mongodb/mongo-c-driver 1.9.0 on GitHub

It is my pleasure to announce 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:

Thanks to everyone who contributed to the development of this release.

Peace,
