+# 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.

+# Contribute to Doctrine
+
+Thank you for contributing to Doctrine!
+
+Before we can merge your Pull-Request here are some guidelines that you need to follow.
+These guidelines exist not to annoy you, but to keep the code base clean,
+unified and future proof.
+
+## We only accept PRs  to "master"
+
+Our branching strategy is "everything to master first", even
+bugfixes and we then merge them into the stable branches. You should only 
+open pull requests against the master branch. Otherwise we cannot accept the PR.
+
+There is one exception to the rule, when we merged a bug into some stable branches
+we do occasionally accept pull requests that merge the same bug fix into earlier
+branches.
+
+## Coding Standard
+
+We use the [Doctrine Coding Standard](https://github.com/doctrine/coding-standard).
+
+## Unit-Tests
+
+Please try to add a test for your pull-request.
+
+* If you want to contribute new functionality add unit- or functional tests
+  depending on the scope of the feature.
+
+You can run the unit-tests by calling ``vendor/bin/phpunit`` from the root of the project.
+It will run all the project tests.
+
+In order to do that, you will need a fresh copy of doctrine/collections, and you
+will have to run a composer installation in the project:
+
+```sh
+git clone git@github.com:doctrine/collections.git
+cd collections
+curl -sS https://getcomposer.org/installer | php --
+./composer.phar install
+```
+
+## Travis
+
+We automatically run your pull request through [Travis CI](https://www.travis-ci.org)
+against supported PHP versions. If you break the tests, we cannot merge your code,
+so please make sure that your code is working before opening up a Pull-Request.
+
+## Getting merged
+
+Please allow us time to review your pull requests. We will give our best to review
+everything as fast as possible, but cannot always live up to our own expectations.
+
+Thank you very much again for your contribution!

+## Changelog
+
+### v1.6.1
+
+This release, combined with the release of [`doctrine/collections` `v1.6.1`](https://github.com/doctrine/collections/releases/tag/v1.6.1),
+fixes an issue where parsing annotations was not possible
+for classes within `doctrine/collections`.
+
+Specifically, `v1.6.0` introduced Psalm-specific annotations
+such as (for example) `@template` and `@template-implements`,
+which were both incorrectly recognized as `@template`.
+
+`@template` has therefore been removed, and instead we use
+the prefixed `@psalm-template`, which is no longer parsed
+by `doctrine/collections` `v1.6.1`
+
+Total issues resolved: **1**
+
+- [186: Use `@psalm-template` annotation to avoid clashes](https://github.com/doctrine/collections/pull/186) thanks to @muglug
+
+### v1.6.0
+
+This release bumps the minimum required PHP version to 7.1.3.
+
+Following improvements were introduced:
+
+ * `ArrayCollection#filter()` now allows filtering by key, value or both.
+ * When using the `ClosureExpressionVisitor` over objects with a defined
+   accessor and property, the accessor is prioritised.
+ * Updated testing tools and coding standards, autoloading, which also
+   led to marginal performance improvements
+ * Introduced generic type docblock declarations from [psalm](https://github.com/vimeo/psalm),
+   which should allow users to declare `/** @var Collection<KeyType, ValueType> */`
+   in their code, and leverage the type propagation deriving from that.
+
+Total issues resolved: **16**

+Derived Collections
+===================

+You can create custom collection classes by extending the

+Expressions
+===========
+
+The ``Doctrine\Common\Collections\Expr\Comparison`` class
+can be used to create expressions to be used with the
+``Doctrine\Common\Collections\Criteria`` class. It has the
+following operator constants:
+
+- ``Comparison::EQ``
+- ``Comparison::NEQ``
+- ``Comparison::LT``
+- ``Comparison::LTE``
+- ``Comparison::GT``
+- ``Comparison::GTE``
+- ``Comparison::IS``
+- ``Comparison::IN``
+- ``Comparison::NIN``
+- ``Comparison::CONTAINS``
+- ``Comparison::MEMBER_OF``
+- ``Comparison::STARTS_WITH``
+- ``Comparison::ENDS_WITH``
+
+The ``Doctrine\Common\Collections\Criteria`` class has the following
+API to be used with expressions:
+
+where
+-----
+
+Sets the where expression to evaluate when this Criteria is searched for.
+
+.. code-block:: php

