Breaking changes

This version contains a major rename that affects almost everything in the DSL module. To learn more about the reasons we did it, see #35 and !54. Although future versions may still have breakages, this was the last planned major change.

  • Renamed package models to command
  • Renamed package expr to query
  • Moved contents of package expr.common to tree
  • Moved contents of package options to command
  • Moved contents of package options.common to command
  • Renamed FilterOperators to FilterQuery, removed FilterExpression
  • Renamed PredicateOperators to FilterQueryPredicate, removed PredicateExpression
  • Renamed UpdateOperators to UpdateQuery, removed UpdateExpression
  • Renamed UpsertOperators to UpsertQuery
  • Renamed Expression (and its hierarchy) to BsonNode
  • Renamed ValueDsl to AggregationOperators

BSON

  • Added Bson.read() and BsonArray.read() to access contents of BSON objects (!50)
  • Added BsonContext.readDocument() and BsonContext.readArray() to convert from the binary BSON representation to driver objects (!50)

0.13.0 • Arbitrary BSON writers and parsers

BSON

The :bson module's documentation on the Kotlin MongoDB driver has been removed.

There are multiple breaking changes related to this refactor. For example, buildBsonDocument and buildBsonArray are now members of BsonContext instead of being top-level functions.

  • Everything but the interface definitions for arbitrary BSON writers and parsers has been removed from the :bson module
  • The BSON parser and writer based on the Kotlin MongoDB driver has been moved to the new module :bson-official (67567b42)
  • BSON tests for parsers and writers have been moved to the new module :bson-tests (5bef8c13)
  • Support most Kotlin platforms (9af59a3b)

Annotations

  • Support most Kotlin platforms (9af59a3b)

DSL

  • Utilities related to the official MongoDB driver have been moved to the :driver-shared-official internal module (404cbb38)

Documentation

  • Changed the Maven metadata from linking to the repository to linking to the documentation website (8ca2a2df)
