-The `strftime` function is widely used in the framework codebase. We plan to replace it with `IntlDateFormatter::format()`, this method comes from the `Intl` extension. CakePHP2 doesn't use it, so it would be a **breaking change**. We'd like to start rolling it out in early **May 2024**.

 ## Why I created this fork? 🤔
 
 CakePHP 2 stopped getting updates in the end of 2019 (AFAIR). Unfortunately in my case it's too expensive to migrate to newer versions of CakePHP.

+### Breaking changes
+
+- In order to get rid of `strftime()` deprecation notices, it's required to switch to `IntlDateFormatter` class. This class is available in `intl` extension, fork requires `intl` extension to be enabled in PHP configuration. If you don't have `intl` extension, installing fork will result in error. Discussed (here)[https://github.com/kamilwylegala/cakephp2-php8/pull/64] and (here)[https://github.com/kamilwylegala/cakephp2-php8/issues/65].
