 * Skip imports blocks logic on `tofu destroy` ([#2214](https://github.com/opentofu/opentofu/pull/2214))
 * Updated github.com/golang-jwt/jwt/v4 from 4.4.2 to 4.5.1 to make security scanners happy (no vulnerability, see [#2179](https://github.com/opentofu/opentofu/pull/2179))
 * `tofu test` is now setting `null`s for dynamic type when generating mock values. ([#2245](https://github.com/opentofu/opentofu/pull/2245))
+* Variables declared in test files are now taking into account type default values. ([#2244](https://github.com/opentofu/opentofu/pull/2244))
