-## 2.7.0 - TBD

 ### Added
 
-- Nothing.
+- [#36](https://github.com/zendframework/zend-config/pull/36) adds support for
+  [PSR-11](http://www.php-fig.org/psr/psr-11/).
+
+- [#36](https://github.com/zendframework/zend-config/pull/36) adds the class
+  `Zend\Config\StandaloneReaderPluginManager` for managing config reader plugins.
+  This implementation implements the PSR-11 `ContainerInterface`, and uses a
+  hard-coded list of reader plugins.
+
+- [#36](https://github.com/zendframework/zend-config/pull/36) adds the class
+  `Zend\Config\StandaloneWriterPluginManager` for managing config writer plugins.
+  This implementation implements the PSR-11 `ContainerInterface`, and uses a
+  hard-coded list of writer plugins.
+
+### Changes
+
+- [#36](https://github.com/zendframework/zend-config/pull/36) updates the
+  `Zend\Config\Factory::getReaderPluginManager()` method to lazy-load a
+  `StandaloneReaderPluginManager` by default, instead of a
+  `ReaderPluginManager`, allowing usage out-of-the-box without requiring
+  zend-servicemanager.
+
+- [#36](https://github.com/zendframework/zend-config/pull/36) updates the
+  `Zend\Config\Factory::setReaderPluginManager()` method to typehint against
+  `Psr\Container\ContainerInterface` instead of `ReaderPluginManager`. If you
+  were extending and overriding that method, you will need to update your
+  signature.
+
+- [#36](https://github.com/zendframework/zend-config/pull/36) updates the

+  `StandaloneWriterPluginManager` by default, instead of a

 ### Removed
 
-- Nothing.
+- [#36](https://github.com/zendframework/zend-config/pull/36) removes usage of
+  zend-json as a JSON de/serializer in the JSON writer and reader; the
+  component now requires ext/json is installed to use these features.

+# 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` &mdash; specifically, a
+  `Zend\Config\StandaloneReaderPluginManager` &mdash;  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` &mdash; specifically, a
+  `Zend\Config\StandaloneWriterPluginManager` &mdash;  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.
