Rename InfiniteStream annotation to Tailable to reflect the related MongoDB approach used for repository query methods returning an infinite stream. InfiniteStream is the high-level concept that is achieved by using tailable cursors.

Rename ICULocale to CollationLocale. Introduce interface for ComparisonLevel construction and let ICUComparisonLevel types implement that interface. Make value types immutable where possible. Provide static instances for default comparison level instances.
Replace collation conversion IndexConverters with Collation.from(…).toMongoCollation() converter. Introduce missing generic types. Replace Optional.get() with Optional.map(…).orElse(…).
Update reference documentation.

Fix documentation for namespace types. Remove unused ReflectiveDBCollectionInvoker. Simplify tests, align bean name to mongoClient. Remove injection of Mongo in favor of injecting MongoTemplate.
Remove throws declaration from AbstractMongoConfiguration.mongoClient(). MongoClient creation does not throw checked exceptions so throwing an Exception is no longer required. Replace Mongo by MongoClient in reference documentation.

Remove and replace usage of "mongo" by "mongoClient". This involves xsd schema, bean names, constructor and parameter types. This required some API changes as some server commands are no longer directly available through the api, but have to be invoked via runCommand.
Also remove references to outdated API using Credentials and an authentication DB instead of MongoCredentials for authentication.
Updated and removed (unused) tests; Altered documentation.

Move aggregation options conversion to AggregationOptions.getMongoAggregationOptions(). Allow cursor options to control cursor batch size. Add command logging to stream execution. Rearrange method order. Close cursor in tests. Change author name from user name to full name.

Support Decimal128 as Mongo simple type if present. Decimal128 is stored as NumberDecimal.
class Person {
String id;
Decimal128 decimal128;
Person(String id, Decimal128 decimal128) {
this.id = id;
this.decimal128 = decimal128;
}
}
mongoTemplate.save(new Person("foo", new Decimal128(new BigDecimal("123.456"))));
is represented as:
{ "_id" : "foo", "decimal128" : NumberDecimal("123.456") }
Extend year range in license headers. Use MongoDB JSON serializer for String escaping. Move unquoting/quote checking to inner QuotedString utility class. Reformat code.
Field projections now expose their fields as synthetic simple fields. Projection aggregation stage redefines the available field set available for later aggregation stages entirely so projected fields are considered synthetic. A simple synthetic field has no target field which causes later aggregation stages to not pick up the underlying target but the exposed field name when rendering aggregation operations to Mongo documents.
The change is motivated by a bug where previously an aggregation consisting of projection of an aliased field and sort caused the sort projection stage to render with the original field name instead of the aliased field. The sort did not apply any sorting since projection redefines the available field set entirely and the original field is no longer accessible.

Reformat code according to Spring Data style. Add test for authenticated use. Add JavaDoc to newly introduced methods. Allow configuration of an authentication database. Update reference documentation.

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.
