+**************
+
+Version 0.37.0
+==============
+
+**Release Date:** September 27, 2024
+
+**Breaking Changes**
+
+-  API: Remove the ``model_hub`` library from Determined.
+
+-  Starting with this release, ``MMDetTrial`` and ``BaseTransformerTrial`` are removed. HuggingFace
+   users should refer to the provided `HuggingFace TrainerAPI examples
+   </~https://github.com/determined-ai/determined/tree/main/examples/hf_trainer_api>`__, which use a
+   custom callback instead of BaseTransformerTrial. Users of ``MMDetTrial`` can refer to :ref:`Core
+   API <api-core-ug>`.
+
+**New Features**
+
+-  Webhooks: Add support for experiment monitoring and alerting. Capabilities include
+   workspace-level subscriptions for "All experiments" or "Specific experiment(s) with matching
+   configuration" options. New trigger types include ``COMPLETED``, ``ERROR``, ``TASKLOG``, and
+   ``CUSTOM``. Support for custom triggers, code-based alerts, experiment-specific webhook
+   exclusions, and editable webhook URLs is also added. For details, visit
+   :ref:`supported-webhook-triggers`.
+
+-  Master Configuration: Add support for POSIX claims in the master configuration. It now accepts
+   ``agent_uid_attribute_name``, ``agent_gid_attribute_name``, ``agent_user_name_attribute_name``,
+   or ``agent_group_name_attribute_name``. Refer to the :ref:`OIDC master configuration
+   <master-config-oidc>` or :ref:`SAML master configuration <master-config-saml>` for details. If
+   any of these fields are configured, they will sync with the database.
+
+**Improvements**
+
+-  WebUI: Change the "Compute Slots Allocated" label to "Unspecified Slots Allocated" for resource
+   pools with no or multiple slot types. Add error logs for zero or multi-slot-type cases and update
+   the progress bar to include all agents when the slot type is ``TYPE_UNSPECIFIED``.
+
+**Bug Fixes**
+
+-  API/Tasks: Fix a bug where a master-configured ``log_retention_days`` value is not applied to
+   experiments and tasks. The master-configured value is now correctly applied to new experiments,
+   and all pre-existing experiments will also follow the specified ``log_retention_days``.
