Publishing pre-release versions of Provider ("Ignored draft release event")

Was there a recent change in how terraform registry deals with pre-releases (i.e. beta/rc)? I am trying to publish Release v2.1.0-beta1 · alekc/terraform-provider-kubectl · GitHub but webhook returns “Ignored draft release event” (even if github release is switched from pre-release to release state)? It was not a case earlier (<6m ago).
