We have released new features in the new Data model IDE. With the release of these features, the new Data model IDE will be the primary development environment from now on. We are focusing on merging our two development environments into one again. This step is part of this plan. In the new IDE we can offer a more seamless development environment with the Page Builder, which is highly important in our no-code and citizen development vision.

 

**What does this mean for me?**

- From now on, you can only mutate your data models and settings in the new IDE. When you click on the Data model icon in the builder bar (also from the old environment) you  always go to the new Data model IDE. Before, you had to switch between environments, because not all features were available in the new Data model IDE. Now, you can do (almost) everything in the new IDE, which makes your building experience more seamless, and saves you time. 
- Managing Application Roles is now part of the new IDE. Before, you could create and delete Application Roles in the Back office or via Actions, but now it is part of your Application description. This is platform architecturally a better design, and as a result you’ll experience a more stable environment. 

*Be aware: We will release this in batches for existing applications (starting today with the first batch). This means your existing application will have the new Data model IDE as a primary development environment within now and a few weeks.*

**What’s new?**

- Application Roles & Model permissions:
- Models and properties:
- Back door to old environment:
