Security Policy

Supported Versions

As for supported PHP versions, Yasumi supports only the actively supported versions of PHP. Currently, that is PHP 7.4, and 8.0. Please refer to the supported versions page, to find more details. When a version of PHP becomes EOL, generally a new release of Yasumi will be issued that sunsets the support of that retired PHP version.

PHP 8.1 is not supported at the moment, as there is an outstanding issue with the timezone transitions in PHP 8.1. Yasumi uses the timezone transitions to determine summer-time and winter-time dates.

To investigate your request as good as possible, please include any of the following when reporting:
