Refactored CustomConversions to unify locked access to the cached types. Added a cache for raw-write-targets so that they’re cached, too.
DBObjectAccessor now avoids expensive code paths for both reads and writes in case of simple field names.
MappingMongoConverter now eagerly skips conversions of simple types in case the value is already assignable to the target type.
QueryMapper now checks the ConversionService and only triggers a conversion if it’s actually capable of doing so instead of catching a more expensive exception.
CachingMongoPersistentProperty now also caches usePropertyAccess() and isTransient() as they’re used quite frequently.

We now support geoNear queries in Aggregations. Exposed GeoNearOperation factory method in Aggregation. Introduced new distanceField property to NearQuery since it is required for geoNear queries in Aggregations.
Original pull request: #261.
Fixed the evaluation of the Distance for a near clause handed into a query method. Previously we evaluated against null, which will never result in true as Distance returns Metrics.NEUTRAL by default.
The JavaDoc of the geoNear(…) methods in MongoOperations now contain a hint to MongoDB limiting the number of results by default and an explicit limit on the NearQuery can be used to disable that.
Created dedicated prepareMapKey(…) method to chain calls to potentiallyConvertMapKey(…) and potentiallyEscapeMapKey(…) and make sure they always get applied in combination.
Fixed initial map creation for DBRefs to apply the fixed behavior, too.

Repository queries that used pagination and referred to a field that was customized were failing as the count query executed was not mapped correctly in MongoOperations.
This result from the fix for DATAMONGO-1080 which removed the premature field name translation from AbstractMongoQuery and thus lead to unmapped field names being used for the count query.
We now expose the previously existing, but not public count(…) method on MongoOperations that takes both an entity type as well as an explicit collection name to be able to count-query a dedicated collection but still get the query mapping applied for a certain type.

We now translate QSort's OrderSpecifiers into appropriate sort criteria.
Previously the OrderSpecifiers were not correctly translated to appropriate property path expressions.
We're now overriding support for findAll(Pageable) and findAll(Sort) to QueryDslMongoRepository to apply special QSort handling.
Original pull request: #236.
Changed SimpleMongoEntityMetadata to keep a reference to the collection entity instead of the eagerly resolved collection name. This is to make sure the name gets re-evaluated for every query execution to support dynamically changing collections defined via SpEL expressions.
Related pull request: #238.
Tweaked JavaDoc of the APIs to be less specific about implementation internals and rather point to the save(…) methods. Changed SimpleMongoRepository.save(…) methods to inspect the given entity/entities and use the optimized insert(All)-calls if all entities are considered new.
Original pull request: #253.
Introduced new insert(..) method variants on MongoRepositories that delegates to MongoTemplate.insert(..). This bypasses ID-population, save event generation and version checking and allows for fast insertion of bulk data.
Original pull request: #253.
BasicMongoPersistentEntity.getCollection() now avoids repeated SpEL-parsing and evaluating in case no SpEL expression is used. Parsing is happening at most once now. Evaluation is skipped entirely if the configured collection String is not or does not contain an expression.
We updated GroupByResults to allow working with changed data types returned for count and keys and fixed assertion on error message for duplicate keys.
Using java-driver 2.12.x when connecting to an 2.8.0.rc-0 instance is likely to cause trouble with authentication. This is the intended behavior.
2.8.0-rc0 throws error when removing elements from a collection that does not yet exist, which is different to what 2.6.x does.
The java-driver 2.13.0-rc0 works perfectly fine with a 2.6.x Server instance.
We deprecated Index.Duplicates#DROP since it has been removed in MongoDB 2.8
Original pull request: #246.
We now inspect the properties type when creating criteria for CONTAINS keyword so that, if the target property is of type String, we use an expression, and if the property is collection like we try to finds an exact match within the collection using $in.
Added support for NotContaining along the way.
Original pull request: #241.
We now have equals(…) and hashCode(…) methods on BasicQuery. Previously we solely relied on Query.hashCode()/equals(…) which didn't consider the fields of BasicQuery.
Introduced equals verifier library to automatically test equals contracts.
Added some additional test cases to BasicQueryUnitTests.
Original pull request: #252.
We now use the null-safe serailizeToJsonSafely to avoid potential RuntimeExceptions during debug query printing in MongoTemplate.
Based on original PR: #247.
Original pull request: #251.
