I'm creating a new scratch org - will it be based on Summer '19 (production org edition) or Spring '19 (sandbox edition)?

Question

I can't find the answer to this anywhere quickly - what controls the edition? Production is on Summer '19 while all previous scratch orgs are on the Spring '19. If I create a new scratch org now after the GA release , will that scratch org have Summer '19 functions?

Edit: tested this. It's summer '19. So there you have it.

Answer 1

Once your production org is on summer 19 and if it has the devhub enabled all the new scratch orgs will be on summer 19 only .

Note that from next release (when winter 20) devhub will allow to create orgs in Salesforce pre release version as well .
