Next Release
============
Features:
*
Bug fixes:
*
mongo-c-driver 1.14.0
=====================
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().
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.13.1
=====================
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.
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.13.0
=====================
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.
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.12.0
=====================
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
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.11.0
=====================
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.
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.10.3
=====================
No change since 1.10.2; released to keep pace with libbson's version.
-- A. Jesse Jiryu Davis
mongo-c-driver 1.10.2
=====================
It is my pleasure to announce the MongoDB C Driver 1.10.2. This release fixes
the libbson and libmongoc installed library filenames and SONAMEs on Linux.
They had changed unintentionally with the switch to CMake in 1.10.0; they are
now consistent with 1.9.x and previous releases. Thanks to Roberto C. Sánchez
for the fix.

mongo-c-driver 1.10.1
=====================
It is my pleasure to announce the MongoDB C Driver 1.10.1. This release fixes
the following bugs introduced in version 1.10.0:
* Client sessions were not prohibited with unacknowledged write concern and
mongoc_bulk_operation_execute; now they are prohibited. Client sessions have
been prohibited with all other unacknowledged writes since 1.10.
* The "arrayFilters" update option, new in MongoDB 3.6 and supported since
libmongoc 1.9.0, was inadvertently prohibited by
mongoc_bulk_operation_update_one_with_opts and
mongoc_bulk_operation_update_many_with_opts in 1.10. The option is now
permitted again.
* The mongoc-stat tool for displaying shared counters was disabled on Linux
and not installed; it is now restored.
Thanks to everyone who contributed to the development of this release.

mongo-c-driver 1.10.0
=====================
It is my pleasure to announce MongoDB C Driver 1.10.0. This version drops
support for MongoDB 2.6 and adds the following features and bugfixes:
* libbson and libmongoc are now maintained in the mongo-c-driver repository,
although they are still built as separate libraries, and libbson can still
be used without libmongoc.
* Building libbson and libmongoc now requires CMake on all platforms. The
Autotools build scripts ("configure" and related scripts) have been deleted.
See the "installing" page for updated instructions, including the new
ENABLE_MONGOC option and changes to the ENABLE_BSON option.
* IPv6 is now fully supported and conforms to RFC-6555. If a hostname has both
IPv4 and IPv6 DNS records, the driver tries connecting with IPv6 first. If a
connection can't be established after 250ms then IPv4 is tried in parallel.
Whichever succeeds connection first cancels the other. The successful DNS
result is cached for 10 minutes.
* If CMake is configured with ENABLE_SSL=AUTO (the default), libmongoc now
uses native TLS libraries on Mac and Windows, and OpenSSL everywhere else.
Before, it would search for OpenSSL on all platforms and only use native
TLS on Mac and Windows as a fallback.
* The driver now handshakes SSL connections to multiple servers in a replica
set or sharded cluster in parallel, so long as it uses OpenSSL or Windows
SChannel. (SSL handshakes with Apple's Secure Transport are still serial.)
A larger receive buffer with SChannel increases performance over slow
connections.
* All functions that accept read concern now prohibit it, if MongoDB is too
old to support it (MongoDB 3.0).
* Client sessions are now prohibited with unacknowledged writes.
* mongoc_collection_find_and_modify_with_opts now prohibits write concern if
MongoDB is too old to support it (MongoDB 3.0).
* Other helper functions for commands that write, now prohibit write concern
if MongoDB is too old to support it (pre-3.4):
mongoc_client_read_write_command_with_opts
mongoc_client_write_command_with_opts
mongoc_collection_read_write_command_with_opts
mongoc_collection_write_command_with_opts
mongoc_database_read_write_command_with_opts
mongoc_database_write_command_with_opts
mongoc_collection_aggregate with $out
mongoc_collection_drop_index_with_opts
mongoc_collection_drop_with_opts
mongoc_collection_rename_with_opts
mongoc_database_drop_with_opts
Write concern behavior is unchanged for regular CRUD functions.
* Setting a negative writeConcern level of -2 or smaller, via the "opts"
parameter to functions that accept BSON options, is now prohibited. The
special "w" values -2 through -4 are only used internally. The deprecated
"w=-1" is still allowed, as a synonym for "w=0".
* The Kerberos URI option authMechanismProperties=CANONICALIZE_HOST_NAME:true
is now implemented with the Windows Kerberos provider, SSPI.
* This repository now includes GDB and LLDB customizations for pretty-printing
bson_t structs as JSON while debugging. See the "debugging" page.
* The internal preprocessor symbol HAVE_STRINGS_H has been renamed
BSON_HAVE_STRINGS_H. If you maintain a handwritten bson-config.h you must
rename this symbol.
* The following helper functions do not work with mongoc_client_session_t,
they are deprecated in favor of running MongoDB commands directly with a
function like mongoc_client_read_command_with_opts:
mongoc_client_get_server_status
mongoc_collection_stats
mongoc_collection_validate
* mongoc_cursor_is_alive is now deprecated for mongoc_cursor_more, which is
functionally equivalent.

