Any impact on twilio-go, terraform-provider-twilio, or twilio-cli?

[charan678]

Yes, There is impact on Golang. Enum names will be changed in golang. We will fix it tomorrow and will not merge YPS changes until we verify golang and terraform changes. Will raise golang and terraform changes tomorrow for review.
