Release notes

Sourced from mermaid's releases.

mermaid@11.16.1

Patch Changes

• #8022 12d472c Thanks @​aloisklink! - fix: handle CSS sibling combinators in compileCSS

• #8022 2cd6dcf Thanks @​aloisklink! - fix: increase protections against prototype pollution

  User-controlled input already has protections against prototype pollution.

  Fixes: GHSA-c4c3-pg64-4m4v

• #8022 99af3fc Thanks @​aloisklink! - fix(architecture): use Maps and Sets to store groups/services

  Services are now rendered in the order they are defined and more service IDs are now supported.

• #8022 2cd6dcf Thanks @​aloisklink! - deprecate: Deprecate the mermaidAPI.setConfig() function

  Calling this function has no observable effect, as the next time a render() or parse() is called, the currentConfig is cleared.

• #8022 630aa7e Thanks @​aloisklink! - fix(xychart): support zero-width x-axis ranges

• #8022 59b22fa Thanks @​aloisklink! - fix(radar): limit number of ticks to 32

  Setting a ticks value higher than this would only show 32 ticks.

mermaid@11.16.0

Minor Changes

• #7535 ea1c48f Thanks @​ragelink! - feat(cynefin): Adds the Cynefin framework as a new diagram type (beta) to Mermaid (available as cynefin-beta). The Cynefin framework, created by Dave Snowden, is a decision-making framework that categorizes problems into five complexity domains, widely used in agile, incident management, strategy, and organizational design.

• #7721 f45cc2c Thanks @​notionparallax! - feat(treeView): add box-drawing character input support for treeView diagrams

• #7550 f1f4d45 Thanks @​DominicBurkart! - feat(xychart): add per-point text labels for xychart line plots

• #7527 b4d0442 Thanks @​notionparallax! - feat(treeView): Extends the existing treeView-beta diagram with features useful for representing file/directory structures.

• #7793 a6f097d Thanks @​SSDWGG! - feat(er): support optional ER attribute types with a ? suffix

• #7772 37f2e36 Thanks @​devareddy05! - feat(gantt): support multiple excludes / includes lines so long exclusion lists can be split into commented groups (#6270)

• #7708 4e63e9d Thanks @​txmxthy! - feat(architecture): add align row|column {ids…} directive to architecture-beta diagrams so authors can declare horizontal or vertical alignment of services explicitly.

• #7760 05223be Thanks @​ngdaniels! - feat(pie): Enhance Pie Chart - Enable donut chart, Set legend position, and highlight slice

• #7251 216e4e9 Thanks @​ydah! - feat(railroad): Add support for Railroad Diagrams (Syntax Diagrams) with four input syntaxes: IR (railroad-beta), EBNF (railroad-ebnf-beta), ABNF (railroad-abnf-beta), and PEG (railroad-peg-beta).

• #7774 e5c75e6 Thanks @​ngdaniels! - feat(xychart): enable rotate label on X-axis

[fullsend-ai-retro]

Retro for PR #557 (dependabot: mermaid 11.12.1 → 11.16.1 in /antora), closed unmerged by a maintainer as part of a housekeeping sweep of several sibling mermaid PRs.

Key finding — non-deterministic verdict flip that lost a real bug. The review agent ran two full iterations against the same commit. Iteration 1 (correctness pass) correctly noticed that antora/supplemental-ui/js/mermaid-init.js hardcodes https://cdn.jsdelivr.net/npm/mermaid@11.10.1/dist/mermaid.min.js, meaning the npm bump in antora/package.json is a runtime no-op — and returned request-changes. Iteration 2 re-ran from a fresh sandbox, all sub-agents returned empty, and the orchestrator posted APPROVED + applied ready-for-merge. The iteration-1 finding was silently discarded rather than preserved or reconciled. This is the highest-signal issue from the run — a proposal targeting fullsend-ai/agents is included below.

Related target-repo bug. The CDN pin is a genuine defect in conforma/conforma.github.io: dependabot updates for mermaid in antora/package.json cannot take effect until the CDN URL is either removed (in favor of the installed package) or tied to package.json. A proposal is included.

Cost / effort tuning — already well-covered, not re-filed. The run cost $5.31 and took ~13 min at claude-opus-4-7 high effort for a 2-file lockfile bump, with ~3 min of sandbox+harness overhead and both iterations re-reading the same skill files. Prior open issues already propose the fixes: fullsend-ai/fullsend#6891 (scope-based effort/model gating), #5777 (diff-complexity routing), #2842 (cheaper model for trivial bot PRs), plus fullsend-ai/agents#257 (pre-review early exit for bot dependency-update PRs). New datapoint for those threads: $5.31 / ~13 min / opus-high / 2 iterations on a mermaid lockfile bump that the maintainer then closed unmerged along with 4 sibling mermaid PRs the same day — the review compute was effectively wasted.

Also observed, not re-filed. The risk-assessment sub-agent failed on both iterations because sonnet-4-5 is not enabled on the Vertex deployment used by this run, and style-conventions had to retry for the same reason. This looks like a deployment/config issue, likely transient — flagging in the summary rather than a proposal.

Agents repo discovered: fullsend-ai/agents@v0.41.0 (10560252b0adaf3a7253046ff16aad4d8d55aa92).

Proposals filed

• Antora mermaid CDN pin makes dependabot updates a no-op (in conforma/conforma.github.io)
