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 #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
