May 1, 2026May 2026 focused on forward-compatibility for the Firebase Android SDK image model. In firebase/firebase-android-sdk, deprecated the TemplateImagen class and its methods, updated deprecation messaging, and provided a clear migration path to the Gemini image model. This work informs users about the discontinuation of Imagen models and guides migration to Gemini, laying groundwork for future releases and reducing deprecation-related support overhead. Implemented via a targeted commit to ensure minimal disruption while delivering long-term value.
