PHP 7, REST by default, gRPC
New in Version 5.0
As of version 5 (May 2021), this library provides support for
- PHP 7 second-generation App Engine runtimes - using the REST API by default
- PHP 7 "anywhere" (e.g. Google Compute Engine, Cloud Run, GKE) - using REST or gRPC
Key features removed from version 5 onwards
- PHP 5 support
- Support for the legacy "Protocol Buffer" API built into first-generation App Engine runtimes
If you need to continue running applications on that infrastructure, stick to version 4.x or earlier.
