The previous implementation of MongoTemplate.doSaveVersioned(…) prematurely initialized the version property so that the entity wasn't considered new by the auditing subsystem. Even worse, for primitive version properties, the initialization kept the property at a value of 0, so that the just persisted entity was still considered new. This mean that via the repository route, inserts are triggered even for subsequent attempts to save an entity which caused duplicate key exceptions.
We now make sure we fire the BeforeConvertEvent before the version property is initialized or updated. Also, the initialization of the property now sets primitive properties to 1 initially.
Added integration tests for the auditing via MongoOperations and repositories.
We now defensively create a List rather than a LinkedHashSet (which Spring's CollectionFactory.createCollection(…) defaults to) to make sure we're not accidentally dropping values that are considered equal according to their Java class definition.
Replace duplicate checks to ClientSession.hasActiveTransaction() with MongoResourceHolder.hasActiveTransaction(). Introduce MongoResourceHolder.getRequiredSession() to avoid nullability warnings.

Introduce FieldType to express the desired field type to use for MongoDB Id conversion. Adapt Querydsl Id conversion so Id values are converted in the QueryMapper and no longer in SpringDataMongodbSerializer.
Adapt tests. Move MongoId from o.s.d.mongodb to o.s.d.m.c.core. Javadoc, reference docs.

@MongoId allows more fine grained control over id conversion by specifying the intended id target type. This allows to skip the automatic to ObjectId conversion of values that happen to be valid ObjectId hex strings.
public class PlainStringId {
@MongoId String id; // treated as String no matter what
}
public class PlainObjectId {
@MongoId ObjectId id; // treated as ObjectId
}
public class StringToObjectId {
@MongoId(FieldType.OBJECT_ID) String id; // treated as ObjectId if the value is a valid ObjectId hex string
}

Add fix for bound reified type in fluent MapReduce operations.
Also add missing reified type extension to FindDistinct with projection.

We now fixed Kotlin extension generics to properly use projections by ignoring the source type of the Fluent API object. Previously, the source and target type were linked which prevented the use of a different result type.
Original Pull Request: #609
Using the fluent API allows using DTO projections with properties that are unknown to the actual domain object. Previously, DTO projections attempted to read the domain type and during property access, missing properties were reported with an IllegalArgumentException. Unknown properties remain now unset.

We now support queries to return a tailable cursor using the fluent reactive API.
query(Human.class)
.inCollection("star-wars")
.as(Jedi.class)
.matching(query(where("firstname").is("luke")))
.tail();
Original Pull Request: #608
Move and enhance tailable cursor documetation. Move to separate file, preserve anchor and add imperative way using a MessageListener.
Add additional notes on usage of com.mongodb.client.MongoClient.

We now redeclare the Asciidoctor Maven plugin to register the store specific attributes. Apparently they must not contain dots, so we replaced them with dashes.
