MongoQueryCreator.nextAsArray(…) now returns a single element object array in case null is handed to the method. It previously failed with a NullPointerException.
Previously, DBObjectAccessor has always reset the in-between values when traversing nested properties. This caused previously written values to be erased if subsequent values are written. We now reuse an already existing BasicDBObject if present.
This resolves a package cycle introduced by MongoPersistentEntityIndexCreator referring to error codes now.
Updated Sonargraph architecture description along the way.
As per discussion on the ticket we now omit looking up the value for an association being used as constructor argument as the simple check whether the currently handled property is a constructor argument is sufficient to potentially skip handling the value.

We now check properties for their usage as constructor arguments, that might already have been resolved, before setting the actual value. This prevents turning already eagerly fetched DBRefs back into LazyLoadingProxies.

We now convert non quoted binary parameters to the $binary format. This allows using them along with the @Query annotation.

We now use the native id within ObjectPath for checking if a DBref has already been resolved. This is required as MongoDB Java driver 3 generation changed ObjectId.equals(…) which now performs a type check.

The presence of ObjectToObjectConverter in a DefaultConversionService causes the guard trying to register converters for ObjectIds in AbstractMongoConverter to not trigger the registration. This in turn caused ObjectId conversions to be executed via reflection instead of the straight forward method calls and thus a drop in performance for such operations.
We no unconditionally register the converters to make sure they really get applied.

We now also treat references as source of a potential index. This enforces index creation for Objects like:
@Document
class WithDbRef {
@Indexed@DBRef
ReferencedObject reference;
}
Combining @TextIndexed or @GeoSpatialIndexed with a DBRef will lead to a MappingException.

We now allow registration of ConverterFactory within CustomConversions by inspecting the generic type arguments for determining the conversion source and target types.

We now use Spring's AnnotationUtils.findAnnotation(…) for @Document lookup which enables the full power of Spring 4.2's composable annotations.

We now allow write-concern and id to be configured along with the uri or client-uri attribute of <mongo:db-factory.

Triggering data access exception translation could lead to NullPointerException in cases where PersistenceExceptionTranslator returned null because the original exception couldn't be translated and the result was directly used from a throw clause.
This is now fixed by consistently the potentiallyConvertRuntimeException(…) method, which was made static to be able to refer to it from nested static classes.
Refactored Scanner usage to actually close the Scanner instance to prevent a resource leak.
Added new build profiles mongod31 and mongo32-next to build the project against the latest MongoDB 3.1 driver as well as upcoming snapshots of the 3.2 generation.
We now directly expose the collection name via MongoMappingEvent.getCollectionName(). Therefore we added new constructors to all the events, deprecating the previous ones.
Several overloads have been added to MongoEventListener, deprecating previous API. We’ll call the deprecated from the new ones until their removal.

We now retain position parameters in paths used in queries when mapping the field name. This allows to map "list.1.name" to the name property of the first element in the list.
The change also fixes a glitch in mapping java.util.Map like structures having numeric keys.
Original pull request: #314.
We now consider the potential generic type argument of collection elements.
Prior to this change an index within List<GenericWrapper<ConcreteWithIndex>> would not have been resolved.
Original pull request: #312.
If a repository query method returned a primitive, that primitive was exposed as domain type which e.g. caused deleteBy…(…) methods to fail that returned a void.
We now shortcut the MongoEntityMetadata lookup in MongoQueryMethod to use the repository's domain type if a primitive or wrapper is returned.
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].

Replaced regex based parsing of dynamic expression based parameters with custom parsing to make sure we also support complex nested expression objects.
Previously we only supported simple named or positional expressions. Since MongoDBs JSON based query language uses deeply nested objects to express queries, we needed to improve the handling here.
Manual parsing is tedious and more verbose than regex based parsing but it gives us more control over the whole parsing process.
We also dynamically adjust the quoting so that we only output quoted parameters if necessary.
This enables to express complex filtering queries the use Spring Security constructors like:
```
@Query("{id: ?#{ hasRole('ROLE_ADMIN') ? {$exists:true} : principal.id}}")
List<User> findAllForCurrentUserById();
```
