Microsoft published the spring '18 release notes for Dynamics365. Go here to see them. These release notes also include a lot of new features for Microsoft Flow.
I would like to highlight some of them in this blog post:
Request for sign-off flow built into SharePoint
With this feature, you will be able to use a standard out of the box Flow to request sign-off from a person in your organization. For me, this out of the box Flow is another (good) attempt of Flow to improve their approval story. It will automatically create a text column where SharePoint will show the sign-off status.
Customize SharePoint content approvals with Flow
I love this one! The addition of SharePoint content approvals in Flow is one of the most heard requests from clients. It's a great addition to what they have today, and it shows Flow is a worthy successor of SharePoint designer.
Flows “owned by” SharePoint lists and libraries
Microsoft positioned Flow as a personal productivity tool. More and more, I see Flow moving into the team-space. Before, there were team flows, but this is another team-feature. The big benefit of this feature is that users in your lists and libraries will automatically have permissions for the Flows attached to that list or library. No need to give them permissions in Flow too.
I think the way of configuring this is straightforward and I already see tons of scenarios for this feature.
Test your flow by using sample data
This feature makes it easier to test your Flow before putting it out "in the wild". You can check if your Flow runs with test data or previous data and fix errors without having to leave the Flow website.
Build and run flows from Excel
One of my personal favorites. The Flow Excel add-in will help users to do data entry into a lot of different systems. At a lot of clients, I still see many excel sheets lingering around, and this would help almost every single one of my clients to adopt Flow widely.
Note: this will only be available for files that live in the cloud (SharePoint Online or OneDrive).
Return data to PowerApps from a flow
I can't believe this isn't there yet. This feature is a big deal! I can't wait to play around with this.
Automate governance with PowerShell
Save the best for last! Everyone who works with Flow a lot loves automation. No surprise here when the Flow & PowerApps teams announced PowerShell admin cmdlets. These cmdlets make it easier for admins to control their environments.
The Microsoft Flow team is on a roll, and I can't wait for the next big update! Make sure to send your feedback to the Microsoft Flow team and comment on their blog post about these updates!
