We now set autogenerated Ids in Maps that are used as top-level entities. This allows transparent and persistent Map usage without requiring to use Document in application code. Previously, we only set autogenerated Ids in Document and persistent entity types.

Remove client side operating system check as operating system-dependant constraints depend on the server. Add check on whitespaces. Add author tags. Extend tests.
Adapt check in SimpleReactiveMongoDatabaseFactory accordingly. Remove superfluous UnknownHostException declaration in reactive database factory. Replace references to legacy types in Javadoc with references to current ones.
Original pull request: #546.
Remove unused final keywords from method parameters and unused variables. Add nullable annotations to parameters that can be null. Fix generics.
Original pull request: #547.
Remove DateFactory and split up tests.
Introduce dedicated Timezone abstraction and update existing factories to apply the timezone if appropriate. Update builders and align code style.

We now render to the correct UUID representation in String-based queries. Unquoted values render to $binary representation, quoted UUIDs are rendered with their toString() value.
Previously we used JSON.serialize() to encode values to JSON. The com.mongodb.util.JSON serializer does not produce JSON that is compatible with Document.parse. It uses an older JSON format that preceded the MongoDB Extended JSON specification.

Add since tag. Add non-null guard. Refactor conditional resource mapping to Optional. Apply code formatter.
Optimize array construction from List.
Original pull request: #543.
We now provide GridFsOperations.getResource(GridFSFile) to create GridFsResource without a database lookup. This allows direct creation of GridFsResource for GridFSFile.
Original pull request: #543.
We now no longer emit an exception via SimpleReactiveMongoRepository.findOne(Example) if the query completes without yielding a result. Previously findOne(Example) emitted a NoSuchElementException if the query returned no result.

Turn instance methods into static ones where applicable. Avoid parameter type array cloning where possible.
Add reference to rework stack-trace inspection in order to throw ClientSessionException. Migrate MongoPersistentEntityIndexCreatorUnitTests to AssertJ. Add tests to verify simple session proxy wrapping on subsequent MongoDbFactory.withSession(…) calls.
Guard ClientSession tests with replica set rule. Remove unused code. Add non-null guards. Add missing Nullable annotations. Slightly tweak Javadoc and reference documentation.
Original pull request: #536.
We now support ClientSession via MongoOperations and ReactiveMongoOperations. Client sessions introduce causal consistency and retryable writes. A client Session can be either provided by application code or managed by specifying ClientSessionOptions. Binding a ClientSession via MongoOperations.withSession(…) provides access to a Session-bound MongoOperations instance that associates the session with each MongoDB operation.
ClientSession support applies only to MongoOperations and ReactiveMongoOperations and is not yet available via repositories.
ClientSession session = client.startSession(ClientSessionOptions.builder().causallyConsistent(true).build());
Person person = template.withSession(() -> session)
.execute(action -> {
action.insert(new Person("wohoo"));
return action.findOne(query(where("id").is("wohoo")), Person.class);
});
session.close();

Switched to ClassUtils.isAssignableValue(…) in getPotentiallyConvertedSimpleRead(…) as it transparently handles primitives and their wrapper types so that we can avoid the superfluous invocation of the converter infrastructure.
We now export composable repositories through our CDI extension. Repositories can now be customized either by a single custom implementation (as it was before) and by providing fragment interfaces along their fragment implementation.
This change aligns CDI support with the existing RepositoryFactory support we provide within a Spring application context.
We previously used MongoTemplate.insertAll(…) which determines the collection to insert the individual elements based on the type, which - in cases of entity inheritance - will use dedicated collections for sub-types of the aggregate root. Subsequent lookups of the entities will then fail, as those are executed against the collection the aggregate root is mapped to.
We now rather use ….insert(Collection, String) handing the collection of the aggregate root explicitly.
Extend copyright license years. Slightly reword documentation. Use IntStream and insertAll to create test fixture.

We now use _id lookup for remove operations that query with limit or skip parameters. This allows more fine grained control over documents removed.

Related pull request: #531.
We now use AbstractMongodbQuery.fetch() instead of AbstractMongodbQuery.fetchResults() to execute MongoDB queries. fetchResults() executes a find(…) and a count(…) query. Retrieving the record count is an expensive operation in MongoDB and the count is not always required. For regular find(…) method, the count is ignored, for paging the count(…) is only required in certain result/request scenarios.
Original Pull Request: #529
We now return the first result when executing findFirst/findTop queries. This fixes a glitch introduced in the Kay release throwing IncorrectResultSizeDataAccessException for single entity executions returning more than one result, which is explicitly not the desired behavior in this case.
Original pull request: #530.
We now avoid calling ….inCollection(…) with a fixed, one-time calculated collection name to make sure we dynamically resolve the collections. That's necessary to make sure SpEL expressions in @Document are evaluated for every query execution.
