[keycloak-user] changes in Email SPI

Hi, In keycloak 1.4.0.Final I've made a custom EmailSender, plugging into the Email SPI. Now we're upgrading to 1.8.1.Final but I'm running into problems porting my existing EmailSender to 1.8.1. From the docs I understand that it has been split up. Has there been changes to the registration of the email SPI in keycloak-server.json? How do I register the emailtemplate and emailsender providers? Thank you Mark Hayen First8
