We now support the $replaceRoot stage in aggregation pipelines. $replaceRoot can reference either a field, an aggregation expression or it can be used to compose a replacement document.
newAggregation(
replaceRoot().withDocument()
.andValue("value").as("field")
.and(MULTIPLY.of(field("total"), field("discounted")))
);
newAggregation(
replaceRoot("item")));

We now support the $count stage in aggregation pipelines.
newAggregation(
match(where("hotelCode").is("0360")),
count().as("documents"));

Added MongoDB 3.4 profile to pom.xml and upgraded to MongoDB 3.4 on travis-ci.
Delete assertion checking property that has been removed in MongoDB 3.4 (see: https://jira.mongodb.org/browse/SERVER-24928)
We now support the following MongoDB 3.4 aggregation operators:
$indexOfBytes, $indexOfCP, $split, $strLenBytes, $strLenCP, $substrCP, $indexOfArray, $range, $reverseArray, $reduce, $zip, $in, $isoDayOfWeek, $isoWeek, $isoWeekYear, $switch and $type.

Use InheritingExposedFieldsAggregationOperationContext instead of anonymous context class for condition mapping. Drop aggregation input collections before tests. Minor reformatting.
Original pull request: #417.
We now support $let in aggregation $project stage.
ExpressionVariable total = newExpressionVariable("total").forExpression(ADD.of(field("price"), field("tax")));
ExpressionVariable discounted = newExpressionVariable("discounted").forExpression(Cond.when("applyDiscount").then(0.9D).otherwise(1.0D));
newAggregation(Sales.class,
project()
.and(define(total, discounted)
.andApply(MULTIPLY.of(field("total"), field("discounted"))))
.as("finalTotal"));
Original pull request: #417.
Renamed CondOperator to Cond and IfNullOperator to IfNull. Both conditional operations are now available from ConditionalOperators.when and ConditionalOperators.ifNull and accept AggregationExpressions for conditions and values.
Original Pull Request: #421
We now also accept CriteriaDefinition next to Criteria for Aggregation.match. The existing match(Criteria) method remains to preserve binary compatibility.
Add property to field name mapping for Sort orders by moving Sort mapping to UpdateMapper. Fix typo. Add JavaDoc. Reformat code. Remove trailing whitespaces.
Original pull request: #405.
Renamed @Count and @Delete to @CountQuery and @DeleteQuery. Minor polishing in test cases and test repository methods. JavaDoc, formatting.
Original pull request: #416.
Introducing dedicated annotations for manually defined count and delete queries to avoid misconfiguration and generally simplifying the declaration.

Add missing transformations for ConstructorReference, OperatorNot, OpNE, OpEQ, OpGT, OpGE, OpLT, OpLE, OperatorPower, OpOr and OpAnd. This allows usage of logical operators &, || and ! as part of the expression, while ConstructorReference allows instantiating eg. arrays via an expression `new int[]{4,5,6}`. This can be useful eg. comparing arrays using $setEquals.
More complex aggregation operators like $filter can be created by defining the variable references as string inside the expression like filter(a, 'num', '$$num' > 10).
Commands like $let requires usage of InlineMap to pass in required arguments like eg. let({low:1, high:'$$low'}, gt('$$low', '$$high')).

We now directly support comparison aggregation operators ($cmp, $eq, $gt, $gte, $lt, $lte and $ne) on both group and project stages.
Original pull request: #414.
We new support $filter in aggregation pipeline.
Aggregation.newAggregation(Sales.class,
Aggregation.project()
.and(filter("items").as("item").by(GTE.of(field("item.price"), 100)))
.as("items"))
Original pull request: #412.
Just added overloads for stdDevSamp and stdDevPop taking AggregationExpression and updated the doc.
Also replaced String operation based MongoDB operation building by using operators directly.
Original Pull Request: #360
Adopt type hint assertion for existing _class field checks. Simplify test code to use Collections.singletonList instead of Arrays.asList. Replace BasicDBList with List in JavaDoc. Use type inference for DocumentTestUtils.getAsDBList to avoid casts in test code. Extend documentation.
Original pull request: #411.
Always add type hint as last property of a Document.
This is necessary to assure document equality within MongoDB in cases where the query contains full document comparisons. Unfortunately this also might break existing stuff since the order of properties within a Document is changed with this commit.
Original pull request: #411.
We now use the newly introduced ….useRepositoryConfiguration(…) in the module specific RepositoryConfigurationExtension implementations to distinguish between reactive and non-reactive repositories.
Removed RepositoryType class as it was only used by the previous repository typ detection.
