[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
