PHP 8.1 Alpha 1 Releases on June 10
The first development version of PHP 8.1, Alpha 1, will be released on June 10, 2021. Note that these alpha releases may contain serious bugs, and are absolutely not meant to be used in production systems. Further, PHP 8.1 has not reached its feature-freeze, which means new major features may still be added to PHP 8.1 later, or even removed prior to the feature-freeze, scheduled on 20th of July, 2021.
RFCs such as pure intersection types are still in voting, and will not be included in this first alpha release.
PHP 8.1 recently elected three release managers for PHP 8.1, and PHP 8.1 Alpha 1 will be the first tagged created by them.
