mongo-c-driver 1.15.2

I'm pleased to announce version 1.15.2 of libbson and libmongoc,
the libraries constituting the MongoDB C Driver.

libbson

No changes since 1.15.1; release to keep pace with libmongoc's version.

libmongoc

Bug fixes:

Prevent mongoc_transaction_opts_set_max_commit_time_ms from applying to subsequent transactions that should be using the default.
Do not report the initial error if a retry for a change stream function (mongoc_collection_watch, mongoc_database_watch, or mongoc_client_watch) succeeds

libbson

No change since 1.15.0; released to keep pace with libmongoc's version.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.15.1.

Bug fixes:

Fix change stream resume logic when no documents received
Reduce the required cmake version to build with zstd support
Minor fixes to mongos pinning logic
Do not resume a change stream on NonResumableChangeStreamError

libbson

No change since 1.14.1; released to keep pace with libmongoc's version.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.15.0. This release adds
support for MongoDB 4.2 features.

Features:

Support for sharded transactions on MongoDB sharded clusters 4.2+.
Add convenient transaction runner (mongoc_client_session_with_transaction),
which accepts a callback and performs appropriate retry logic.
Add a new transaction option to specify maximum time to wait for a commit,
mongoc_transaction_opts_set_max_commit_time_ms.
Add URI option "retryReads=true" safely and automatically retries certain
read operations if the server is a MongoDB 3.6+. Note, this may require applications to adjust any custom retry logic to prevent inadvertently retrying for too long
Poll SRV records to mongos servers periodically.
Keep connections alive after a primary stepdown detected.
Standardizes URI options supported across all spec-compliant MongoDB drivers.
"retryWrites" URI option now defaults to true (requires crypto for session
support).
Send any aggregate with $out or $merge stage to a primary.
Add the ability to specify an aggregate pipeline as an update document.
Add a database aggregate helper, mongoc_database_aggregate.
Add option for change streams, "startAfter".
Add mongoc_change_stream_get_resume_token, which returns the resume token
which should be used to resume a change stream.
Add support for zstd compression.

Bug fixes:

Correctly report an error in mongoc_change_stream_next if the resume token
(_id) is not a document. Previously, an error was only reported if the
field was missing.
Fix mongoc_collection_update with MONGOC_UPDATE_MULTI_UPDATE,
mongoc_collection_remove, and mongoc_collection_delete when retryWrites
was enabled. They would fail previously.
Command options are now correctly taken into account when batching bulk
writes for OP_QUERY. It was possible to exceed the maximum document size
before.
Fix a crash if a multi-batch bulk write with OP_MSG errored on a batch.

libbson

It is my pleasure to announce libbson 1.14.1.

Bug fixes:

Remove unnecessary dependencies from pkg-config.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.14.1.

Bug fixes:

Prohibit starting a transaction for pre-4.0 MongoDB servers.
Prohibit starting a sharded transaction for pre-4.2 MongoDB servers.

libbson

It is my pleasure to announce libbson 1.14.0.

Features:

ObjectIDs are generated in compliance with the driver ObjectID spec.
Add a bson_copy_to_excluding_noinit variant taking a va_list.
Add example of validating BSON nesting depth with bson_visitor_t.

Bug fixes:

Relaxed JSON pads datetime milliseconds with spaces instead of zeroes.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.14.0.

Features:

Support for OpenSSL 1.1.1 and its implementation of TLS v1.3.
New function mongoc_stream_should_retry.
New accessor mongoc_server_description_last_update_time.
New method mongoc_client_reset to be called after forking.

