This is a fork of jms/serializer at the version 1.14.1 adapted for more modern PHP development, which supports :

• PHP 7.4 <-> 8.4
• Symfony 3.4 <-> 7.2
• Doctrine 2.8 <-> 2.9

The following changes were backported from more recent versions :

• Use symfony/cache for FileSystem cache implementation instead of doctrine/cache (needed to allow doctrine/annotations 2.0)

The following changes were applied to the dev dependencies :

• PHPUnit upgraded to 9.x
• PHPStan baseline added to keep the code in good health
• Migrate Travis CI to GitHub Actions

• ReadOnly annotation was renamed to ReadOnlyProperty to avoid conflicts with PHP 8.1 readonly reserved keyword
• PHP version bumped to PHP 7.4 to prevent having to deal with PHP's Serializable cross-version compatibility...
• Doctrine dependency bumped from ~2.1 to ^2.8 (because of namespaces changes)
• Doctrine ODM PHPCR support was removed (because they removed classes and I don't know how to replace them)
• Propel support was removed as propel/propel1 is not working with PHP 8 :

PHP Fatal error:
Declaration of
  PropelOnDemandCollection::asort()
must be compatible with
  ArrayObject::asort(int $flags = SORT_REGULAR)
in vendor/propel/propel1/runtime/lib/collection/PropelOnDemandCollection.php on line 151
