Releases

mermaid@11.15.0

Minor Changes

#7174 0aca217 Thanks @milesspencer35! - feat(sequence): Add support for decimal start and increment values in the autonumber directive
#7512 8e17492 Thanks @aruncveli! - feat(flowchart): add datastore shape

In Data flow diagrams, a datastore/warehouse/file/database is used to represent data persistence. It is denoted by a rectangle with only top and bottom borders, and can be used in flowcharts with A@{ shape: datastore, label: "Datastore" }.
#6440 9ad8dde Thanks @yordis, @lgazo! - feat: add Event Modeling diagram
#7707 27db774 Thanks @txmxthy! - feat(architecture): expose four fcose layout knobs for architecture-beta diagrams (nodeSeparation, idealEdgeLengthMultiplier, edgeElasticity, numIter) so authors can tune layout density and spread overlapping siblings without changing diagram source
#7604 bf9502f Thanks @M-a-c! - feat(class): add nested namespace support for class diagrams via dot notation and syntactic nesting

If you have namespaces in class diagrams that use .s already and want to render them without nesting (≤v11.14.0 behaviour), you can use set class.hierarchicalNamespaces=false in your mermaid config:
```
config:
  class:
    hierarchicalNamespaces: false
```
#7272 88cdd3d Thanks @xinbenlv! - feat(sankey): add outlined label style, configurable nodeWidth/nodePadding, and custom node colors

Patch Changes

#7737 e9b0f34 Thanks @ashishjain0512! - fix: prevent unbalanced CSS styles in classDefs
#7737 37ff937 Thanks @ashishjain0512! - fix: create CSS styles using the CSSOM

This removes some invalid CSS and normalizes some CSS formatting.
#7508 bfe60cc Thanks @biiab! - fix(stateDiagram): end note now only closes a note when used on a new line
#7737 faafb5d Thanks @ashishjain0512! - fix(gantt): add iteration limit for excludes field
#7737 65f8be2 Thanks @ashishjain0512! - fix: disallow some CSS at-rules in custom CSS
#7726 1502f32 Thanks @aloisklink! - fix(wardley): fix unnecessary sanitization of text
#7578 1f98db8 Thanks @Gaston202! - fix(class): self-referential class multiplicity labels no longer rendered multiple times

Fixes Class diagrams: Self referential multiplicity is displayed multiple times #7560. Resolves an issue where cardinality labels on self-referential class relationships were rendered three times due to edge splitting in the dagre layout. The fix ensures that each sub-edge only carries its relevant label positions.
#7592 2343e38 Thanks @knsv-bot! - fix(sequence): add background box behind alt/else section title labels in sequence diagrams
#7589 7fb9509 Thanks @NYCU-Chung! - fix(block): prevent column widths from shrinking when mixing different column spans
#7632 3f9e0f1 Thanks @ekiauhce! - fix(sequence): correct messageAlign label position for right-to-left arrows in sequence diagrams
#7642 7a8fb85 Thanks @tractorjuice! - fix(wardley): allow hyphens in unquoted component names

Multi-word names containing hyphens — e.g. real-time processing, end-user, on-call engineer — now parse without quoting, bringing the grammar in line with the OnlineWardleyMaps (OWM) convention. A->B (no-space arrow) still tokenises correctly.
#7523 5144ed4 Thanks @darshanr0107! - fix(block): Arrow blocks in block-beta diagrams not spanning the specified number of columns when using :n syntax.
#7262 13d9bfa Thanks @darshanr0107! - fix(block): Ensure block diagram hexagon blocks respect column spanning syntax
#7684 e14bb88 Thanks @aloisklink! - fix: loosen uuid dependency range to allow v14

Mermaid does not use any of the vulnerable code in CVE-2026-41907,
but this allows users to silence any npm audit alerts on it.
#7633 9217c0d Thanks @Felix-Garci! - fix(block): add support for all arrow types in block diagrams
#7587 5e7eb62 Thanks @MaddyGuthridge! - chore: drop lodash-es in favour of es-toolkit
#7693 afaf306 Thanks @dull-bird! - fix(quadrant-chart): allow CJK, emoji, Latin-1 accented characters, and other non-ASCII text in unquoted axis/quadrant/point labels.

Previously the lexer only matched ASCII [A-Za-z]+ for text tokens, even though the grammar referenced UNICODE_TEXT. Bare Chinese, Japanese, Korean, emoji, and accented Latin characters in labels caused a parse error. Added a [^\x00-\x7F]+ lexer rule to emit UNICODE_TEXT and included it in the alphaNumToken grammar rule.

Fixes Quadrant Chart render fail #7120.
#7737 4755553 Thanks @ashishjain0512! - fix: improve D3 types for mermaidAPI funcs
#7737 6476973 Thanks @ashishjain0512! - fix: handle & when namespacing CSS rules
#7520 8c1a0c1 Thanks @RodrigojndSantos! - fix(stateDiagram): comments starting with one % are no longer treated as comments

Switch to using two %% if you want to write a comment.

#7658 675a64c Thanks @aloisklink! - fix(parser): bundle langium/chevrotain

This should silence warnings about lodash-es 4.17.23, which chevrotain@11.1.1 is pinned to, but is not vulnerable to.

And this avoids warnings when langium v4 is installed on Node.JS v20.0.
