251
252## [7.0.0](https://github.com/ruflin/Elastica/compare/7.0.0-beta.4...7.0.0)
253### Added
254* Added `Elastica\Aggregation\WeightedAvg` aggregation [#1770](https://github.com/ruflin/Elastica/pull/1770)
255
256### Changed
257* Added missing Response information to Bulk/ResponseSet [#1776](https://github.com/ruflin/Elastica/pull/1776)
258
259
260## [7.0.0-beta.4](https://github.com/ruflin/Elastica/compare/7.0.0-beta3...7.0.0-beta.4)
261### Backward Compatibility Breaks
262* If you're **NOT** using composer to manage your libraries: the root directory of the library's source code moved from `lib/Elastica/` to `src/`.
263* The `Wildcard::setValue()` changed its signature: use it to set the value of the wildcard query only.
264* The `Wildcard` Query's constructor now requires the `name` and `value` properties.
265* The `Terms` Query's constructor now requires the `field` and `terms` properties.
266
267### Added
268* Added `AbstractTermsAggregation::setIncludeAsExactMatch()` [#1766](https://github.com/ruflin/Elastica/pull/1766)

283* Updated to PHPUnit v8.5 [#1759](https://github.com/ruflin/Elastica/pull/1759)
284* Refactored code structure: use `src/` and `tests/` folders [#1755](https://github.com/ruflin/Elastica/pull/1755)
285* Require elastica-php library >= v7.1.1, fixes an issue on Ingestion/Put() type-hinting
286* Require guzzle >= v6.3 as development library: fixes issues on PHP >= 7.2
287* Require phpunit >= v7.5, fixes deprecations in with PHP 7.3
288* Scroll is now throwing an exception when calling `current()` on an invalid iteration: always call `valid()` before
289    accessing the current item, as documented in PHP's Iterator documentation [#1749](https://github.com/ruflin/Elastica/pull/1749)
290
291### Removed

362* [Camel Case](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking-changes-7.0.html#_camel_case_and_underscore_parameters_deprecated_in_6_x_have_been_removed) and underscore parameters deprecated in 6.x have been removed
363* The parameter [fields](https://www.elastic.co/guide/en/elasticsearch/reference/master/breaking-changes-7.0.html#_the_parameter_literal_fields_literal_deprecated_in_6_x_has_been_removed_from_bulk_request) deprecated in 6.x has been removed from Bulk requestedit and Update request.

372
373
374### Bugfixes
375
376* Always set the Guzzle `base_uri` to support connecting to multiple ES hosts. [#1618](https://github.com/ruflin/Elastica/pull/1618)
377* Properly handle underscore prefixes in options and bulk request metadata ([cf upstream](https://github.com/elastic/elasticsearch/issues/26886). [#1621](https://github.com/ruflin/Elastica/pull/1621)

380
381
382### Added
383
384* support for elasticsearch-php ^7.0
385* Added `ParentAggregation` [#1616](https://github.com/ruflin/Elastica/pull/1616)

391* Move Client configuration in a dedicated class
392* Added `callable` type hinting to `$callback` in `Client` constructor. [#1659](https://github.com/ruflin/Elastica/pull/1659)
393* Added `setTrackTotalHits` method to `Elastica\Query`[#1663](https://github.com/ruflin/Elastica/issues/1663)

395
396
397### Improvements
398
399* Added `native_function_invocation` CS rule [#1606](https://github.com/ruflin/Elastica/pull/1606)
400* Elasticsearch test version changed from 6.5.2 to 6.6.1 [#1620](https://github.com/ruflin/Elastica/pull/1620)
401* Clear scroll context also when empty page was received [#1660](https://github.com/ruflin/Elastica/pull/1660)
402
403
404## [6.1.1](https://github.com/ruflin/Elastica/compare/6.1.0...6.1.1)
405
406### Added
407
408* The preferred type name is [_doc](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/removal-of-types.html), so that index APIs have the same path as they will have in 7.0
409* Added `BucketSelector` aggregation [#1554](https://github.com/ruflin/Elastica/pull/1554)
410* Added `DerivativeAggregation` [#1553](https://github.com/ruflin/Elastica/pull/1553)
411* The preferred type name is [_doc](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/removal-of-types.html), so that index APIs have the same path as they will have in 7.0

418
419### Deprecated
420* Index templates use index_patterns instead of [template](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/breaking-changes-6.0.html#_index_templates_use_literal_index_patterns_literal_instead_of_literal_template_literal)
421
422## [6.1.0](https://github.com/ruflin/Elastica/compare/6.0.2...6.1.0)
423
424### Backward Compatibility Breaks
425
426* Made result sets adhere to `\Iterator` interface definition that they implement. Specifically, you need to call `valid()` on the result set before calling `current()`. When using `foreach` this is done by PHP automatically. When `valid` returns false, the return value of `current` is undefined instead of false. [#1506](https://github.com/ruflin/Elastica/pull/1506)
427  * `\Elastica\ResultSet::next` returns `void` instead of `\Elastica\Result|false`
428  * `\Elastica\Bulk\ResponseSet::current` returns `\Elastica\Bulk\Response` instead of `\Elastica\Bulk\Response|false`
429  * `\Elastica\Multi\ResultSet::current` returns `\Elastica\ResultSet` instead of `\Elastica\ResultSet|false`
430
431### Added

