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

• 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.
