--- description: Available in Phoenix 12.0+ --- # 09.26.2025: Session Annotations🗂️ {% embed url="https://storage.googleapis.com/arize-phoenix-assets/assets/images/session-annotation.png" %} With this change, annotation columns are added directly to the sessions table, making it possible to see session-level annotations in list views. Users no longer need to drill down into individual sessions to spot annotations. This gives better visibility and quicker context when browsing sessions in bulk. {% embed url="https://arize-phoenix.readthedocs.io/projects/client/en/latest/api/sessions.html" %}
