[dependabot]

Bumps mermaid from 11.15.0 to 11.16.1.

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

Note

Low Risk
Lockfile-only semver patch/minor bump for a client-side diagram library; main residual risk is rare rendering or parsing regressions in existing Mermaid blocks, offset by included security fixes.

Overview
Dependency-only update: mermaid is raised from ^11.15.0 to ^11.16.1 in package.json, with the corresponding pnpm-lock.yaml refresh (including transitive updates such as @mermaid-js/parser, cytoscape, dompurify, and optional AWS SDK entries tied to the lockfile graph).

There are no application source changes—diagrams still load through the existing client Mermaid component and dynamic import("mermaid").

The upgrade pulls in 11.16.1 security and bug fixes (notably stronger prototype-pollution protections for user-controlled diagram input, plus CSS/architecture/xychart/radar fixes) and 11.16.0 diagram features that docs can use without code changes (new beta diagram types, treeView/architecture/gantt/ER/pie enhancements).

Subgraph direction edges may break

Medium Severity

Bumping mermaid to 11.16.1 pulls in the 11.16.0 Dagre change that breaks edges into subgraphs that declare an inner direction. The incident-report flowchart uses that pattern (direction TB inside region subgraphs, with edges from Cloudflare into those ALBs), so those cross-subgraph links can fail to render. The 11.16.1 notes cover security and other patches, not that flowchart regression.

[claude]

LGTM — straightforward dependency bump.

What was reviewed: confirmed the diff is limited to package.json/pnpm-lock.yaml with no application source changes; checked that the mermaid component still uses the same dynamic import("mermaid") API surface unaffected by this bump; verified the lockfile's transitive updates (dompurify, cytoscape, AWS SDK) are consistent version bumps, not manual edits.

Extended reasoning...

Overview

This PR is a Dependabot-generated dependency bump of mermaid from 11.15.0 to 11.16.1 (a patch/minor semver-compatible upgrade). Only package.json (one version string) and pnpm-lock.yaml (regenerated lockfile) are touched. No application code, components, or docs content are modified.

Security risks

None introduced by this PR. The mermaid 11.16.1 release notes actually include a security fix (increased protections against prototype pollution, GHSA-c4c3-pg64-4m4v), making this bump a net positive from a security standpoint. The lockfile also picks up a dompurify bump (3.3.3 -> 3.4.13 as a new resolved version alongside the existing one) which is a legitimate transitive dependency of the newer mermaid/iconify chain, not a manual or suspicious edit.

Level of scrutiny

Low scrutiny is appropriate here: this is a lockfile-only, semver-compatible dependency bump for a client-side diagramming library with no first-party code changes. The change is mechanical and fully generated by Dependabot tooling.

Other factors

A bug-hunting pass already ran and found no issues, and additionally investigated whether the mermaid bump causes duplicate dompurify copies via lockfile dedup — ruled out as not a real problem (multiple resolved versions in a pnpm lockfile is normal and expected, not a bug). No outstanding review comments exist on this PR, and there's no prior review from me to reconcile against.
