Your team is able to parallelize the Design and Verification of your program's different build gates in partitioned environments with side-by-side comparison views.

Quickly export a DOCX report of your System/Design Unit to share with suppliers and external parties.

Use this to create and share Filters of the person using Flow— you do not need to create one for each colleague.

Iterations

Documents and Requirements can now be linked across different projects. This can be used to reference analysis or reports done by different teams.

Text is now searchable within Text Custom Fields– both inclusions and exclusions.

Test Case steps and linked Requirements can be defined in the Test Case creation modal.

Cross-Project Document & Requirement Links

Verification Methods are now split into Automatic and Manual checks.

Use Automatic checks when you want your Verification to be driven from automated sources, such as Models, or Tests.

Manual checks allow you to get explicit sign-off from users from specific types of Verification.

You can now easily locate Systems in the side bar from within individual items. Simply hover over a System to access the button.

You can now configure which types of relationships cause items to be marked as Suspect.

Suspect triggers can be configured under 

Verification Methods 2.0

We've fully revamped our diagramming feature to be significantly more powerful and intuitive. You can easily arrange a variety of shapes and native Flow objects in a flexible and expressive way.

Diagrams are still a Beta feature - you can try them out under 

We're excited to release Document Sections. With these, your team can now write expressive, long form documents with your design deeply embedded. They're useful for communicating long-form findings that are relevant to your engineers, such as Analysis results.

You can now express equations natively in Flow using LateX syntax.

Diagrams 2.0

You can now create and share Views of your data.

Views cover both Filters and Columns, and can be either Public (shared within your Project), or Private (only accessible by you).

You can now see your Requirement Test Coverage and Parent-Child Breakdown within each System/Design Unit at a glance.

Click any part of the dashboard to switch to a filtered view of the relevant items.

You can now display Systems as Headings in Document View. Simply toggle the "Show System headers" setting on the Display button in the top-right.

Shareable Views

We’re thrilled to share that Flow has raised a $23M Series A led by Sequoia, with participation from Patrick & John Collison [Stripe]. We’re also welcoming Sequoia’s Managing Partner Roelof Botha to our board.

Thank you for trusting us to support your development. We couldn’t do this without you.

We’re all in on making Flow the backbone of your systems engineering process - faster, smarter, and more connected than ever. With this funding, we’re scaling our team, expanding product offerings and deepening our AI capabilities.

Flow Raises $23M Series A

You can now manage risks and failure modes directly in Flow, including DFMEAs, PFMEAs, and other structured risk analyses.

Settings > Project > Beta Features > Enable Risks View

' to get started. Make sure to link Risks to requirements to make it clear how each Risk impacts your design. 

The Interface table now supports multiple targets. To define the interface click on the Targets cell and tick the options you want. 

To trigger a change review when a custom field is changed go to 

Settings > Project > General > Custom Field Reviews

To import requirements in a ReqIF format go to 

Requirements > + New Requirement Dropdown > Import Requirements from ReqIF

In the design values table, type a unit (eg: kg, N, m/s) into the 'Find in View' search bar to quickly pull up all design values with that unit. 

The requirements document view now has a page style layout to make documents clearer.

You can also edit the requirement fields in the document view as you go through. Click the open details button for more information.

You can now see member email addresses in 

, making it easier to manage your organization.

Risks View

You can now comment, reply and resolve threads in Flow! 

To start a thread - go to an open change review and click the comment icon at the top.

To save time with approvals - admins and requirement owners can now bypass reviews by clicking the three dots.

There's a new filter that will show you open change reviews for any user. 

Combine with other filters to focus on the reviews you want. 

Just go to Add Filter > Awaiting Review > Select Users.

You can now give an interface a specific type - this will update the colour of arrows in Architecture view to make things easier to see.

The bulk edit menu is now easier to navigate - you’ll find options grouped under headings!

Test Cases can now have a type - which allows you to determine which custom fields show.

Test case stages and reviews coming soon!