+Introduction
+============
+
+Doctrine Collections is a library that contains classes for working with
+arrays of data. Here is an example using the simple
+``Doctrine\Common\Collections\ArrayCollection`` class:
+
+.. code-block:: php
+    <?php
+
+    use Doctrine\Common\Collections\ArrayCollection;
+
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $filteredCollection = $collection->filter(function($count) {
+        return $count > 1;
+    }); // [2, 3]
+
+Collection Methods
+==================
+
+Doctrine Collections provides an interface named ``Doctrine\Common\Collections\Collection``
+that resembles the nature of a regular PHP array. That is,
+it is essentially an **ordered map** 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 ``getIterator()`` internally, or
+explicitly retrieve an iterator though ``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.
+
+The methods available on the interface are:
+
+add
+---
+
+Adds an element at the end of the collection.
+
+.. code-block:: php
+    $collection->add('test');
+
+clear
+-----
+
+Clears the collection, removing all elements.
+
+.. code-block:: php
+    $collection->clear();
+
+contains
+--------
+
+Checks whether an element is contained in the collection. This is an O(n) operation, where n is the size of the collection.
+
+.. code-block:: php
+    $collection = new Collection(['test']);
+
+    $contains = $collection->contains('test'); // true
+
+containsKey
+-----------
+
+Checks whether the collection contains an element with the specified key/index.
+
+.. code-block:: php
+    $collection = new Collection(['test' => true]);
+
+    $contains = $collection->containsKey('test'); // true
+
+current
+-------
+
+Gets the element of the collection at the current iterator position.
+
+.. code-block:: php
+    $collection = new Collection(['first', 'second', 'third']);
+
+    $current = $collection->current(); // first
+
+get
+---
+
+Gets the element at the specified key/index.
+
+.. code-block:: php
+    $collection = new Collection([
+        'key' => 'value',
+    ]);
+
+    $value = $collection->get('key'); // value
+
+getKeys
+-------
+
+Gets all keys/indices of the collection.
+
+.. code-block:: php
+    $collection = new Collection(['a', 'b', 'c']);
+
+    $keys = $collection->getKeys(); // [0, 1, 2]
+
+getValues
+---------
+
+Gets all values of the collection.
+
+.. code-block:: php
+    $collection = new Collection([
+        'key1' => 'value1',
+        'key2' => 'value2',
+        'key3' => 'value3',
+    ]);
+
+    $values = $collection->getValues(); // ['value1', 'value2', 'value3']
+
+isEmpty
+-------
+
+Checks whether the collection is empty (contains no elements).
+
+.. code-block:: php
+    $collection = new Collection(['a', 'b', 'c']);
+
+    $isEmpty = $collection->isEmpty(); // false
+
+first
+-----
+
+Sets the internal iterator to the first element in the collection and returns this element.
+
+.. code-block:: php
+    $collection = new Collection(['first', 'second', 'third']);
+
+    $first = $collection->first(); // first
+
+exists
+------
+
+Tests for the existence of an element that satisfies the given predicate.
+
+.. code-block:: php
+    $collection = new Collection(['first', 'second', 'third']);
+
+    $exists = $collection->exists(function($key, $value) {
+        return $value === 'first';
+    }); // true
+
+filter
+------
+
+Returns all the elements of this collection that satisfy the predicate. The order of the elements is preserved.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $filteredCollection = $collection->filter(function($count) {
+        return $count > 1;
+    }); // [2, 3]
+
+forAll
+------
+
+Tests whether the given predicate holds for all elements of this collection.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $forAll = $collection->forAll(function($key, $value) {
+        return $value > 1;
+    }); // false
+
+indexOf
+-------
+
+Gets the index/key of a given element. The comparison of two elements is strict, that means not only the value but also the type must match. For objects this means reference equality.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $indexOf = $collection->indexOf(3); // 2
+
+key
+---
+
+Gets the key/index of the element at the current iterator position.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $collection->next();
+
+    $key = $collection->key(); // 1
+
+last
+----
+
+Sets the internal iterator to the last element in the collection and returns this element.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $last = $collection->last(); // 3
+
+map
+---
+
+Applies the given function to each element in the collection and returns a new collection with the elements returned by the function.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $mappedCollection = $collection->map(function($value) {
+        return $value + 1;
+    }); // [2, 3, 4]
+
+next
+----
+
+Moves the internal iterator position to the next element and returns this element.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $next = $collection->next(); // 2
+
+partition
+---------
+
+Partitions this collection in two collections according to a predicate. Keys are preserved in the resulting collections.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $mappedCollection = $collection->partition(function($key, $value) {
+        return $value > 1
+    }); // [[2, 3], [1]]
+
+remove
+------
+
+Removes the element at the specified index from the collection.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $collection->remove(0); // [2, 3]
+
+removeElement
+-------------
+
+Removes the specified element from the collection, if it is found.
+
+.. code-block:: php
+    $collection = new ArrayCollection([1, 2, 3]);
+
+    $collection->removeElement(3); // [1, 2]
+
+set
+---
+
+Sets an element in the collection at the specified key/index.
+
+.. code-block:: php
+    $collection = new ArrayCollection();
+
+    $collection->set('name', 'jwage');
+
+slice
+-----
+
+Extracts a slice of $length elements starting at position $offset from the Collection. If $length is null it returns all elements from $offset to the end of the Collection. Keys have to be preserved by this method. Calling this method will only return the selected slice and NOT change the elements contained in the collection slice is called on.
+
+.. code-block:: php
+    $collection = new ArrayCollection([0, 1, 2, 3, 4, 5]);
+
+    $slice = $collection->slice(1, 2); // [1, 2]
+
+toArray
+-------
+
+Gets a native PHP array representation of the collection.
+
+.. code-block:: php
+    $collection = new ArrayCollection([0, 1, 2, 3, 4, 5]);
+
+    $array = $collection->toArray(); // [0, 1, 2, 3, 4, 5]
+
+Selectable Methods
+==================
+
+Some Doctrine Collections, like ``Doctrine\Common\Collections\ArrayCollection``,
+implement an interface named ``Doctrine\Common\Collections\Selectable``
+that offers the usage of a powerful expressions API, where conditions
+can be applied to a collection to get a result with matching elements
+only.
+
+matching
+--------
+
+Selects all elements from a selectable that match the expression and
+returns a new collection containing these elements.
+
+.. code-block:: php
+    use Doctrine\Common\Collections\Criteria;
+    use Doctrine\Common\Collections\Expr\Comparison;
+
+    $collection = new ArrayCollection([
+        [
+            'name' => 'jwage',
+        ],
+        [
+            'name' => 'romanb',
+        ],
+    ]);
+
+    $expr = new Comparison('name', '=', 'jwage');
+
+    $criteria = new Criteria();
+
+    $criteria->where($expr);
+
+    $matched = $collection->matching($criteria); // ['jwage']

+Lazy Collections
+================
+
+To create a lazy collection you can extend the
+``Doctrine\Common\Collections\AbstractLazyCollection`` class
+and define the ``doInitialize`` method. Here is an example where
+we lazily query the database for a collection of user records:
+
+.. code-block:: php
+    use Doctrine\DBAL\Connection;
+
+    class UsersLazyCollection extends AbstractLazyCollection
+    {
