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 following MongoDB 3.4 aggregation operators:
$indexOfBytes, $indexOfCP, $split, $strLenBytes, $strLenCP, $substrCP, $indexOfArray, $range, $reverseArray, $reduce, $zip, $in, $isoDayOfWeek, $isoWeek, $isoWeekYear, $switch and $type.

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 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"))

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.

Reactive MongoDB repository can now be composed from Project Reactor and RxJava types for method arguments and return types. Query methods and methods from the base/implementation classes can be invoked with a conversion of input/output types.
Favor usage of List over BasicDBList.
Rename ProjectionOperation.transform to applyCondition.
Add missing author and since tags, remove trailing white spaces and fix reference documentation headline clash.

We now support $cond and $ifNull operators for projection and grouping operations. ConditionalOperator and IfNullOperators are AggregationExpressions that can be applied to transform or generate values during aggregation.
TypedAggregation<InventoryItem> agg = newAggregation(InventoryItem.class,
project().and("discount")
.transform(ConditionalOperator.newBuilder().when(Criteria.where("qty").gte(250))
.then(30)
.otherwise(20))
.and(ifNull("description", "Unspecified")).as("description")
);
corresponds to
{ "$project": { "discount": { "$cond": { "if": { "$gte": [ "$qty", 250 ] },
"then": 30, "else": 20 } },
"description": { "$ifNull": [ "$description", "Unspecified"] }
}
}

We added methods to set values for $caseSensitive and $diacriticSensitive when using TextCriteria. Both operators are optional and will not be used until explicitly set.
// { "$text" : { "$search" : "coffee" , "$caseSensitive" : true } }
TextCriteria.forDefaultLanguage().matching("coffee").caseSensitive(true);
// { "$text" : { "$search" : "coffee" , "$diacriticSensitive" : true } }
TextCriteria.forDefaultLanguage().matching("coffee").diacriticSensitive(true);

Update Spring Framework documentation links to point always to the Spring Framework version specified in the pom, where possible. Mention $lookup in aggregation.
Original Pull Request: #349
We now support @AliasFor to build composed annotations with: @Document, @Id, @Field, @Indexed, @CompoundIndex, @GeoSpatialIndexed, @TextIndexed, @Query, and @Meta. Added missing license header to @Field.

We now distinguish between aggregation operations that replace fields in the aggregation pipeline and those which inherit fields from previous operations. InheritsFieldsAggregationOperation is a nested interface of FieldsExposingAggregationOperation is a marker to lookup fields along the aggregation context chain. Added unit and integration tests. Mention lookup operator in docs.
