As this release breaks backward compatibility, a detailed explanation about the breaking changes can be found here

Backward Compatibility Breaks

• Objects do not casts to arrays in setters and saved in params as objects. There is many side effects if
  you work with params on "low-level" or change your objects after you call setter with object
  as argument. #916

Added

• Add Script File feature #902 #914

Improvements

• Support the http.compression in the Http transport adapter #515
• Introduction of Lazy toArray #916
• Update Elasticsearch dependency to 1.7.2 #929

Release 2.2.1

Added

• Support for index template added #905

Improvements

• Update Elasticsearch dependency to 1.7.1 and update plugin dependencies #909
• Update php-cs-fixer to 1.10 #898
• Elastica\QueryBuilder now uses Elastica\QueryBuilder\Version\Latest as default version to avoid empty version classes. #897
• Update elasticseach-image to work with ES 1.7.1 #907
• Local dev environment was refactored to fully work in docker environment. Running tests is now only one command: make tests #901

Deprecated

• Elastica\QueryBuilder\Version\Version150 deprecated in favor of Elastica\QueryBuilder\Version\Latest #897

Release 2.2.0

Backward Compatibility Breaks

• Usage of constant DEBUG and method Elastica\Util::debugEnabled is removed. #868
• Elastica\Response::getTransferInfo will not return "request_header" by default. #868
• The Image Plugin is currently not compatible with Elasticearch 1.6.0

Bugfixes

• Fixed segmentation fault in PHP7 #868
• Removed deprecation for Elastica\Type::deleteByQuery #875

Improvements

• CallbackStrategy now will accept any callable as callback, not only instance of Closure. #871
• StrategyFactory now will try to find predefined strategy before looking to global namespace. #877
• Update elasticsearch dependency to elasticsearch 1.6.0 https://www.elastic.co/downloads/past-releases/elasticsearch-1-6-0
• All elasticsearch plugin dependencies were updated to the newest version.
• Methods of classes in QueryBuilder\DSL namespace now have exact same signatures as corresponding constructors. #878
• Constructor of Aggregation\Filter now accepts filter as second parameter #878
• Constructor of Filter\AbstractMulti (BoolAnd, BooldOr) now accepts array of filters as parameter #878
• Constructor of Query\Match now accepts arguments #878
• Coverage Reporting improved with Codecov #888
• Added 'query_cache' option for search #886

Release 2.1.0

Backward Compatibility Breaks

• Elastica\ScanAndScroll::$_lastScrollId removed: key() now always returns the next scroll id #842

Deprecated

• Facets are deprecated. You are encouraged to migrate to aggregations instead. #855
• Elastica\Query\Builder is deprecated. Use new Elastica\QueryBuilder instead. #855
• For PHP 7 compatibility Elastica\Query\Bool was renamed to *\BoolQuery, Elastica\Filter\Bool was renamed to BoolFilter, Elastica\Transport\Null was renamed to NullTransport as Null and Bool are reserved phrases in PHP 7. Proxy objects for all three exist to keep backward compatibility. It is recommended to start using the new objects as the proxy classes will be deprecated as soon as PHP 7 is stable. #837

Added

• Multiple rescore query #820
• Support for a custom connection timeout through a connectTimeout parameter. #841
• SignificantTerms Aggregation #847
• Support for 'precision_threshold' and 'rehash' options for the Cardinality Aggregation [#851]
• Support for retrieving id node #852
• Scroll Iterator #842
• Gitter Elastica Chat Room add for Elastica discussions: https://gitter.im/ruflin/Elastica
• Introduce PHP7 compatibility and tests. #837
• Tool\CrossIndex for reindexing and copying data and mapping between indices #853
• CONTIRUBTING.md file added for contributor guidelines. #854

Improvements

• Introduction of Changelog standard based on http://keepachangelog.com/. changes.txt moved to CHANGELOG.md #844
• Make host for all tests dynamic to prepare it for a more dynamic test environment #846
• Node information is retrieved based on id instead of name as multiple nodes can have the same name. #852
• Guzzle Http dependency updated to 5.3.*
• Remove NO_DEV builds from travis build matrix to speed up building. All builds include no dev packages.
• Introduction of benchmark test group to make it easy to run benchmark tests.
• Make the docker images directly available on the docker registry. This speeds up fetching of the images and automates the build of the images.

Release 2.0.0

Release Notes

With this release Elastica moves to its own independent semantic versioning. It starts with the jump from Elastica v1.4.3.0 to 2.0.0. The compatible elasticsearch version will be linked with every release. This changes makes it possible to better indicate major branches to previous Elastica versions without being dependent on elasticsearch release version numbering. The v in front of the version was dropped.

Release 2.0.0 has only minor backward compatibility breaks (see below), but lots of improvements and additions. All BC changes are related to changes in elasticsearch 1.5.*. Migration from v1.4.3.0 to 2.0.0 should not be an issue in most cases even though it is a big step concerning version number.

The goal is also to improve on the release notes to make it easier to see what changes and what are the backward compatible changes. More details can be found here
