The check for keywords in QueryMapper now selectively decides between checks for a nested keyword (DBObject) object and the check for a simple key. This allows the usage of criteria values starting with $ (e.g. { 'myvalue' : '$334' }) without the value being considered a keyword and thus erroneously triggering a potential conversion of the value.
Moved more logic for a keyword into the Keyword value object.
In our Querydsl MongodbSerializer implementation we now only inspect the MongoPersistentProperty for a field name if the given path is really a property path. Previously we tried to always resolve a persistent property even if the given path was an array index path, a map key or the like.
Added an additional section to chapter 7.3 that describes the parameter value binding when the @PersistenceConstructor annotation including a small usage example. Added a concrete example for the @Value annotation that uses SpEL.

GroupOperation gets the _id field now rendered as null if no group fields were added to the operation. Previously it was rendered as empty document (i.e. { }). While this was technically correct as well, we're now closer to what the MongoDB reference documentation describes.
Original pull request: #73.
Adjusted FieldProjection to generate an appropriate representation of included / excluded fields (namely :1 for included and :0 for excluded).
Polished guards to handle only _id is allowed to be excluded (DATAMONGO-758).

Aggregation pipelines now correctly handle nested field references in aggregation operations. We introduced FieldsExposingAggregationOperation to mark AggregationOperations that change the set of exposed fields available for processing by later AggregationOperations. Extracted context state out of AggregationOperation to ExposedFieldsAggregationContext for better separation of concerns. Modified toDbObject(…) in Aggregation to only replace the aggregation context when the current AggregationOperation is a FieldExposingAggregationOperation.

Added support for skipping elements for NearQuery in MongoTemplate. As mongodb currently (2.4.4) doesn't support he skipping of elements in geoNear-Queries we skip the unnecessary elements ourselves. We use the limit & skip information from the given query or an explicitly passed Pageable.
Original pull request: #64.
Added a reading converter to dump DBObject instances into a String directly to enable executing queries against MongoDB into a String version of the query result without marshaling the DBObject into a Map first.
Added appropriate overloaded methods to MongoOperations and MongoTemplate. Applied pull request from Chuong Ngo <chuong.h.ngo.ctr@mail.mil>.
Original pull request: #57.
Added new attribute type-mapper-ref to the mapping-converter element in spring-mongo-1.3.xsd in order to support the configuration of custom-type-mappers. Removed the unsupported attributes "mongo-ref" and "mongo-template-ref" from the mapping-converter element in spring-mongo-1.3.xsd because they are not considered anymore.
Updated MappingMongoConverterParser to be aware of the new attribute. Added examples for configuring a custom MongoTypeMapper the usage of @TypeAlias to the reference documentation.
Original pull request: #61.
Added a guard to Criteria#(and|or|nor)Operator to prevent wrapping $and, $or or $nor expressions in a $not expression as mongodb currently doesn't support this. Added test case to CriteriaTests to verify that not() works as specified.
Original pull request: #60.
Fixed using the actual field reference instead of the field name on resolving. Added equals(…) and hashCode() methods to value objects. Added unit tests for TypeBasedAggregationOperationContext.
Updated changelog, notice and readme. Upgraded to Spring Data Build parent 1.1.1.RELEASE. Upgraded to Spring Data Commons RC1. Switched to milestone repository. Updated links to the parts of the Spring Data Commons reference documentation.
Added test cases to ProjectionOperationUnitTests. Adjusted DSL for GroupOperation to be similar to ProjectionOperation. Introduced GroupOperationBuilder to GroupOperation to be able to define an alias for the current GroupOperation. Adjusted test cases in AggregationTests to the new DSL style accordingly. Added test cases to GroupOperationUnitTests for push and addToSet.
ProjectionOperationBuilder now implements AggregationOperation in order to be able support aliased as well as non alias projection operation expressions. Added test case for arithmetic operations to AggregationTests. Added Product domain class to be able to demonstrate some meaningful arithmetic operations. Applied changes from code review. Added internal private remove method to ProjectionOperation to allow previous operation to support aliasing.
Refined the way the aggregation pipeline gets rendered into a DBObject. More tests. Added $avg and shortcut methods to GroupOperations. Fixed ProjectionOperation to use 1 for implicit references. Made ProjectionOperation publicly visible. Added automatic result unwrapping. API consistency, tests, JavaDoc polish.
Added automatic field reference resolution which removes the need to have in depth knowledge on how aggregation steps structures the output.
Introduced AggregateOperationContext abstraction to hold the information of available fields for an aggregation step.
Introduced ContextConsumingAggregateOperation and ContextProducingAggregateOperation abstractions to be able to distinguish operations.
Updates test cases to reflect the API changes.
Added Zipcode sample dataset from 10gen. Allow Projections to be used in conjunction with GroupOperations. Integration & Refactoring of github contribution by Tobias Trelle and Sebastian Herold. Switched from builder-style to static factory based DSL construction of aggregation specifications. Introduced embedded DSL for convenient construction of aggregation specifications. Added test cases based on mongodb aggregation framework examples. Added more test cases, additional java doc. Added test case for unwind operation (returnFiveMostCommonLikes) in AggregationTests. Other test cases should now also run in CI environment, due to deterministic result ordering. Adjusted write concern to ensure persistence of sample data.
Introduced TypedAggregation which holds type information of the input type of an aggregation. Cleaned up aggregate methods on MongoOperations. Removed HasToDBObject interface. Cleaned up constructors for Aggregation and TypedAggregation.
Fixed parameter names in comments. Add static factory method. Implement basic aggregation operation join point. Implement match operation. Extracted ReferenceUtil. Created starting point of $group operation with _id field definition and $addToSet fields.
Fixed or added copyright headers where necessary. Added Tobias as author where necessary. Added @since tags to newly introduced classes and methods. Documented non-nullability of parameters. Polished test cases a bit.
Fluent interface for AggregationPipeline, tests. Added type safe versions for aggregation operations $match and $sort. Not null assertions + auto-prefix field in $unwind operation. Type safe impl for projections (first version). Support for $add and $substract in projection.
Added expireAfterSeconds attribute to @Indexed and @CompoundIndex annotations. Adapted MongoPersistentEntityIndexCreator to evaluate the attribute and configure the index about to be created if the attribute was configured to something non default.
Original pull request: #55.
Added restrict(…) method to the Query API that generates appropriate filter criteria to restrict the result to certain types only.
Type restrictions in query expressions are now applied in QueryMapper via a MongoTypeMapper based on information passed in through the query object in a "special" key. Exposed MongoTypeMapper in MongoConverter and MappingMongoConverter. Merged DefaultTypeMapper and DefaultMongoTypeMapper.
Original pull request: #53.
Added test case that shows that if a custom converter doesn't write type information on its own, the managed type can't be used in polymorphic scenarios. Direct type mappings still work as expected.
Added test case getHostNameShouldReturnServerNameReportedByMongo() to MongoMonitorIntegrationTests. Modified MongoMonitorIntegrationTests to use common mongo-infrastructure configuration. ServerInfo.getHostName() is now derived from serverStatus.serverUsed.
