Hello,

This repository contains sprites generated from logos at Gilbarbara's logos repo. If you ask there for the logo inclusion, we can then easily re generate plant uml sprites including the new logo.

Regards.

Thank you, I'll check with them now.

[Updated]:
I already opened the issue, waiting for them to confirm.
