## Managing Conditionality in Subcomponents

In release 94, we released a new feature to allow you to manage when your subcomponents should appear, based on certain conditions.

You can read more about that [here](/components/component-library/modular-checkout-components/managing-conditionality-in-subcomponents.md).

## Custom subcomponents

From release 102, for customers using the Limio Developer Experience to create custom components, it is now possible to create custom subcomponents.

This enables new workflows and means even more customisation is possible when developing a checkout flow. Whether it's inserting custom fields to collect user information or displaying information, it is now possible to deliver that easily with just one small change.

To read more about custom subcomponents, you can visit our [docs here](https://docs.limio.com/developers/custom-components/custom-subcomponents).
