27.0.0 (2026-10-19)
⚠ BREAKING CHANGES
- ios: drop CocoaPods Firebase matrix; SPM-only
- app, sdk: bump Firebase Android 35, Apple 13, and JS 13
- ml: remove discontinued @react-native-firebase/ml package
- app, ios: RNFBSharedUtils.h, RCTConvert+FIRApp.h, and
RCTConvert+FIROptions.h no longer import FirebaseCore; RNFBUtilsModule.h
no longer imports Photos. Add the import at the call site if you need
those types. See docs/migrating-to-v27.mdx. - app, ios: initializeApp now reads automaticDataCollectionEnabled as a
boolean. Previously any non-nil value (including JS false) enabled collection
via pointer cast; false, 0, null, and absent now disable it. See
docs/migrating-to-v27.mdx. - ai: The Imagen API is removed from @react-native-firebase/ai.
getImagenModel(), getTemplateImagenModel(), ImagenImageFormat, and the Imagen
request and response types are gone. Generate images with Gemini image models
through getGenerativeModel() instead, setting responseModalities and
imageConfig on the generation config. See docs/migrating-to-v27.mdx for the
full mapping of removed exports and before/after code.
