I recived email from firebase look like :

Starting September 1, 2024, future versions of the gcloud functions deploy CLI command will create Cloud Functions using 2nd generation by default. If you do not wish to create a 2nd generation function, you can override this behavior by using the --no-gen2 CLI flag.

Additionally, the firebase-functions Node.js SDK will begin defaulting to the v2 API instead of the v1 API. The v2 API is available now at firebase-functions/v2.

Cloud Functions for Firebase has two product versions:

Cloud Functions (1st generation), the original version, used whenever targeting the firebase-functions/v1 SDK.
Cloud Functions (2nd generation), a new version built on Cloud Run and Eventarc providing an enhanced feature set, which has been generally available since 2022.
This is used whenever you need to target the firebase-functions/v2 SDK.

But in email i don’t find any information after. 1 Steptember 2024 i can use cloud function or firebase function if not update to gen2. Is possible if i not updated and not fix code from require(‘firebase-functions); to require(‘firebase-functions/v1’) and my code running normally after 1 Steptember 2024? If i keep require(‘firebase-functions’); and keep logic deploy is : gcloud functions deploy or firebase deploy –only function it will still function normally after. 1 Steptember 2024 ? Thanks you
