+* Version `v3.1.*` supports both Terraform `0.14` and `0.15.0`. However, it throws warnings regarding empty providers deprecation. Provider configuration was changed in Terraform `0.15.0`. Therefore, newer versions would likely be incompatible with Terraform `<=0.15`. So, if you need to use both Terraofmr `0.14` and `0.15` at the same time or you're in the process of migration, please, use `v3.1.*` of this module.
