+NOTES:
+
+* all: This Go module has been updated to Go 1.24 per the [Go support policy](https://go.dev/doc/devel/release#policy). It is recommended to review the [Go 1.24 release notes](https://go.dev/doc/go1.24) before upgrading. Any consumers building on earlier Go versions may experience errors. ([#556](https://github.com/hashicorp/terraform-plugin-go/issues/556))
+* tfprotov5+tfprotov6: An upcoming release will require the `ActionServer` implementation as part of `ProviderServer`. ([#534](https://github.com/hashicorp/terraform-plugin-go/issues/534))
+
+FEATURES:
+
+* tfprotov5+tfprotov6: Upgraded protocols and added types to support the new action type. ([#534](https://github.com/hashicorp/terraform-plugin-go/issues/534))
+* tfprotov5+tfprotov6: Upgraded protocols and added types to support the new list type ([#525](https://github.com/hashicorp/terraform-plugin-go/issues/525))
+
+ENHANCEMENTS:
