 ### Changed
 
 - **Breaking change** Removed `workstation_cidr` variable, http callout and unnecessary security rule. (by @dpiddockcmp)
+  If you are upgrading from 1.4 you should fix state after upgrade: `terraform state rm module.eks.data.http.workstation_external_ip`
 - Can now selectively override keys in `workers_group_defaults` variable rather than callers maintaining a duplicate of the whole map. (by @dpiddockcmp)
