I'm pleased to announce version 1.13.0 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.

libbson

It is my pleasure to announce libbson 1.13.0.

Features:

New functions to save and restore progress of a bson_iter_t:
bson_iter_key_len, bson_iter_offset, and bson_iter_init_from_data_at_offset
Additional functions bson_iter_overwrite_date_time, bson_iter_overwrite_oid,
and bson_iter_overwrite_timestamp. All fixed-length BSON values can now be
updated in place.

Bug fixes:

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.13.0.

Features:

Report a new error code, MONGOC_ERROR_GRIDFS_CORRUPT, when a chunk larger
than chunkSize is detected. Before, the driver had crashed with an assert.
Restructure of install directory. All mongoc headers are under mongoc/
and all bson headers are under bson/. The preferred way of including the
headers are mongoc/mongoc.h and bson/bson.h respectively.
Forwarding headers in the root are provided for backwards compatibility.
The default CMake build type had been unspecified, now it is RelWithDebInfo.
Support LibreSSL 2.7+.

Bug fixes:

mongoc_collection_replace_one is now a correctly exported symbol.
Fix multiple issues with readConcern and writeConcern inheritance.
Fix rare crash with mongodb+srv URIs on Windows.
mongoc_gridfs_create_file_from_stream ignored errors while writing chunks
to the server.
The following functions should not have taken a "bypassDocumentValidation"
option in bson_t *opts, the option is now prohibited:
- mongoc_bulk_operation_insert_with_opts
- mongoc_bulk_operation_update_one_with_opts
- mongoc_bulk_operation_update_many_with_opts
- mongoc_bulk_operation_replace_one_with_opts
The heartbeat-succeeded and heartbeat-failed events (part of SDAM
Monitoring) had uninitialized "duration" fields, they are now set correctly.
