more <style> tag injection
  • Support for ES2015 (ES6) browsers

How should I plan for the release?

OK, but what about the existing versions?

Please let us know in any issues posted if these need to be ported back to the older lines. Our hope is to only be porting bugs back for 2–3 milestones, but we welcome feedback about his plan.

Ready, set, release!

In the meantime, let us know if anything else comes to mind about the changes ahead. We hope you’re as excited as we are to take this next step with PatternFly.
