3.x Migration Guide

###################

|
|
Chronos 3.x contains breaking changes that could impact your application. This
|
|
guide provides an overview of the breaking changes made in 3.x
|
|
|
|
Minimum of PHP 8.1
|
|
==================
|
|
|
|
Chronos 3.x requires at least PHP 8.1. This allows chronos to provide more
|
|
comprehensive typehinting and better performance by leveraging features found in
|
|
newer PHP versions.
|
|
|
|
MutableDateTime and MutableDate removed
|
|
=======================================
|
|
|
|
The ``MutableDateTime`` and ``MutableDate`` classes have been removed. Long term
|
|
PHP will be deprecating and removing mutable datetime classes in favour of
|
|
immutable ones. Chronos has long favoured immutable objects and removing the
|
|
mutable variants helps simplify the internals of Chronos and encourages safer
|
|
development practices.
