We now push the aliased field name down the aggregation pipeline for projections including operations. This allows to reference them in a later stage. Prior to this change the field reference was potentially resolved to the target field of the operation which did not result in an error but lead to false results.

We now reject configuration using MongoClient along with UserCredentials in SimpleMongoDbFactory. This move favors the native authentication mechanism provided via MongoCredential.
<mongo:mongo-client id="mongo-client-with-credentials" credentials="jon:warg@snow?uri.authMechanism=PLAIN" />
Original pull request: #309.
We now allow grouping credentials by enclosing them in single quotes like this:
credentials='CN=myName,OU=myOrgUnit,O=myOrg,L=myLocality,ST=myState,C=myCountry?uri.authMechanism=MONGODB-X509'
We also changed the required argument checks to be more authentication mechanism specific which means the pattern is now username[:password@database][?options].

UpdateMapper.getMappedObjectForField(…) invokes the very same method of the super class but handed in an already mapped value so that value conversion was invoked twice.
This was especially problematic in cases a dedicated converter had been registered for an object that is already a Mongo-storable one (e.g. an enum-to-string converter and back) without indicating which of the tow converter is the reading or the writing one. This basically caused the source value converted back and forth during the update mapping creating the impression the value wasn't converted at all.
This is now fixed by removing the superfluous mapping.
Removed the creation of a BasicMongoPersistentEntity in favor of always handing ClassTypeInformation.OBJECT into the converter in case not entity can be found.
This makes sure type information is written for updates on properties of type Object (which essentially leads to no PersistentEntity being available).

We now use property type information when mapping fields affected by an update in case we do not have proper entity information within the context. This allows more precise type resolution required for determining the need to write type hints for a given property.

We now quote the original criteria before actually wrapping it inside of an regular expression for case insensitive search. This happens not only to case insensitive is, startsWith, endsWith criteria but also to those using like. In that case we quote the part between leading and trailing wildcard if required.

We now eagerly check DBRef properties for invalid definitions such as final class or array. In that case we throw a MappingException when verify is called.
Previously we tried to apply the ignore case settings found in the PartTree to the root PropertyPath we handle in MongoQueryCreator.create(). This is now changed to work on the leaf property of the PropertyPath.
We now inspect the actual field type during update mapping and provide a type hint accordingly. Simple, non interface and non abstract types will no longer be decorated with the _class attribute. We now honor positional parameters when trying to map paths to properties. This allows more decent type mapping since we have now access to the meta model which allows us to check if presence of type hint (aka _class) is required.
We now add a special type hint indicating nested types to the converter. This allows more fine grained removal of _class property without the need to break the contract of MongoWriter.convertToMongoType(…).
Original pull request: #292.
The problem stems from the inconsistent handling of type hints such as MongoTemplate.save(…) does not add a type hint, but findAndModify(…) does. The same values are then treated differently by MongoDB, depending on whether they have a type hint or not. To verify this behavior, you can manually add the (superfluous) type hint to the saved object - findAndModify will then work as expected.
Additional tests demonstrate that findAndModify(…) removes type hints from complex documents in collections that are either nested in another collection or in a document, or doesn't add them in the first place.

We now skip authentication via an explicit AuthDB when requesting a DB via a MongoClient instance.

We now use TypeInformation in IndexResolver to lookup the root PersistentEntity for resolving @Indexed properties to ensure that we retrieve the same PersistentEntity that was stored. Previously we used the Class to lookup up the PersistentEntity which yielded a partially processed result.
Original pull request: #293.
We now check against the used driver version before requesting db instance from factory. Potential improvements on fetch strategy for MongoDB Java Driver 3 will be handled in DATAMONGO-1194.

Removed obsolete generics in MongoPersistentEntityIndexCreator to make sure MappingContextEvents are delivered to the listener on Spring 4.2 which applies more strict generics handling to ApplicationEvents.
Tweaked PersonBeforeSaveListener in test code to actually reflect how an ApplicationEventListener for MongoDB would be implemented.
Removed deprecated (and now removed) usage of ConversionServiceFactory in AbstractMongoConverter. Added MongoMappingEventPublisher.publishEvent(Object) as NoOp.
If a collection containing null values is handed to MongoTempalte.insertAll(…), a NullPointerException was caused by the unguarded attempt to lookup the class of the element. We now explicitly handle this case and skip the element.
Some code cleanups in MongoTemplate.doInsertAll(…).
Add repository query return types to reference doc.
Fall back to locally available Spring Data Commons reference docs as the remote variant doesn't seem to work currently
Introduced AggregationExpression interface to be able to represent arbitrary MongoDB expressions that can be used in projection and group operations. Supported function expressions are provided via the AggregationFunctionExpressions enum.
Original pull request: #272.
Added the necessary configuration infrastructure to automatically register the GeoJsonModule as Spring bean when @EnableSpringDataWebSupport is used. This is implemented by exposing a configuration class annotated with @SpringDataWebConfigurationMixin.
Added Spring WebMVC as test dependency to be able to write an integration test. Polished GeoJsonModule to hide the actual serializers.