mongo-c-driver 1.9.5
====================
It is my pleasure to announce mongo-c-driver 1.9.5. This release fixes the following bugs:
* New change streams API functions were not marked extern "C"
* mongoc_collection_watch now accepts a pipeline argument as a BSON array, in
addition to accepting a BSON document with a "pipeline" array field
* Crashes in several change stream error handling paths
* Commands could return false with an empty bson_error_t after a replica set
reconfig
* Network error messages omitted the command name when using OP_MSG
Thanks to everyone who contributed to the development of this release.

-- A. Jesse Jiryu Davis
mongo-c-driver 1.9.1
====================
It is my pleasure to announce mongo-c-driver 1.9.1. This release fixes a bug
that caused session ID to be included in authentication and server monitoring
commands. Thanks to Jeremy Mikola for finding and fixing the issue.
Peace,
A. Jesse Jiryu Davis
mongo-c-driver 1.9.0
====================
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:
* mongoc_bulk_operation_execute did not always initialize "reply".
* Fix C99 pedantic warnings.

following bugs:
* Remove option to bundle the Snappy compression library, it caused issues
for programs linking to libmongoc
* Fix pkg-config and CMake config file flags for programs that statically
link to libmongoc when libmongoc is statically linked to zLib

mongo-c-driver 1.8.0
====================
* The zLib and Snappy compression libraries are bundled if not available.
Wire protocol compression is enabled on Windows.
* mongoc_collection_find_and_modify_with_opts now respects a "writeConcern"
field in the "extra" BSON document in its mongoc_find_and_modify_opts_t.
* The command functions mongoc_client_read_write_command_with_opts,
mongoc_database_read_write_command_with_opts, and
mongoc_collection_read_write_command_with_opts now ignore the "read_prefs"
parameter.
* mongoc_collection_create_index and mongoc_collection_create_index_with_opts
are both now deprecated. Use mongoc_database_write_command_with_opts
instead; a guide to creating an index using that function has been added.
* Use select, not WSAPoll, on Windows.
* Always mark a server "Unknown" after a network error (besides a timeout).
* mongoc_client_pool_t sends platform metadata to the server; before, only a
single mongoc_client_t did.
* New stream method mongoc_stream_timed_out.
* Wire version checks introduced in 1.8.0 will prevent the driver from
connecting to a future MongoDB server version if its wire protocol is
incompatible.
* New CMake option ENABLE_MAINTAINER_FLAGS.

