Version information
Version 2.13.0•for Jira Cloud
- Release date
- Nov 4th 2026
- Summary
- Rovo AI agent for Mermaid diagrams — chat to create, read and update
- Details
Mermaid Plus Diagrams for Jira now ships with a Rovo AI agent. Ask in plain language and it attaches a Mermaid diagram to any issue, reads a diagram's source back, and updates diagrams in place — your theme and color settings are always preserved.
The agent understands all 30 Mermaid v12 diagram types, including ZenUML sequence diagrams, and works right from the issue view. The same create, read and update tools are also exposed as MCP tools, so Rovo Studio agents and third-party MCP clients can manage issue diagrams programmatically.
Diagrams stay stored on the issue where the panel has always kept them — the agent writes the same store your team edits by hand, so every change appears in the panel instantly.
Also in this release: the app is now named "Mermaid Plus Diagrams & AI Agent for Jira". Everything else is unchanged — same panel, same editor, same pricing.
For teams documenting designs and workflows on issues — diagrams both people and AI can edit.