Bug fixes:

OP_MSG with unacknowledged writes (write concern of w:0) would serialize
incorrectly on big-endian platforms, causing writes to use the default
write concern of w:1.
mongoc_collection_update_many and mongoc_collection_delete_many would fail
with the URI option retryWrites=true.
In a transaction, the driver now properly ignores the readConcern configured
on a client, database, or collection: only the mongoc_transaction_opt_t's
readConcern is used.
Remove timestamp from uninstall scripts to permit reproducible build.
Setting mongoc_ssl_opt_t.pem_file or ca_file to a bad file path caused a
hang with Darwin SSL.
Fix the ENABLE_SASL cmake option:
- Remove unnecessary GSSAPI value. It was equivalent to specifying ENABLE_SASL=CYRUS.
- ENABLE_SASL=AUTO now correctly chooses SSPI on Windows instead of CYRUS.
The client pool failed to set proper apm callbacks for clients created
via try_pop().

libbson

It is my pleasure to announce libbson 1.13.1.

Bug fixes:

Separate libmongoc and libbson uninstall scripts so they do not overwrite
each other.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.13.1.

Bug fixes:

mongoc_collection_update_many and mongoc_collection_delete_many would fail
with the URI option retryWrites=true.
Remove timestamp from uninstall scripts to permit reproducible build.
Add missing header files to the release tarball to fix compilation when
configuring with ENABLE_SASL=GSSAPI.
Separate libmongoc and libbson uninstall scripts so they do not overwrite
each other.
Fix running make install with DESTDIR.

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:

Fix crash when iterating corrupt BSON.

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.

libbson

It is my pleasure to announce libbson 1.12.0. This release deprecates all
MD5-related public APIs; they will be removed in the next major release.

Bug fixes:

Properly handle zero-length BSON binary values
Fix crash parsing Base64-encoded data in JSON when using libbson without
libmongoc

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.12.0.

Features:

New function mongoc_client_session_in_transaction to check if a multi-
document transaction is started.
New examples for change streams and transactions, improved guide for
migrating from mongoc_collection_count to mongoc_collection_count_documents

Bug fixes:

Fix occasional crash in sharded queries
Retry all retryable write concern errors
mongoc_client_session_commit_transaction sets the correct error label when
the primary is unavailable
mongoc_collection_find_with_opts had prohibited read preference "primary"
in a transaction
mongoc_collection_aggregate had not inherited its mongoc_collection_t's
read preference; only an explicitly provided read preference was used.
Allow unencoded delimiters in username/password if unambiguous

libbson

It is my pleasure to announce libbson 1.11.0. This version adds the following
features and improvements:

All "destroy" functions such as bson_destroy or bson_reader_destroy now
ignore a NULL argument.
Replace MD5 with FNV-1a hash to generate ObjectIds (for FIPs compliance).

Bug fixes:

Functions incorrectly marked with the "const" compiler attribute are now
marked as "pure", fixes build error when link-time optimization is enabled.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.11.0. This release adds
support for MongoDB 4.0 features. It includes the following additions and
improvements:

Multi-document transactions, see mongoc_client_session_start_transaction
New function mongoc_error_has_label to check for specific error labels such
as "TransientTransactionError" or "UnknownTransactionCommitResult" in
error replies.
New functions to subscribe to changes on an entire client or database:
- mongoc_client_watch
- mongoc_database_watch
New option for change streams, "startAtOperationTime".
mongoc_collection_count_with_opts is deprecated for two new functions:
- mongoc_collection_count_documents
- mongoc_collection_estimated_document_count
Support for SCRAM-SHA-256 authentication, including support for non-ASCII
passwords using libicu is an optional dependency.
Faster mongoc_database_get_collection_names_with_opts fetches only names,
not the entire collection metadata.

Additional changes not specific to MongoDB 4.0:

All "destroy" functions such as mongoc_collection_destroy now ignore a NULL
argument.
The driver now returns an error if you attempt to use "arrayFilters" in an
update with a MongoDB server older than 3.6.
Update functions include a new "upsertedCount" field in the reply document.
Replace MD5 with FNV-1a hash to generate ObjectIds (for FIPs compliance).

Bug fixes:

Functions incorrectly marked with the "const" compiler attribute are now
marked as "pure", fixes build error when link-time optimization is enabled.

libbson

No change since 1.10.2; released to keep pace with libmongoc's version.

libmongoc

It is my pleasure to announce the MongoDB C Driver 1.10.3. This release fixes
