### Improvements and changes

- We revamped the toolbar in our scenario editor! We have made numerous visual and functionality improvements, like moving the **Run once **button into the toolbar or making the toolbar expandable. Read more about the new toolbar [here](https://www.make.com/en/help/scenarios/scenario-editor).

- The [subscenarios](https://www.make.com/en/help/scenarios/subscenarios) have officially exited closed beta and are now available to all users in **Teams and Enterprise **organizations.
- The custom IML function for developing custom apps has been re-enabled! It was disabled because of security reasons, and is now available again.
- We are migrating the existing custom apps to the new technology in batches, so it might take time until you can edit a custom IML function in an already existing custom app. You can read more about the re-enablement [here](https://developers.make.com/custom-apps-documentation/app-structure/custom-iml-functions/re-enablement-of-the-custom-iml-functions-in-make).
