* $convert

* $toDate
* $toDecimal
* $toDouble
* $toInt
* $toLong
* $toObjectId
* $toString

Return false instead of null in isTransactionFailureCode(…)/isClientSessionFailureCode(…) to prevent null-dereference. Add initial size to HashMap instances with known number of elements. Fix typos in private constant names. Fix duplicate error code ids.
Original pull request: #592.
Use getRequiredPersistentEntity() instead of getPersistentEntity() for improved null-safety. Use Lombok to for required args constructors. Slightly tweak Javadoc.
Original pull request: #591.
Remove duplicate tests and fix assertions on existing ones. Move tests over to AssertJ and fix output database not applied correctly.

We now consider the output type (collection output) when rendering the MapReduce command. Previously, all output was returned inline without storing the results in the configured collection.
Original Pull Request: #588
We now convert collections that only contain UUID or byte array items to a BSON list that contains the encoded form of these items. Previously, we only converted single UUID and byte arrays into $binary so lists rendered to e.g. $uuid which does not work for queries.
Encoding is now encapsulated in strategy objects that implement the encoding only for their type. This allows to break up the conditional flow and improve organization of responsibilities.
We now support existsBy queries for reactive repositories to align with blocking repository support. ExistsBy support got lost during merging and is now back in place.
Extract boolean flag counting into BooleanUtil.
We now convert values of Map-like documents (Document, DBObject, Map) before writing these into MongoDB. Conversion got lost as result of a refactoring and missing tests.
We now make sure id properties used as persistence constructor arguments are no longer set via the property accessor, but during object instantiation. Previous to this change this caused an UnsupportedOperationException.

We're currently using application events to allow users to pre-process both entities and documents persisted via our …Template classes. That approach actually exposes a conceptual mismatch as events should be immutable and the hardly can be if event listeners try to modify the entity instance or even exchange them (in case the entity itself is immutable).
We now introduce an intermediate, package protected MappingMongoEvent.mapSource(…) that allows to exchange the source of the event. This is now used by the refined auditing infrastructure as this now returns the manipulated entity as it supports immutable ones as well. This will be removed as soon as we've come up with an alternative callback API that doesn't suffer from these conceptual mismatches (currently scheduled for release train Moore).
Persisting methods of MongoTemplate and SimpleMongoRepository now return potentially new object instances of immutable objects. New instances are created using wither methods/Kotlin copy(…) methods if an immutable object requires association with an Id or the version number needs to be incremented.

Prefix types with Querydsl and update visibility to allow construction of custom queries using SpringDataMongodbQuery. Reintroduce generics for JoinBuilder usage, fix warnings and nullability issues. Also add BsonValue types to simple types and use native BsonRegularExpression for regex conversion.
Add tests for "in" on dbref, exception translation, any embedded, join and lifecycle events related to DATAMONGO-362, DATAMONGO-595, DATAMONGO-700, DATAMONGO-1434, DATAMONGO-1810 and DATAMONGO-2010.

Adapt getResources(…) to use the file id and no longer the file name when opening a download stream. Add author tag. Add test to verify content retrieval by identity.
Original pull request: #581.
Using the file name leads to duplicate resource streams as file names are not unique therefore we're using the file's ObjectId to lookup the file content.
Original pull request: #581.
MongoCredentialPropertyEditor inspects now the connection URI for the appropriate delimiter tokens. Previously, inspection used the char questionmark for username/password delimiter inspection.
Original pull request: #578.
Make sure to place the LazyLoadingProxy early in the mapping process to avoid eager fetching of documents that might then get replaced by the LazyLoadingProxy.
Original Pull Request: #571
We now respect eager/lazy loading preferences of the annotated association property when the enclosing entity is created through its constructor and the reference is passed as constructor argument.
Previously, we eagerly resolved DBRefs and passed the resolved value to the constructor.
Original Pull Request: #571
Remove unused imports, deprecated MongoClientVersion methods for drivers no longer supported and remove their usage throughout the codebase and partially revert changes in MongoSimpleTypes because all org.bson types have been included in the 3.8 release of org.mongodb.bson.
Original Pull Request: #572
We now support reactive-only usage of Spring Data MongoDB without the need to use the synchronous driver or even having it on the class path. We conditionally register CodeWScope/CodeWithScope types that are bundled with the particular driver distributions.
NoOpDbRefResolver is now a top-level type to be used with a reactive-only MongoMappingContext.
Original Pull Request: #572
Simplify conditional flow. Replace AtomicReference construction in ChangeStreamEvent with AtomicReferenceFieldUpdater usage to reduce object allocations to streamline lazy body conversion usage. Tweak Javadoc and reference docs.
Original pull request: #576.
We still stick to count for non session operations as countDocuments does not allow geo operators like $near in the filter query. For now we will wait to see if this is resolved within the driver.
Added options to watch an entire database and resume the changestream from a given point in time (UTC).
Original pull request: #576.
Update Javadoc and add reference documentation.
Alter @Meta batchSize default to zero, as negative values bear a special meaning.
Along the lines remove deprecated driver method usage and add deprecations for options about the be removed in subsequent MongoDB server releases.
Original Pull Request: #575
We now allow configuration of the find cursor/find publisher batch sizes using Query.cursorBatchSize(…).
Configuring the batch size gives users more fine grained control over the fetch behavior especially in reactive usage scenarios as the batch size defaults in FindPublisher to the remaining demand. This can cause several roundtrips in cases the remaining demand is small and the emitted elements are dropped rapidly (e.g. using filter(…)).
On the repository level @Meta allows now configuration of the cursor batch size for derived finder methods.
interface PersonRepository extends Repository<Person, Long> {
@Meta(cursorBatchSize = 100)
Stream<Person> findAllByLastname(String lastname);
}

Allow open/close projection on return type for findAndReplace.
Use default methods for delegation and remove collation from FindAndRemoveOption in favor of the collation set on the query itself.
Update Javadoc and reference documentation.
Original Pull Request: #569
Use diamond syntax in imperative and reactive Template API implementations. Rename ReactiveMongoTemplate.toDbObject to toDocument. Move Terminating interfaces in ExecutableUpdateOperation and ExecutableRemoveOperation to the top-most position to align with other fluent interface declarations and to improve discoverability of terminating operations.
Convert ReactiveMongoTemplateTests assertions to AssertJ.
Original Pull Request: #569
We now support findAndReplace operations through the imperative and reactive Template API to find an object by a query and entirely replace it (except for the _id).
template.findAndReplace(query(where("name").is("Han")), new Person("Luke"))
template.update(Person.class).inCollection(STAR_WARS).matching(query(where("name").is("Han"))).replaceWith(luke).findAndReplace()
Original Pull Request: #569
Add nullability annotation to MongoParameterAccessor.getPoint(). Remove superfluous casts.
Convert MongoQueryCreatorUnitTests to user AssertJ assertions.
