Google Cloud Endpoints Frameworks v2 replaces v1. Migration to v2 encouraged now, required as of August 2, 2018.
Google Cloud Endpoints Frameworks v1 is deprecated as of August 2, 2017. Users of v1 are encouraged to migrate to Cloud Endpoints Frameworks v2 at their earliest convenience. The v1 Endpoints Frameworks will cease to serve traffic on August 2, 2018.
Google Cloud Endpoints Frameworks v2 (in both Java and Python) have been generally available since February 2017. They have a streamlined serving path and include several improvements over v1:
- they reduce warmup time,
- they reduce latency per-call, and
- they have a much better local debugging experience.
They also support custom paths and custom domain names, and they optionally allow API management features such as monitoring and API keys. The new versions are also open sourced (Java, Python).
