 # Change Log
 All notable changes to this project will be documented in this file based on the [Keep a Changelog](http://keepachangelog.com/) Standard. This project adheres to [Semantic Versioning](http://semver.org/).
 
-## [Unreleased](https://github.com/ruflin/Elastica/compare/3.1.1...HEAD)
+## [Unreleased](https://github.com/ruflin/Elastica/compare/3.2.1...HEAD)
+
+### Backward Compatibility Fixes
+
+### Bugfixes
+- Set HTTP headers on each request preventing server error if persistent connection is enabled and compression enabled and later disabled for the same connection.
+
+### Added
+- Elastica\QueryBuilder\DSL\Query::geo_distance
+
+### Improvements
+- Set PHP 7.0 as default development version
+- Get the root reason from Elasticsearch's error JSON, when available [#1111](https://github.com/ruflin/Elastica/pull/1111)
+
+## [3.2.1](https://github.com/ruflin/Elastica/compare/3.2.0...3.2.1)
+
+### Backward Compatibility Fixes
+- Reintroduced properties in ResultSet removed in 3.2.0 as deprecated properties to be removed in 4.0
+
+### Bugfixes
+- Fix fatal error on `Query::addScriptField()` if scripts were already set via `setScriptFields()` [#1086](https://github.com/ruflin/Elastica/pull/1086)
+- Fix namespace collision of `Type` in `Query\Ids` [#1104](https://github.com/ruflin/Elastica/pull/1104)
+
+### Added
+- Added the concept of ResultSet Transformers. The Transformer adds more information to a Result, for example the original object or data that created the Result. [#1066](https://github.com/ruflin/Elastica/pull/1066)
+- Tidied property initialisation in classes where it was duplicated
+
+## [3.2.0](https://github.com/ruflin/Elastica/compare/3.1.1...3.2.0)
 
 ### Backward Compatibility Breaks
+- Method \Elastica\ResultSet::create and property \Elastica\ResultSet::$class were removed. To change the ResultSet class, implement your own ResultSet Builder. [#1065](https://github.com/ruflin/Elastica/pull/1065)
+- Properties on \Elastica\ResultSet _totalHits, _maxScore, _took and _timedOut that were originally set on object construction are now accessed by the getters on the ResultSet. [#1065](https://github.com/ruflin/Elastica/pull/1065)
 
 ### Bugfixes
+- Fix php notice on `\Elastica\Index::getAliases()` if index has no aliases [#1078](https://github.com/ruflin/Elastica/issues/1078)
 
 ### Added
+- Update elasticsearch build dependency to elasticsearch 2.3.2 [#1084](https://github.com/ruflin/Elastica/pull/1084)
 
 ### Improvements
+- `Elastica\Type->deleteByQuery($query, $options)` $query param can be a query `array` again https://github.com/ruflin/Elastica/issues/1072 [#1073](https://github.com/ruflin/Elastica/pull/1073)
+- `Elastica\Client->connect()` allows to establish a connection to ES server when the config was set using method `Elastica\Client->setConfigValue()` https://github.com/ruflin/Elastica/issues/1076 [#1077](https://github.com/ruflin/Elastica/pull/1077)
+- Elastica\Client constructor now accepts a LoggerInterface and will log both successful and failed requests. [#1069](https://github.com/ruflin/Elastica/pull/1069)
 
 ### Deprecated
+- Configuring the logger in \Elastica\Client $config constructor is deprecated and will be removed. Use the $logger argument instead. [#1069](https://github.com/ruflin/Elastica/pull/1069)
+- Extracted creation of ResultSet objects to a new dedicated ResultSet\Builder implementation. [#1065](https://github.com/ruflin/Elastica/pull/1065)
+
+### Deprecated
+- All properties in the \Elastica\ResultSet class will be moved to private in 4.0. To manipulate the creation of a ResultSet, implement the \Elastica\ResultSet\BuilderInterface and pass your new Builder to the \Elastica\Search instances. [#1065](https://github.com/ruflin/Elastica/pull/1065)
 
 
 ## [3.1.1](https://github.com/ruflin/Elastica/compare/3.1.0...3.1.1)
 
 ### Added
-- Add an "AwsAuthV4" transport that automatically signs requests using credentials from the environment or from the client config. This allows using Elastica with Amazon ElasticSearch Service domains that are restricted to IAM roles or policies. https://github.com/ruflin/Elastica/pull/1056
