@ -12,6 +12,7 @@ BUG FIXES:
* Fix inmem backend crash due to missing struct field ([#1619](https://github.com/opentofu/opentofu/pull/1619))
* Added a check in the `tofu test` to validate that the names of test run blocks do not contain spaces. ([#1489](https://github.com/opentofu/opentofu/pull/1489))
* `tofu test` now supports accessing module outputs when the module has no resources. ([#1409](https://github.com/opentofu/opentofu/pull/1409))
* Fixed support for provider functions in tests ([#1603](https://github.com/opentofu/opentofu/pull/1603))
