| ------------------------------------- |
| |
| * The :ref:`Ninja Generators` gained the |
| :prop_tgt:`Swift_SEPARATE_MODULE_EMISSION` target property, initialized by |
| the :variable:`CMAKE_Swift_SEPARATE_MODULE_EMISSION` variable, to control |
| whether importable Swift targets emit ``.swiftmodule`` from a dedicated |
| build edge. Policy :policy:`CMP0215` enables this by default. |
| |
| * The default :prop_tgt:`Swift_MODULE_NAME` now replaces hyphens with |
| underscores, since hyphens are not valid in Swift module identifiers. |
