+## 0.26.0 (January 22, 2025)
+
+BREAKING CHANGES:
+
+* tfprotov5+tfprotov6: `EphemeralResourceServer` interface is now required in `ProviderServer`. Implementations not needing ephemeral resource support can return errors from the `*EphemeralResource` methods. ([#442](https://github.com/hashicorp/terraform-plugin-go/issues/442))
+* tfprotov5+tfprotov6: Removed temporary `ProviderServerWithEphemeralResources` interface type. Use `EphemeralResourceServer` instead. ([#442](https://github.com/hashicorp/terraform-plugin-go/issues/442))
+
+NOTES:
+
+* all: To prevent compilation errors, ensure your Go module is updated to at least [email protected], [email protected], terraform-plugin-sdk/[email protected], and [email protected] before upgrading this dependency. ([#442](https://github.com/hashicorp/terraform-plugin-go/issues/442))
+
+FEATURES:
+
+* tfprotov5+tfprotov6: Upgraded protocols and added types to support write-only attributes ([#462](https://github.com/hashicorp/terraform-plugin-go/issues/462))
