+    (https://github.com/ansible-community/antsibull-core/pull/132)."
+removed_features:
+  - "``ansible_core`` - remove ``get_ansible_core_package_name()`` function.
+    This is no longer necessary now that support for ansible-base has been dropped
+    (https://github.com/ansible-community/antsibull-core/pull/132)."
+  - "``ansible_core`` - remove ansible-core/ansible-base normalization in
+    ``AnsibleCorePyPiClient``. Data retrieval is only supported for ``ansible-core``
+    (https://github.com/ansible-community/antsibull-core/pull/132)."
+  - "``dependency_files`` - drop support for ``_ansible_base_version`` and
+    ``_acd_version`` in pieces files. ``_ansible_core_version`` and
+    ``_ansible_version``, respectively, should be used instead
+    (https://github.com/ansible-community/antsibull-core/pull/132)."
