It’s really great to hear from PHP Core developer Nikita Popov, interviewing Symfony principal engineer Nikolas Grekas. In this interview they discussed problems the Symfony team encountered while making the framework compatible with the upcoming PHP 8 release.
In addition to new PHP8 features, which should be available in about two months, there are tons of backward compatibility breaks that you can find in this upgrading document. Thanks to Jetbrains for making this interview available, after a month of its recording, the format is great but freezing an interview for such long time will make it loose its purpose.
