3 Commits • 1 Features
Feb 1, 2026February 2026: Strengthened CI/CD and rendering reliability for Mermaid (mermaid-js/mermaid). Key updates delivered include upgrading the Cypress browser image in CI and cleaning up outdated changeset references to reflect the upgrade, as well as fixing Flowchart Labels Rendering to ensure non-markdown labels render correctly without wrapping. These changes reduce flaky tests, improve feedback loops, and enhance flowchart authoring for users.

Jan 1, 2026January 2026 monthly summary for mermaid-js/mermaid. This period focused on rendering fidelity, diagram stability, and maintainability. Key accomplishments include delivering the Label Rendering Enhancements and CreateLabel API (refactoring for type safety, consolidated helpers, improved image handling), restoring ER Box rendering stability, fixing edge label rendering when htmlLabels is false, advancing parser and architecture diagram support (multiline accDescr, quotes in labels, robust architecture title parsing), introducing a global HTML labels configuration (deprecating per-diagram flowchart.htmlLabels), and completing code quality and lint fixes. These changes provide tangible business value by reducing rendering regressions, improving user experience, and enabling faster feature delivery with lower maintenance costs.
