The introduction of Flows allows you to define multiple workflows to accommodate your lines of business. Each of these workflows can be customized. ** Upon upgrading to v30, you will have a standard flow used to process all of your submissions. ** If you would like to make changes to this flow, contact your Hyperscience representative for assistance. #### _Settings in v30_ Due to the modular nature of flows, many settings that previously applied to an instance as a whole are now specific to individual blocks. #### _Limitations in v30_ Key limitations include: - You will need to reach out to your Hyperscience representative if you would like to add new flows or make changes to your current ones. - These settings and configurations will continue to apply to all of your flows, with flow-specific customizations expected in future releases. This concludes the cleaned version of the release notes.
