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.

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.

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();
```

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 use MongoExceptionTranslator to potentially convert exceptions during index creation into Springs DataAccessException hierarchy. In case we encounter an error code indicating DataIntegrityViolation we try to fetch existing index data and append it to the exceptions message.
Original pull request: #302.
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.
Original pull request: #301.
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.
Removed EvaluationExpressionContext from all AbstractMongoQuery implementations that don't actually need it and from AbstractMongoQuery itself, too. Cleaned up test cases after that.
Moved SpEL related tests into AbstractPersonRepositoryIntegrationTests to make sure they're executed for all sub-types. JavaDoc and assertion polishes.
Original pull request: #285.
Ported and adapted support for SpEL expressions @Query annotations from Spring Data JPA. StringBasedMongoQuery can now evaluate SpEL fragments in queries with the help of the given EvaluationContextProvider. Introduced EvaluationContextProvider to AbstractMongoQuery. Exposed access to actual parameter values in MongoParameterAccessor.
