 - The minimum version of Nix required to evaluate Nixpkgs has been raised from 2.3 to 2.18.
 
-- `buildPythonPackage` and `buildPythonApplication` now set `enabledTestPaths = [ "." ]` by default if not specified otherwise, and require the specified value to be a non-empty list to simplify overriding.
-
-  When running install-checks with `pytestCheckHook`, such default value resembles `pytest`'s default behaviour of discovering tests in the current working directory.
-
-  To support both version of Nixpkgs before and after this change, set `enabledTestPaths = [ "." ]` manually for packages that don't need custom `enabledTestPaths` specification.
-
 - The `offrss` package was removed due to lack of upstream maintenance since 2012. It's recommended for users to migrate to another RSS reader
 
 - `base16-builder` node package has been removed due to lack of upstream maintenance.
