v5

On 19 August 2020, it was announced that Serghei Iakovlev, one of the core contributors on the Zephir language was stepping down from the project. Antonio Braga and Kleber Faustino took over the maintenance of Zephir as well as the Zephir Parser, providing much needed support and fixes to long standing bugs. Nikolaos Dimopoulos took over the full maintenance of Phalcon. The team decided to change direction, offering v5 as a PHP extension with support for PHP 7.4 and 8.0+. For v6, Phalcon will be offered as a pure PHP implementation and will support PHP versions 8.0+. However, there will also be an extension available, for those that need extra performance. The new extension will work in parallel with v6. In v5, support for PSR interfaces has been removed. Repositories with proxy classes that implement PSR were made available for those that need these classes. Additionally, the Packagecloud repositories have been discontinued, leaving PECL the official installation source for Phalcon (other than building it from sources). During a Phalcon Hangout on 6 September 2020, the team announced that work has started on Phalcon 5. With this announcement, the projects new repositories were officially made public. Phalcon v5.0.0 was released during a live Hangout on September 23, 2022. Soon after, a bug was discovered and the team released v5.0.1 Phalcon v5.5.0 was released on Christmas Day on December 25, 2023. In this release, the team dropped support for PHP 7.4 and only supports PHP 8.0+. This was also announced in a Community Hangout two days earlier.
