 What's New in 1.18
 ------------------
 
 - Adds a new GridFS API to make it more convenient to work with files using PHP's 
-  existing filesystem functions. The :ref:`MongoDB\GridFS\Bucket::registerGlobalStreamWrapperAlias() <gridfs-bucket-register-global>` 
-  method may be used to register a global alias for a GridFS bucket. After doing so, files within that bucket 
-  can be accessed using only a file URI (e.g. "gridfs://mybucket/hello.txt"). A demonstration of this 
-  API can be found in the `gridfs_stream_wrapper.php <https://github.com/mongodb/mongo-php-library/blob/1.18.0/examples/gridfs_stream_wrapper.php>`_

   example script.
 
+- The ``MongoDB\Client`` class now has :ref:`addSubscriber() <api-client-add-subscriber>` 
+  and :ref:`removeSubscriber()<api-client-remove-subscriber>` methods to make it 
+  easier to register monitoring classes on the underlying ``MongoDB\Driver\Manager``
+  object.
+
+To learn more about this release, see the `v1.18 Release Notes

+
+.. _php-lib-version-1.17:
+
+What's New in 1.17
+------------------
+
+- Introduces a new "codec" API for converting BSON to and from PHP objects. 
+  More information on this feature may be found in the 
+  :ref:`Codecs tutorial <php-codecs>`.
+
+- Adds :ref:`MongoDB\add_logger() <api-add-logger>` and 
+  :ref:`MongoDB\remove_logger() <api-remove-logger>` functions to the library. 
+  These functions allow applications to register a `PSR-3 Logger <https://www.php-fig.org/psr/psr-3/>`__
+  to receive log messages emitted by the driver. Previously, logs were only 
+  accessible via the extension's `mongodb.debug <https://www.php.net/manual/en/mongodb.configuration.php#ini.mongodb.debug>`__ 
+  INI setting.
+
+- Introduces new :ref:`MongoDB\Collection <api-mongodb-collection-class>` methods 
+  to create and manage :atlas:`Atlas Search indexes </atlas-search>`. Atlas 
+  Search indexes can be queried using the :manual:`$search </reference/operator/aggregation/search/>` 
+  aggregation pipeline stage, which is supported in all versions of the library.
+
+- Upgrades the ``mongodb`` extension requirement to 1.17.0. Support for PHP 
+  7.2 and 7.3 has been removed and the library now requires PHP 7.4 or newer.
+
+To learn more about this release, see the `v1.17 Release Notes 
+<https://github.com/mongodb/mongo-php-library/releases/tag/1.17.0>`__ on GitHub.
+
+.. _php-lib-version-1.16:
+
+What's New in 1.16
+------------------
+
+- Introduces support for :v7.0:`MongoDB 7.0 </release-notes/7.0>`. 
+
+- Introduces :ref:`MongoDB\Database::createEncryptedCollection() <api-database-create-encrypted>`. 
+  This method automatically creates data encryption keys when creating a new 
+  encrypted collection.
+
+- This release upgrades the ``mongodb`` extension requirement to 1.16.0.
+
+To learn more about this release, see the `v1.16 Release Notes 
+<https://github.com/mongodb/mongo-php-library/releases/tag/1.16.0>`__ on GitHub.
+
+.. _php-lib-version-1.15:
+
+What's New in 1.15
+------------------
+
+- Adds new ``examples/`` and ``tools/`` directories to library repository, 
+  which contain code snippets and scripts that may prove useful when writing 
+  or debugging applications, respectively. These directories are intended to 
+  supplement the library's existing documentation, and will be added to over time.
+
+- Various backwards compatible typing improvements have been made throughout the
+  library. Downstream impact for these changes are discussed in 
+  `UPGRADE-1.15.md <https://github.com/mongodb/mongo-php-library/blob/1.15.0/UPGRADE-1.15.md>`__. 
+  
+- Integrates `Psalm <https://psalm.dev/>`__ for static analysis.
+
+- This release upgrades the ``mongodb`` extension requirement to 1.15.0.
