What's New

v9.4 - In Planning​

Scope tracked in the v9.4 milestone.

@deck.gl-community/layers​

  • DependencyArrowLayer - NEW directional marker layer for dependency links with path, line, or arc routing.
  • PathOutlineLayer and PathMarkerLayer now use deck.gl v9-native sublayers for outlined paths, dashed strokes, and pixel-sized directional markers, restoring the path outline and marker example.

@deck.gl-community/infovis-layers​

  • Added generic animation, block, fast-text, UTF8 Arrow string-view, view-layout, and viewport-bounds helpers for trace-style visualizations.

@deck.gl-community/timeline-layers​

  • TimeAxisLayer now supports adaptive trace-style duration and timestamp grids plus exported tick formatting helpers.

@deck.gl-community/trace-layers​

  • Trace graph data, layout, style, runtime-ref, Chrome trace, Perfetto trace, and Arrow ingestion APIs now ship from normalized trace, layers, loaders, and react package subpaths.
  • TraceEngine now owns mounted trace selection, collapse, layout, prepared scene, and diagnostics state below React; DeckTraceGraph renders an engine instead of receiving the full controlled trace-view state directly.
  • TraceChunkStore now exposes source-owned graph-data materialization and retained-state diagnostics for incremental windows, while TraceStoreLayer composes that flow as a low-level deck layer.
  • DeckTraceGraph, deck controllers/layers, trace loaders, and the Tracevis React surface now consume shared @deck.gl-community/panels, @deck.gl-community/widgets, and @deck.gl-community/infovis-layers APIs instead of vendored upstream copies.
  • Added the website Tracevis example for exercising trace loading, selection, catalog, and Studio visualization settings workflows.

@deck.gl-community/react​

  • <Panel /> - NEW React component for rendering reusable @deck.gl-community/panels definitions in React and MDX trees.

@deck.gl-community/widgets​

  • PanelWidget - NEW generic deck adapter for any panel-owned PanelComponent.
  • Thin named adapters now cover real panel containers plus specialized toolbar and toast components without duplicating panel rendering logic.
  • OmniBoxWidget now accepts renderResultsSummary for rendering a compact caller-provided summary above dropdown results.
  • OmniBoxWidget now accepts shared command manager search prefixes for command-mode Tracevis integrations.
  • ModalPanelWidget inherits floating, draggable, custom-styled modal support from ModalPanelContainer.
  • createStudioSettingsWidget and updateStudioSettingsWidget now host the shared Studio settings panel through deck widget chrome.

@deck.gl-community/panels (NEW module)​

A new module for deck-independent panel composition and small application UI.

  • PanelManager - mount compatible panel-managed UI into a plain HTMLElement

  • PanelComponent - NEW root lifecycle for mountable panel-owned UI.

  • Panel now inherits the shared PanelComponent lifecycle, including direct mounting.

  • Panel/container composition APIs extracted into a dedicated package

  • Stand-alone documentation and examples for panel composition outside deck.gl

  • Composite panels now accept ordered Panel[] arrays, shell containers render direct panel inputs.

  • ModalPanelContainer now supports floating non-blocking dialogs, draggable dialog handles, left placement, custom dialog/content styles, and content-rendered close controls.

  • SplitterPanel - NEW composite panel for resizing two panel groups horizontally or vertically.

  • BinaryDataPanel - NEW reusable panel for compact hex and ASCII previews of caller-supplied binary data.

  • ArrowTablePanel - NEW reusable panel for bounded Apache Arrow table previews with row, column, batch, nested-list, matrix, temporal, and loaders.gl wrapper support.

  • ArrowSchemaPanel - NEW reusable panel for Apache Arrow schema inspection, including schema, field, child, matrix, and temporal metadata with JSON metadata formatting.

  • ArrowBatchesPanel - NEW reusable panel for inspecting Arrow record batches, row counts, cumulative row ranges, and column counts.

  • StudioSettingsPanel - NEW schema-driven settings surface with grouped controls, compact navigation, and visual routing-shape controls.

  • SettingsPanel now renders multi-select descriptors through the shared searchable panel selector.

  • SettingsPanel numeric range inputs can apply descriptor-level trailing debounce via sliderDebounceMs.

  • SettingsPanel and StudioSettingsPanel select menus can render option descriptions and grow to fit long labels; StudioSettingsPanel also accepts settingRowLayout: 'fit-labels' when controls should claim width from short labels.

  • ModalPanelContainer and SidebarPanelContainer trigger icons can render data/http(s) image URLs as CSS mask icons.

  • CommandManager - NEW shared command registry for keyboard shortcuts, widgets, and host automation surfaces.

  • SettingsManager - NEW UI-agnostic helper for settings snapshots, structured change descriptors, and descriptor-aware local storage persistence.
