WordPress 6.3 RC2 is ready for download and testing.

Test features in WordPress 6.3

Testing for issues is a critical part of developing any software, and it’s a meaningful way for anyone to contribute—whether you have experience or not. While testing the upgrade process is essential, trying out new features is too.
