mongo-c-driver 1.9.0

This version drops support for MongoDB 2.4 and adds support for MongoDB 3.6 features:

• New struct mongoc_change_stream_t to watch a collection for changes.
• New struct mongoc_client_session_t represents a MongoDB 3.6 session, which supports causal consistency: you are guaranteed to read your writes and to perform monotonic reads, even when reading from secondaries or in a sharded cluster.
• New functions that accept flexible options as a BSON document. These accept a "sessionId" option and any future options. In addition, the two new "update" functions accept the "arrayFilters" option that is new in MongoDB 3.6: mongoc_collection_insert_one mongoc_collection_insert_many mongoc_collection_update_one mongoc_collection_update_many mongoc_collection_replace_one mongoc_collection_delete_one mongoc_collection_delete_many mongoc_client_command_with_opts mongoc_database_command_with_opts mongoc_collection_command_with_opts mongoc_client_find_databases_with_opts mongoc_client_get_database_names_with_opts mongoc_collection_create_bulk_operation_with_opts mongoc_collection_find_indexes_with_opts mongoc_database_find_collections_with_opts mongoc_database_get_collection_names_with_opts
• New URI option "retryWrites=true" safely and automatically retries certain write operations if the server is a MongoDB 3.6 replica set or sharded cluster.
• Support for MongoDB OP_MSG wire protocol.

Additional changes not specific to MongoDB 3.6:

• Support for mongodb+srv URIs to query DNS for SRV and TXT records that configure the connection to MongoDB.
• Support LibreSSL with CMake build
• The "minPoolSize" URI option is deprecated: it's confusing and not useful.

Bug fixes:

• mongoc_bulk_operation_execute did not always initialize "reply".
• Fix C99 pedantic warnings.

php-mongodb 1.3.0 (PHP library)

This library is a high-level abstraction for the mongodb extension. This release adds support for new features in MongoDB 3.6 and drops support for MongoDB 2.4 and earlier.

Release Highlights

Version 1.4.0 of the mongodb extension introduced a new MongoDB\Driver\Session class to support client sessions for MongoDB 3.6. Session objects may be created via a new MongoDB\Client::startSession() method. All Client, Database, and Collection methods that communicate with the server now accept a "session" option. Presently, this option may be used for facilitating causally consistent reads. Sessions are not currently supported for GridFS operations.

MongoDB 3.6 introduced change streams, which allows applications to subscribe to all data changes on a collection (without manually tailing the oplog). Change streams are implemented using the aggregation framework and tailable cursors. This release adds support for change streams via a new MongoDB\Collection::watch() method, which returns a MongoDB\ChangeStream iterator. This iterator wraps a MongoDB\Driver\Cursor object and implements additional functionality, such as automatic resuming in the event of a dropped connection. A new tutorial on tailable cursor iteration has been added to the documentation, which is relevant for anyone working with tailable cursors or change streams.

Update methods (e.g. updateMany(), findOneAndUpdate()) now support an arrayFilters option, which may be used to specify which elements to modify in an array field. See Specify arrayFilters for Array Update Operations in the MongoDB manual for more information on this new feature.

MongoDB\Client::listDatabases() now supports a filter option, which may be used to filter which databases are returned when connected to MongoDB 3.6.

This release upgrades the mongodb extension requirement to 1.4.0. Support for MongoDB 2.4 and earlier has been removed.
