| enable_language-subdirectory | |
| ---------------------------- | |
| * The :command:`enable_language` command, and the :command:`project` command | |
| that calls it, may now be used in a subdirectory to enable a language for | |
| targets in ancestor directory scopes. The language configuration is | |
| propagated up to enclosing scopes. This also lifts the restriction for | |
| calling inside of :command:`block` and :command:`function` commands. See | |
| policy :policy:`CMP0220`. |