mongo-c-driver 1.7.0
====================
It is my pleasure to announce mongo-c-driver 1.7.0.
New features and bug fixes:
* CMake build now installs .pc files for programs that link to libmongoc using
pkg-config. Both the CMake and Autotools build systems now install .cmake
files for programs that link to libmongoc using CMake. Linking to libmongoc
statically or dynamically is now much more convenient. See the new tutorial
section "Include and link libmongoc in your C program".
* New CMake option ENABLE_STATIC can be ON, OFF, or AUTO (the default)
* Minimum required CMake version has been increased to 3.1.
* CMake remains experimental on non-Windows platforms and issues a warning now
* Support for wire compression.
* Support for snappy and zlib. MongoDB 3.4 only supports snappy, while zlib
support is expected in MongoDB 3.6.
The enable, configure mongoc like so:
./configure --with-snappy --with-zlib
* New functions: mongoc_uri_get_compressors & mongoc_uri_set_compressors, to
get and set compressor configuration on mongoc_uri_t
* Added support for comma separated "compressors" connection string option (e.g.
mongodb://localhost/?compressors=snappy,zlib)
* Added support for configuring zlib compression level in the connection string
(e.g. mongodb://localhost/?compressors=zlib&zlibcompressionlevel=8)
* Now requires the use of CMake config files for libbson to build libmongoc
with CMake
* Added pkg-config support for libressl.
* New function mongoc_uri_set_auth_mechanism to update the authentication
mechanism of a mongoc_uri_t after it is created from a string.
* New function mongoc_bulk_operation_insert_with_opts provides immediate
error checking.
* New function mongoc_uri_new_with_error provides a way to parse a connection
string, and retrieve the failure reason, if any.
* Support for MongoDB Connection String specification
* All connection string options are now represented by MONGOC_URI_xxx macros
* Paths to Unix Domain Sockets must be url encoded
* Repeated options now issue warnings
* Special characters in username, password and other values must be url encoded
* Unsupported connection string options now issue warnings
* Boolean values can now be represented as true/yes/y/t/1 and false/no/n/f/0.
* Case is now preserved in Unix domain paths.
* New function mongoc_cursor_error_document provides access to server's error
reply if a query or command fails.
* New function mongoc_write_concern_is_default determines whether any write
concern options have been set, and mongoc_read_concern_is_default checks if
read concern options are set.
* mongoc_gridfs_find_one_with_opts optimized to use limit 1.

New features and bug fixes:
* Enterprise authentication on Windows now uses the native GSSAPI library;
Cyrus SASL is no longer required for enterprise auth on Windows.
* BSON documents are more thoroughly validated before insert or update.
* New function mongoc_uri_set_mechanism_properties to replace all the
authMechanismProperties on an existing URI.
* mongoc_uri_get_mechanism_properties asserts its inputs are not NULL.
* For consistency with other MongoDB drivers, mongoc_collection_save is
deprecated in favor of mongoc_collection_insert or mongoc_collection_update.
* The driver is now built and continuously tested with MinGW-W64 on Windows.
* Experimental support for HPUX.
* The correct operation ids are now passed to Command Monitoring callbacks.
* Fix a crash if the driver couldn't connect to the server to create an index.
* The documentation is ported from Mallard XML to ReStructured Text, the
HTML documentation is restyled, and numerous man page syntax errors fixed.
* Getter functions for options in mongoc_find_and_modify_opts_t:
* mongoc_find_and_modify_opts_get_bypass_document_validation
* mongoc_find_and_modify_opts_get_fields

====================
This release fixes a bug that prevented connecting to IPv4-only MongoDB servers
by hostname.
https://jira.mongodb.org/browse/CDRIVER-1988
The driver has reverted to its 1.5.1 behavior: it connects to MongoDB over IPv6
if given an IPv6 connection string like "mongodb://[::1]", and requires an IPv4
connection when given a hostname like "mongodb://localhost".

