Firebase

Recently shipped DML support for the Firestore emulator and CLI flows that run unattended for AI agents.

Firestore emulator gained DML support — v15.25.0 bumped the emulator to v1.22.0 with Data Manipulation Language. It also fixed Storage emulator hangs on JSON uploads over 100KB and under concurrent requests.

The CLI now adapts to AI agents — v15.26.0 auto-enables non-interactive mode when an AI agent is detected in the environment, preventing hangs on interactive prompts. New two-phase login: firebase login --non-interactive prints a link, then firebase login <auth_code> completes it. v15.25.1 fixed a secret-param typo and handles service account propagation delays during Cloud Functions deploys.

New debug and Crashlytics commands — appcheck:debugtokens:create/list/delete manage App Check debug tokens from the terminal. crashlytics:onboard:web adds web onboarding, and source map uploads now accept hidden maps.

JS SDK added text-to-speech — @firebase/ai 2.14.0 supports TTS for non-Live models like Gemini TTS, single- or multi-speaker. VertexAIBackend is deprecated in favor of AgentPlatformBackend to match the Vertex AI → Gemini Enterprise Agent Platform rename.

Experimental standalone CLI binaries — Node 26 single-executable-application previews (v15.26.0-sea.preview.1/2) ship as Universal 2 macOS binaries with automated Mach-O ad-hoc code signing.

Still active from earlier releases — 2nd gen Cloud Functions declarative security and automated IAM, SQL Connect's 1:1 nested mutations, Auth emulator mock passkeys, and App Check auto-init on JS.
