​@Barramundi I’m not quite sure what you mean by “roadmap” or what the question is specifically. However, I have found two links that appear to be related. Perhaps these will help you:

Hi ​@Barramundi , 

Thanks for posting in the Lucid Community! 

Sequence diagrams are based on time and show the order of events. Each arrow represents an action, and the arrows must follow a clear direction to show the sequence of events. Because of this, bidirectional arrows aren’t typically supported in a sequence diagram. If you need to show a bidirectional flow, you would use two arrows: one going in each direction, placed on separate lines.

However, you can use bidirectional arrows in a flowchart diagram, as they are not time-based like sequence diagrams.

As for the other types of arrows you mentioned, those are supported in sequence diagrams—the only ones not supported are bidirectional arrows

Please let me know if you have any additional questions! 

Just to clarify that I’m talking about the beta diagram as code support for generating diagram with mermaid syntax in Lucid and It’s not the UML sequence code. The mermaid syntax supports bidirectional and other arrows in later versions, https://mermaid.js.org/syntax/sequenceDiagram.html#aliases. Just asking if Lucid have the product roadmap to support this mermaid version v11 above

Hi ​@Barramundi,

Thanks for providing the additional information! Lucidchart currently supports Mermaid version 10.2.3. To learn more about Mermaid in Lucidchart, check out our Diagram as code with Mermaid in Lucidchart article. To see example syntax for supported diagrams, check out this Community post. 

Thank you!