mongo-c-driver 1.5.0
====================
It is my pleasure to announce mongo-c-driver 1.5.0.
New features and bug fixes:
* MongoDB 3.4 Support
* New URI and read preference option, "maxStalenessSeconds"
* MongoDB Handshake
* writeConcern and readConcern enhancements
* Collation allows users to specify language-specific rules for string
comparison when sorting documents. See the code examples for
mongoc_client_read_command_with_opts, mongoc_collection_count_with_opts,
mongoc_collection_find_with_opts, and mongoc_index_opt_t, as well as the
"Setting Collation Order" section of the "Bulk Write Operations" guide.
* mongoc_collection_count_with_opts uses the collection's read preference if
none is passed in
* Improved TLS support
* Fixed LibreSSL (libssl) support
* Added LibreSSL (libtls) support
* Fixed Secure Channel build on VS 2010
* OpenSSL now supports SNI (all others already do)
* Additional features for Application Performance Monitoring:
* mongoc_topology_description_has_writable_server
* mongoc_topology_description_has_readable_server
* New functions accept flexible options as a BSON document:
* mongoc_collection_find_with_opts
* mongoc_client_read_command_with_opts
* mongoc_client_write_command_with_opts
* mongoc_client_read_write_command_with_opts
* mongoc_database_read_command_with_opts
* mongoc_database_write_command_with_opts
* mongoc_database_read_write_command_with_opts
* mongoc_collection_read_command_with_opts
* mongoc_collection_write_command_with_opts
* mongoc_collection_read_write_command_with_opts
* mongoc_gridfs_find_with_opts
* mongoc_gridfs_find_one_with_opts
* mongoc_collection_find is now deprecated in favor of
mongoc_collection_find_with_opts.
* New helper function to include read concern in one of the above function's
options parameter: mongoc_read_concern_append.
* mongoc_client_command no longer applies the client's read preference and
read concern by default. Same change for mongoc_database_command and
mongoc_collection_command.
* mongoc_collection_count_with_opts now applies the collection's read
preference if no read preference is provided
* mongoc_collection_create_index and mongoc_collection_drop_index now apply
the collection's write concern.
* connectTimeoutMS timer now begins after DNS resolution, and resets
for each interface attempted (e.g., if the driver first tries IPv6,
then IPv4).
* New error code MONGOC_ERROR_DUPLICATE_KEY.
* mongoc_collection_find no longer treats the "filter" key specially in
queries - querying for a document with a key named "filter" is the same
now as any other key.
* The server description parameter to the following functions is "const":
* mongoc_server_description_host
* mongoc_server_description_id
* mongoc_server_description_ismaster
* mongoc_server_description_round_trip_time
* mongoc_server_description_type
* Exported symbols are no longer declared in separate export files.
This could break ABI with applications using clang, which previously
exported symbols from the internal private ABI.
* mongoc no longer crashes when multi roundtrip bulk operation fails.
* Added support for the new readConcernLevel "linearizable".
* Clients now check for misformatted "readPreferenceTags" in URI.
* New CMake option ENABLE_TRACING allows debug output, which before had only
been available with "configure --enable-tracing".
* Bugfix: "PossiblePrimary"-type replicas could be selected for reads
* Bugfixes: The random number generator used to select servers is now properly
seeded, and secondary queries are now properly distributed according to
localThresholdMS, not just to the lowest-latency secondary.
* mongoc_collection_insert, mongoc_collection_update, mongoc_collection_remove
consistently use domain MONGOC_ERROR_BSON, code MONGOC_ERROR_BSON_INVALID
if passed oversized BSON, and MONGOC_ERROR_COLLECTION for other errors.
mongoc_bulk_operation_execute continues to use MONGOC_ERROR_COMMAND for
all errors.
* If mongoc_client_pool_t fails to start its scanner thread in the background,
it logs and aborts instead of silently continuing, then failing to connect.
* The driver now updates its view of the whole topology with information from
each new connection handshake.
* mongoc_client_set_apm_callbacks can be used repeatedly to change or clear
the list of monitoring callbacks.
* Improved error reporting when the driver fails to reach the server.
Deprecations:
* mongoc_collection_find is deprecated for mongoc_collection_find_with_opts.
Removed configure flags:
* --enable-experimental has been removed. All previously experimental
features are now always on.
* The configure option "--enable-hardening" had had no effect. It is removed
in favor of system-wide compiler configuration.

mongo-c-driver 1.4.0
====================
It is my pleasure to announce the release of mongo-c-driver 1.4.0.
TLS
---
The driver can now use the native TLS and crypto functions included in macOS
and Windows. OpenSSL is no longer required for TLS or authentication on Mac or
Windows. By default, OpenSSL is used if available, the default will switch in
version 2.0 to prefer native TLS.
For native TLS on Mac:
./configure --enable-ssl=darwin
For Windows:
cmake "-DENABLE_SSL=WINDOWS" -G "Visual Studio 10 Win64" "-DCMAKE_INSTALL_PREFIX=C:\mongo-c-driver"
All of the TLS implementations now load the native default certificate store,
with OpenSSL on Windows falling back on the Windows native certificate store if
no other can be found.
The "ca_dir" field on mongoc_ssl_opt_t is only supported by OpenSSL. All other
fields, including "pem_file", are supported by all implementations.
A new field, "allow_invalid_hostname", has been added to mongoc_ssl_opt_t and is
preferred over the existing "allow_invalid_certificate" to disable hostname
verification.
The driver now supports the latest OpenSSL 1.1 in addition to past versions.
Application Performance Monitoring
----------------------------------
The driver implements the MongoDB Command Monitoring Spec. Applications can
record the duration and other details of every operation the driver performs on
the server. See "Introduction to Application Performance Monitoring" in the
docs.
Error API
