Describe your environment

• Operating System version: Ubuntu 22.04.4 LTS
• Firebase SDK version: v12.1.1
• Firebase Product: messaging
• Node.js version: v20.12.2
• NPM version: 10.5.0

Describe the problem

According to FAQ for FCM features deprecated in June 2023, the API endpoint https://fcm.googleapis.com/fcm/send is shutting down and:

Requests to the endpoint will start failing after 6/21/2024.

It has been replaced by HTTP v1 endpoint: https://fcm.googleapis.com/v1/projects/myproject-b5ae1/messages:send

However, in this latest v12.1.1 version of firebase-admin-node, there are 4 methods still using this legacy endpoint:

• sendToDevice
• sendToDeviceGroup
• sendToTopic
• sendToCondition

Only methods sendToDevice and sendToDeviceGroup are marked as deprecated, but methods sendToTopic and sendToCondition are not - despite all of them using the same endpoint. But won't all four of them stop working soon? So shouldn't they have been already removed in the latest version? It is a breaking change.
