MongoDB 4.0 digests passwords by default which does not work with the SCRAM-SHA-256 authentication method so we skip those tests when running against MongoDB 4.0.
We now allow usage of $sample as aggregation framework stage and are no longer in the way with Query by Example. Previously, we identified Example objects using the $sample keyword which prevented query mapping of aggregation pipelines that contained a sample stage.
We already fixed this issue via DATAMONGO-1325 for the 2.x line.

MongoCredentialPropertyEditor inspects now the connection URI for the appropriate delimiter tokens. Previously, inspection used the char questionmark for username/password delimiter inspection.

For Criteria instances that use regular expressions we now properly compare the two Pattern instances produced by also including the pattern flags in the comparison.
We now initialize a TypeBasedAggregationOperationContext for TypedAggregations if no context is provided. This makes sure that potential Criteria objects are run trough the QueryMapper.
In case the default context is used we now also make sure to at least run the aggregation pipeline through the QueryMapper to avoid passing on non MongoDB simple types to the driver.

Match exactly for either top-level properties of leaf-properties instead of accepting the property/field name suffix. Downgrade tests to use DBObject API.

We now follow the conversion rules for id properties with a valid ObjectId representation when creating queries. Prior to this change e.g. String values would have been turned into ObejctIds when saving a document, but not when querying the latter.

Full editing pass of the Spring Data MongoDB reference guide. I also adjusted index.adoc to work with the changes I made to the build project, so that we get Epub and PDF as well as HTML.
