Migration to version 3

Version 3 is essentially fully backwards compatible with previous versions, with one key exception: Zend\Config\Factory no longer requires usage of zend-servicemanager for resolving plugins.

The reason this is considered a backwards compatibility break is due to signature changes:

• Factory::setReaderPluginManager() now accepts a Psr\Container\ContainerInterface, and not a Zend\Config\ReaderPluginManager instance; ReaderPluginManager, however, still fulfills that typehint.

• Factory::getReaderPluginManager() now returns a Psr\Container\ContainerInterface — specifically, a Zend\Config\StandaloneReaderPluginManager — and not a Zend\Config\ReaderPluginManager instance, by default; ReaderPluginManager, however, still fulfills that typehint.

• Factory::setWriterPluginManager() now accepts a Psr\Container\ContainerInterface, and not a Zend\Config\WriterPluginManager instance; WriterPluginManager, however, still fulfills that typehint.

• Factory::getWriterPluginManager() now returns a Psr\Container\ContainerInterface — specifically, a Zend\Config\StandaloneWriterPluginManager — and not a Zend\Config\WriterPluginManager instance, by default; WriterPluginManager, however, still fulfills that typehint.

If you were extending the class, you will need to update your signatures accordingly.

This particular update means that you may use any PSR-11 container as a reader or writer plugin manager, and no longer require installation of zend-servicemanager to use the plugin manager facilities.
