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](mermaid-js/mermaid#6440) [`9ad8dde`](mermaid-js/mermaid@9ad8dde) Thanks [@yordis](https://github.com/yordis), [@lgazo](https://github.com/lgazo)! - feat: add Event Modeling diagram - [#7707](mermaid-js/mermaid#7707) [`27db774`](mermaid-js/mermaid@27db774) Thanks [@txmxthy](https://github.com/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](mermaid-js/mermaid#7604) [`bf9502f`](mermaid-js/mermaid@bf9502f) Thanks [@M-a-c](https://github.com/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: ```yaml config: class: hierarchicalNamespaces: false ``` - [#7272](mermaid-js/mermaid#7272) [`88cdd3d`](mermaid-js/mermaid@88cdd3d) Thanks [@xinbenlv](https://github.com/xinbenlv)! - feat(sankey): add outlined label style, configurable nodeWidth/nodePadding, and custom node colors ### Patch Changes - [#7737](mermaid-js/mermaid#7737) [`e9b0f34`](mermaid-js/mermaid@e9b0f34) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: prevent unbalanced CSS styles in classDefs - [#7737](mermaid-js/mermaid#7737) [`37ff937`](mermaid-js/mermaid@37ff937) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: create CSS styles using the CSSOM This removes some invalid CSS and normalizes some CSS formatting. - [#7508](mermaid-js/mermaid#7508) [`bfe60cc`](mermaid-js/mermaid@bfe60cc) Thanks [@biiab](https://github.com/biiab)! - fix(stateDiagram): `end note` now only closes a note when used on a new line - [#7737](mermaid-js/mermaid#7737) [`faafb5d`](mermaid-js/mermaid@faafb5d) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix(gantt): add iteration limit for `excludes` field - [#7737](mermaid-js/mermaid#7737) [`65f8be2`](mermaid-js/mermaid@65f8be2) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: disallow some CSS at-rules in custom CSS - [#7726](mermaid-js/mermaid#7726) [`1502f32`](mermaid-js/mermaid@1502f32) Thanks [@aloisklink](https://github.com/aloisklink)! - fix(wardley): fix unnecessary sanitization of text - [#7578](mermaid-js/mermaid#7578) [`1f98db8`](mermaid-js/mermaid@1f98db8) Thanks [@Gaston202](https://github.com/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](mermaid-js/mermaid#7592) [`2343e38`](mermaid-js/mermaid@2343e38) Thanks [@knsv-bot](https://github.com/knsv-bot)! - fix(sequence): add background box behind alt/else section title labels in sequence diagrams - [#7589](mermaid-js/mermaid#7589) [`7fb9509`](mermaid-js/mermaid@7fb9509) Thanks [@NYCU-Chung](https://github.com/NYCU-Chung)! - fix(block): prevent column widths from shrinking when mixing different column spans - [#7632](mermaid-js/mermaid#7632) [`3f9e0f1`](mermaid-js/mermaid@3f9e0f1) Thanks [@ekiauhce](https://github.com/ekiauhce)! - fix(sequence): correct messageAlign label position for right-to-left arrows in sequence diagrams - [#7642](mermaid-js/mermaid#7642) [`7a8fb85`](mermaid-js/mermaid@7a8fb85) Thanks [@tractorjuice](https://github.com/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](mermaid-js/mermaid#7523) [`5144ed4`](mermaid-js/mermaid@5144ed4) Thanks [@darshanr0107](https://github.com/darshanr0107)! - fix(block): Arrow blocks in block-beta diagrams not spanning the specified number of columns when using `:n` syntax. - [#7262](mermaid-js/mermaid#7262) [`13d9bfa`](mermaid-js/mermaid@13d9bfa) Thanks [@darshanr0107](https://github.com/darshanr0107)! - fix(block): Ensure block diagram hexagon blocks respect column spanning syntax - [#7684](mermaid-js/mermaid#7684) [`e14bb88`](mermaid-js/mermaid@e14bb88) Thanks [@aloisklink](https://github.com/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](mermaid-js/mermaid#7633) [`9217c0d`](mermaid-js/mermaid@9217c0d) Thanks [@Felix-Garci](https://github.com/Felix-Garci)! - fix(block): add support for all arrow types in block diagrams - [#7587](mermaid-js/mermaid#7587) [`5e7eb62`](mermaid-js/mermaid@5e7eb62) Thanks [@MaddyGuthridge](https://github.com/MaddyGuthridge)! - chore: drop lodash-es in favour of es-toolkit - [#7693](mermaid-js/mermaid#7693) [`afaf306`](mermaid-js/mermaid@afaf306) Thanks [@dull-bird](https://github.com/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 #7120. - [#7737](mermaid-js/mermaid#7737) [`4755553`](mermaid-js/mermaid@4755553) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: improve D3 types for mermaidAPI funcs - [#7737](mermaid-js/mermaid#7737) [`6476973`](mermaid-js/mermaid@6476973) Thanks [@ashishjain0512](https://github.com/ashishjain0512)! - fix: handle `&` when namespacing CSS rules - [#7520](mermaid-js/mermaid#7520) [`8c1a0c1`](mermaid-js/mermaid@8c1a0c1) Thanks [@RodrigojndSantos](https://github.com/RodrigojndSantos)! - fix(stateDiagram): comments starting with one `%` are no longer treated as comments Switch to using two `%%` if you want to write a comment. - Updated dependencies \[[`7a8fb85`](mermaid-js/mermaid@7a8fb85), [`675a64c`](mermaid-js/mermaid@675a64c)]: - @mermaid-js/parser@1.1.1 Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> Co-authored-by: give me a 98K <240642031+inhuman-0@users.noreply.github.com>
