Changelog

Release history of Citia Design System: 2.0.1 (NuGet package), 2.0.0 (universal, bilingual, complete catalog) and 1.0.0 (first release).

The format follows Keep a Changelog. Versions follow SemVer: a change to a token or class that forces a project to change its markup raises the major version. The same text is in CHANGELOG.md at the repository root.

2.0.1 - 4 Nov 2026

First version published as a NuGet package for every Citia app; see Releases and updates.

Fixed

<partial name="_DsHead" /> without a model no longer throws on pages that have their own model (every Razor Page with a PageModel). The partial now accepts any model and falls back to the default HeadOptions.

Added

Package metadata: readme, project URL, tags and release notes link, shown in the NuGet feed.
tools/smoke-test.ps1: installs the packed package into a new Razor Pages app and checks rendering, assets, language, validation and toasts, in Development and as a published app.
Citia NuGet feed at https://design.citia-engineering.com/nuget/v3/index.json, served by the documentation site. tools/release.ps1 checks the changelog, contrast and smoke test before it publishes; tools/deploy-site.ps1 deploys the site.

Changed

The documentation site shows the version of the package it is built with, so site and package cannot drift.

2.0.0 - 2 Nov 2026

Version 2 turns the library extracted from a single product into a universal design system for ASP.NET Core (.NET 10). No breaking change is intended; see Migrating from v1.

Added

A complete component catalog covering shadcn/ui, Material 3, Tailwind UI application UI and daisyUI 5: actions, text and choice fields, pickers, upload, data display, feedback, overlays, navigation and layout. See Coverage.
English and Indonesian everywhere: documentation, C# strings (DsText, culture-aware Fmt) and JavaScript (addMessages, locale).
Tokens: type roles, state layers, spring and enter motion, target sizes, z-index scale, --ds-focus.
State matrix on every component: pointer, keyboard, selection, disclosure, availability, validation, activity, content, drag, variants and environment.
JavaScript: one module per family, the DS API (init, configure, addMessages, theme, toast, confirm, guard and more), ds:* events and DS.init(root) for partial updates.
User preferences in accessibility.css: reduced motion, reduced transparency, more contrast, forced colours.
Right-to-left support through logical properties.
Documentation: getting started, foundations, component pages, patterns (page, forms, data, workflows, feedback), content (writing, voice and tone) and reference (JavaScript, Razor and C#, coverage, migration).
Many more tag helpers and partials; see Razor and C# API.

Changed

Themes are named light and dark; tps and tps-dark remain as aliases.
Documentation slugs are English; version 1 addresses redirect.
All examples and copy are domain-neutral; the TPS-specific tank illustration tokens and examples were removed.
HeadOptions defaults to light and dark.

Fixed

Focus ring colour keeps at least 3:1 against both surfaces.

1.0.0 - 2 Nov 2026

First release, extracted from INTEGRA TPS Integration (branch feature/tps-integration, commit 88cd8e4).

Added

DTCG tokens in tokens/tokens.json: primitive palette, light and dark themes, 17 type roles, spacing, radius, border, shadow, size, z-index, motion and opacity.
tools/tokens.cs (.NET 10, one file): builds the CSS, JSON, icon and reference outputs and checks WCAG contrast pairs.
tools/css.ps1: Tailwind CSS standalone and daisyUI with SHA-256 verification, Windows and Linux, without Node.js.
Razor Class Library Citia.DesignSystem: tag helpers ds-icon, ds-pill, ds-tag, ds-empty; partials _DsHead, _DsScripts, _DsIconSprite, _DsToast, _DsConfirmDialog, _DsLeaveDialog, _DsPager, _DsSortHeader, _DsPageSize, _DsSidebarNav; helpers Icon, Tone, ToastMessage, ListSort, ListPage<T>, QueryUrl, NavModel, Avatar, Fmt, Wib.
ds-* component CSS and a prebuilt ds.css for applications without Tailwind.
ds.js: three-mode theme, collapsible sidebar, navigation groups, drawer, back links, dialogs and confirmation, toasts, unsaved-changes guard, export lock, copy, password toggle, auto-submit, submit once, pinned table columns, tree rows, ARIA combobox.
73 icons, Manrope variable font and the Cally calendar.
