We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.
- Tooltips for emoji in Diagram Syntax doc tree: This issue proposes adding tooltips to the emoji displayed next to the names of various diagram types in the "Diagram Syntax" section of the documentation tree. The goal is to help users understand the meaning of these icons, as currently there is no reference explaining their significance, which can lead to confusion even for experienced users.
- log scale for
xychart-beta: This issue proposes adding ascalestring field to thexychart-betacomponent that defaults tolinearbut can also acceptlogas an option, enabling the plotting of logarithmic scales while maintaining version control of the original non-logged data. The enhancement aims to support future extensions to other scale types and includes an example demonstrating how to specify a log scale for chart axes in the graph description. - SVG rendering formatting issues with markdown input: This issue addresses problems with SVG rendering when nodes in a diagram use markdown formatting, resulting in inconsistent visual output such as added height or text being cut off in the SVG files. Specifically, these formatting issues occur when opening the SVG in a new tab or downloading it from the editor, causing discrepancies between the expected and actual appearance of the diagram nodes.
- Vite build error with mermaid version 10.9.0: This issue describes a build error encountered when using Mermaid version 10.9.0 in a Vue 3 and Vite application. While the Mermaid graphs render correctly during development, the application fails to start after building, producing a "TypeError: Cannot set properties of undefined (setting 'prototype')" related to Mermaid's internal code. Since there were fewer than 5 open issues, all of the open issues have been listed above.
2.3 Open Issues
This section lists, groups, and then summarizes issues that were created within the last week in the repository.
Issues Opened This Week: 3
Summarized Issues:
- Workflow and Support System Design: This topic covers the proposal of a detailed workflow diagram for a Rider App support system, describing the process from rider concern submission to ticket management and partner portal handling. The workflow includes time-based turnaround times and communication updates, aiming to streamline support operations efficiently.
- issues/6805
- Diagram Type Support and Proposal: This topic involves the proposal to add use case diagram support to the project, referencing a detailed proposal document. However, the issue currently lacks concrete use cases, screenshots, syntax details, and implementation plans, indicating it is still in an early stage.
- issues/6806
- Flowchart Click Event Bug: This topic addresses a bug in Mermaid flowcharts where click event callbacks fail silently if the
securityLevelis not set to"loose". This silent failure complicates debugging as no warnings or errors are provided when the callbacks do not fire. - issues/6809
2.4 Closed Issues
This section lists, groups, and then summarizes issues that were closed within the last week in the repository. This section also links the associated pull requests if applicable.
Issues Closed This Week: 2
Summarized Issues:
- Architecture Diagram Updates: This topic covers the need to update the architecture diagram to reflect the new class-based approach used in the database. The issue highlights changes in design representation that must be accurately depicted in the diagram.
- issues/6774
- Syntax Errors in Flowchart Rendering: This topic involves syntax errors caused by including the character sequence 'graph' in node text when using the 'elk' flowchart renderer. The problem particularly affects rendering multiple diagram types on a single page, leading to parser failures.
- issues/6795

- URL: pull/6796
- Merged: 2025-07-30T09:52:26Z
3. Fix: zenuml rendering: This pull request fixes a rendering issue in ZenUML diagrams by upgrading the @zenuml/core dependency to version 3.35.2, addressing a timing problem that caused diagrams to be copied before rendering completed, and includes updates such as converting the ZenUML README from a symlink to a standalone file, removing TypeScript error suppressions, adding TypeScript declarations, and ensuring proper documentation and testing.
- URL: pull/6798
- Merged: 2025-07-29T09:54:15Z
Other Closed Pull Requests
- Refactoring database implementations: Multiple pull requests refactor diagram database implementations from function-based modules to class-based designs, introducing new classes like
ArchitectureDBandPacketDB. These changes improve modularity, testability, and maintainability while preserving backward compatibility and preparing the modules for future enhancements. - [pull/6803, pull/6804]
- Fixing and updating workflow messages: One pull request focuses on fixing and updating workflow messages in the Mermaid project, refining the content through multiple commits to improve clarity and correctness.
- [pull/6808]
- Consistency fixes in diagrams: Pull requests address consistency issues such as fixing the casing of "id" to "ID" in requirement diagrams and trimming leading spaces in flowchart direction strings to ensure correct interpretation. These fixes align the diagrams with standards and improve parsing accuracy.
