Changelog

The platform

Work on the current branch, not yet in a published version: the library grows from a catalogue into a place to discover, compose, save and integrate.

On the current branch; not in a published version yet.

• NewTen more showpieces: sand, magnets, spectra and a fourth dimension

  Ferrofluid, FallingSand, PaperMarbling, IronFilings, PrismLight, PendulumWave, OrbitSandbox, SnowDrift, Tesseract and VoxelTerrain. Rosensweig spikes that stand up under a magnet, a headline made of sand that crumbles, Jaffer’s exact marbling operators, filings that turn to a dipole field, Snell’s law per wavelength, fifteen tuned pendulums returning to one line, symplectic n-body orbits, snow that settles on the page’s own headings, real 4D rotation, and Comanche column casting over an endless heightmap. Tagged Showpiece alongside the first ten.

  Showpieces
• NewTen showpieces, with a tag of their own

  FluidCanvas, ReactionDiffusion, ClothPanel, ShatterDismiss, ChladniPlate, LightCaster, RainGlass, PopUpCard, ParallaxPortal and InfiniteZoom: real fluid, cloth with working buttons on it, shattering glass, sand finding the nodal lines, cast shadows, refracting rain, pop-up folds, a window into a room, and a zoom that never ends. They are tagged Showpiece rather than New, so the tag stays true after the next release.

  Showpieces
• NewSeventy more components, each a mechanic the library lacked, now the ones marked New

  Proposed with their core mechanic checked against the source, then independently reviewed: 47 of 110 candidates were rejected as duplicates, variants, compositions or too thin. MessageFormat, JustifiedText, TabCoordinator, UrlState, DraftRecovery, FuzzyFinder, FullTextSearch, QueryBar, DockLayout, PairwiseRanker, GeoCoordinateInput, CronEditor, RegexTester, CsvImport, JsonDiff, JsonQuery, AnsiOutput, CurlConverter, SemverRange, CspEvaluator, PathEditor, ImageAdjust, SmartCrop, DocumentScanner, PaletteExtractor, ModelViewer, ExifViewer, ZipBrowser, GifRecorder, MeasureTool, TimeSeriesExplorer, ForecastChart, ControlChart, KaplanMeierChart, TraceWaterfall, ContourPlot, ViolinPlot, HexbinChart, FlameGraph, ErrorBudget, FlowDiagram, Dendrogram, MindMap, ResourceScheduler, TournamentBracket, SlaTimer, TransformBox, SnapGuides, StrokeGestures, RankedChoiceResults, CommentAnchors, CollaborativeText, PeerLink, SlideDeck, ThreeWayMerge, Redactor, ReadabilityMeter, ExpenseSplitter, SqlBuilder, JwtInspector, LogPatterns, RecordMerge, SpacedRepetition, Equalizer, LoudnessMeter, BpmDetector, ChessBoard, Game2048, WordGuess and Solitaire. The previous seventy are no longer tagged New.

  New components
• ImprovedFour duplicate pairs merged, and ScrollProgress hands back-to-top to BackToTop

  UptimeBar is now StatusStrip: intervals take a declared status, incidents, downtime minutes and a date as well as a measured uptime, and the strip gains an uptime override, a legend and a one-tab-stop arrow-key cursor. SpeedDial is now RadialMenu with layout="stack", direction, labels and defaultOpen, and both layouts share the menu-button keyboard model. ScrollList is now ScrollArea with scrollbar="hidden", and AnnouncementBar is now Banner with layout="strip", badge, href and a storageKey that remembers dismissal; ScrollList and AnnouncementBar shipped in 1.0, so both stay as deprecated wrappers. ScrollProgress backToTop is deprecated and renders BackToTop with showProgress, so it moves focus, respects reduced motion and hides properly.

• NewFavorites and collections

  Save any component, block, template, recipe or integration, and file it into collections.

  Saved
• NewComponent health

  Every component page shows its status and only the capabilities there is evidence for — measured from the source and the test suites, not typed by hand.

• NewFind My UI

  Answer two questions and get components, blocks, templates and recipes chosen from the shared tags.

  All optional; existing callers behave exactly as before.
