+v2.15.9rc1
+==========
+
+Release Summary
+---------------
+
+| Release Date: 2024-01-22
+| `Porting Guide <https://docs.ansible.com/ansible-core/2.15/porting_guides/porting_guide_core_2.15.html>`__
+
+
+Minor Changes
+-------------
+
+- ansible-test - Removed `freebsd/12.4` remote.
+
+Security Fixes
+--------------
+
+- ANSIBLE_NO_LOG - Address issue where ANSIBLE_NO_LOG was ignored (CVE-2024-0690)
+
+Bugfixes
+--------
+
+- ``ansible-galaxy role import`` - fix using the ``role_name`` in a standalone role's ``galaxy_info`` metadata by disabling automatic removal of the ``ansible-role-`` prefix. This matches the behavior of the Galaxy UI which also no longer implicitly removes the ``ansible-role-`` prefix. Use the ``--role-name`` option or add a ``role_name`` to the ``galaxy_info`` dictionary in the role's ``meta/main.yml`` to use an alternate role name.
+- ``ansible-test sanity --test runtime-metadata`` - add ``action_plugin`` as a valid field for modules in the schema (https://github.com/ansible/ansible/pull/82562).
+- ansible-config init will now dedupe ini entries from plugins.
+- ansible-galaxy role install - normalize tarfile paths and symlinks using ``ansible.utils.path.unfrackpath`` and consider them valid as long as the realpath is in the tarfile's role directory (https://github.com/ansible/ansible/issues/81965).
+- delegate_to when set to an empty or undefined variable will now give a proper error.
+- unsafe data - Enable directly using ``AnsibleUnsafeText`` with Python ``pathlib`` (https://github.com/ansible/ansible/issues/82414)
