In App Engine Flexible, how do I use a Go version beyond 1.15?

[Gabor Lenard]

Hello everyone

I would like to use the latest available Go version in Google App Engine Flexible. However, the latest supported Go version seems to be 1.15, see https://cloud.google.com/appengine/docs/flexible/go/runtime The responsible repository was not updated since 2020, and relevant pull requests are ignored for unknown reasons, see https://github.com/GoogleCloudPlatform/golang-docker 

I know it’s not fully relevant in this group but who else could help?

Best,

Gabor
