+# Upgrade to 1.4
+
+## Minor BC Break: `Doctrine\Common\Cache\FileCache#$extension` is now `private`.
+
+If you need to override the value of `Doctrine\Common\Cache\FileCache#$extension`, then use the
+second parameter of `Doctrine\Common\Cache\FileCache#__construct()` instead of overriding
+the property in your own implementation.
+
+## Minor BC Break: file based caches paths changed
+
+`Doctrine\Common\Cache\FileCache`, `Doctrine\Common\Cache\PhpFileCache` and
+`Doctrine\Common\Cache\FilesystemCache` are using a different cache paths structure.
+
+If you rely on warmed up caches for deployments, consider that caches generated
+with `doctrine/cache` `<1.4` are not compatible with the new directory structure,
+and will be ignored.

+# Doctrine Collections
+
+[![Build Status](https://travis-ci.org/doctrine/collections.svg?branch=master)](https://travis-ci.org/doctrine/collections)
+
+Collections Abstraction library
+
+## Changelog
+
+### v1.3.0
+
+* [Explicit casting of first and max results in criteria API](https://github.com/doctrine/collections/pull/26)
+* [Keep keys when using `ArrayCollection#matching()` with sorting](https://github.com/doctrine/collections/pull/49)
+* [Made `AbstractLazyCollection#$initialized` protected for extensibility](https://github.com/doctrine/collections/pull/52)
+
+### v1.2.0
+
+* Add a new ``AbstractLazyCollection``
+
+### v1.1.0
+
+* Deprecated ``Comparison::IS``, because it's only there for SQL semantics.
+  These are fixed in the ORM instead.
+* Add ``Comparison::CONTAINS`` to perform partial string matches:
+
+        $criteria->andWhere($criteria->expr()->contains('property', 'Foo'));

+ * A Collection resembles the nature of a regular PHP array. That is,
+ * it is essentially an <b>ordered map</b> that can also be used
+ * like a list.
+ *
+ * A Collection has an internal iterator just like a PHP array. In addition,
+ * a Collection can be iterated with external iterators, which is preferable.
+ * To use an external iterator simply use the foreach language construct to
+ * iterate over the collection (which calls {@link getIterator()} internally) or
+ * explicitly retrieve an iterator though {@link getIterator()} which can then be
+ * used to iterate over the collection.
+ * You can not rely on the internal iterator of the collection being at a certain
+ * position unless you explicitly positioned it before. Prefer iteration with
+ * external iterators.