442* `Aggreation\Percentiles` updated to a newer version of the Algorithm (T-Digest 3.2) and Percentiles results changed a bit Have a [look at here](https://github.com/elastic/elasticsearch/pull/28305), so updated tests in order not to fail. [#1531]([#1352](https://github.com/ruflin/Elastica/pull/1531))
443* `Aggregation\Percentiles` have been updated since [Elasticsearch 2.3](https://www.elastic.co/guide/en/elasticsearch/reference/2.3/search-aggregations-metrics-percentile-aggregation.html). In this version `compression, HDR histogram` changed their implementations. The `missing` field has never been implemented. [#1532](https://github.com/ruflin/Elastica/pull/1532)
444
445  Before
446  ```json
447    "compression" : 200,
448    "method" : "hdr",
449    "number_of_significant_value_digits" : 3
450  ```

481### Bugfixes
482- Characters "<" and ">" will be removed when a query term is passed to [`Util::escapeTerm`](https://github.com/ruflin/Elastica/pull/1415/files).

600### Bugfixes
601
602- Fix reading bool index settings like `\Elastica\Index\Settings::getBlocksWrite`. Elasticsearch returns all settings as strings and does not normalize bool values.
603  The getters now return the right bool value for whichever string representation is used like 'true', '1', 'on', 'yes'. [#1251](https://github.com/ruflin/Elastica/pull/1251)
604- Fix for QueryBuilder version check `\Elastica\QueryBuilder\Version\Version240.php` added all new query types to queries array. [#1266](https://github.com/ruflin/Elastica/pull/1266) [#1269](https://github.com/ruflin/Elastica/pull/1269)

621
622### Deprecated
623

625  Use `\Elastica\Exception\ResponseException::getResponse::getFullError` instead.
626- Deprecated both `prefix_len` & `min_word_len` fields in `Elastica\Suggest\CandidateGenerator\DirectGenerator` as these now return errors when using the phrase suggester to querying terms.
627  Use `prefix_length` & `min_word_length` instead [#1282](https://github.com/ruflin/Elastica/pull/1282)
628  Use `\Elastica\Exception\ResponseException::getResponse::getFullError` instead. [#1251](https://github.com/ruflin/Elastica/pull/1251)

633
634- `\Elastica\Script\AbstractScript` added the script language as constructor argument and sub-classes must implement `getScriptTypeArray`
635
636### Bugfixes
637
638- Removed features that do not exist in Elasticsearch 5.0 anymore:
639  - `ttl` and `timestamp` logic: setters and getters in documents and mapping
640  - `\Elastica\Query\Missing`: negate `\Elastica\Query\Exists` instead
641  - `\Elastica\Query\TopChildren`
642- `\Elastica\Query\MatchPhrase` and `\Elastica\Query\MatchPhrasePrefix` do not extend `\Elastica\Query\Match` anymore because they do not share exactly the same options
643- Removed the `routing` option in `\Elastica\Index::create` because there is no routing param when creating an index. So that option was doing nothing so far but fails in Elasticearch 5.0 because the non-existing query param is validated.
644- Fix `relation` property of `\Elastica\Query\GeoShapeProvided`
645- repoint `\Elastica\Type::exists` from the deprecated /{index}/{type} endpoint to /{index}/_mapping/{type}
646
647### Added
648
649- added `\Elastica\Script\ScriptId` to reference stored scripts by ID
650- added `\Elastica\Query\AbstractGeoShape::RELATION_WITHIN`

661  - `\Elastica\Client::optimizeAll` in favor of `\Elastica\Client::forcemergeAll`
662  - `\Elastica\Query\BoolQuery::setMinimumNumberShouldMatch` in favor of `\Elastica\Query\BoolQuery::setMinimumShouldMatch`
663  - `\Elastica\Query\GeoDistanceRange`: use distance aggregations or sorting instead
664  - `\Elastica\Query\GeohashCell`
665  - `\Elastica\Query\Indices`: search on the `_index` field instead
666  - `\Elastica\Query\Match::setFieldType`: use `\Elastica\Query\MatchPhrase` and `\Elastica\Query\MatchPhrasePrefix` instead
667- `\Elastica\Transport\Null` is deprecated because null is a reserved class name in PHP 7. Use `\Elastica\Transport\NullTransport` instead.
