The PHP project has tagged PHP 8.6.0alpha2, a pre-release build of the upcoming 8.6 branch. It is meant for testing, not for production: the 47 changelog entries across 21 components — among them Core, Calendar, Curl, Date, DBA, DOM … — preview what 8.6 will ship.

Now is the time to run your applications and extensions against this build and report regressions upstream — every issue caught before GA saves the whole ecosystem an upgrade headache. The changelog so far is below; QA builds are available on qa.php.net.
