Changelog

All notable consumer-facing changes to ChronoLaneJS are documented here. ChronoLaneJS is an open-source React and TypeScript calendar and scheduler.

The project follows Semantic Versioning. Git tags and npm are the canonical version record; this file provides the curated upgrade context that accompanies the automatically generated GitHub release notes.

Unreleased

2.1.0 - 2026-08-25

Added

  • Published every documentation page at a stable, crawlable URL with prerendered content, canonical metadata, and sitemap coverage.
  • Added focused, illustrated guides for event movement and resizing, resource scheduling, time zones and localization, custom renderers, accessibility, and Vite and Next.js integration.

Changed

  • Reorganized the documentation around reader tasks and split the TypeScript API reference into focused component, data, interaction, renderer, and localization references.
  • Aligned the website, repository, package manifest, and release description on the open-source React and TypeScript calendar and scheduler category.

Fixed

  • Improved built-in view accessibility with explicit month-grid ownership, accessible month-day controls, and forced-color focus and selection states.

2.0.0 - 2026-08-24

See Migrating from v1 to v2 before upgrading.

Breaking changes

  • Replaced the ambiguous event-editing contract with stable selection and opening semantics. canEditEvent is now canOpenEvent, and onEventEdit is now onEventOpen. Selection uses click or Space; opening uses double-click, double-tap, or Enter.
  • Added rendered-occurrence context to event predicates and semantic callbacks. Applications can now distinguish the visible view, day, and resource without receiving a clipped event in place of the source event.
  • Expanded the required CalendarMessages registry with multiDayRegionLabel, eventMoveHandle, eventMoveTarget, and eventResizeHandle.
  • Renamed TimeGridEventDropPosition to TimeGridEventPosition so movement and resizing share one position contract.
  • Added the required layout discriminator to TimeGridEventSegment. Custom time-grid event renderers can distinguish timed and dedicated multi-day occurrences.

Added

  • Pointer, touch, and keyboard event movement from the event surface, with live previews, explicit source/destination positions, cancellation, and accessible announcements.
  • Pointer, touch, and keyboard event resizing with independent resizeStep precision, live geometry, per-edge permission checks, and clear edge affordances.
  • An opt-in dedicated multi-day event region through multiDayEventLayout="dedicated".
  • Arrow, Home, End, Page Up, and Page Down traversal for selectable time-grid slots.
  • Additive raw event-root callbacks through eventInteractions, including shortcut metadata composition.
  • Event detail tooltips and ellipsis handling for content that does not fit its rendered event surface.
  • Focused Storybook interaction sections for selection/opening, movement, resizing, slot selection, keyboard navigation, and customization.

Changed

  • WeekView columns now remain fluid down to a 96px minimum before scrolling horizontally. Set slotSizing={{ minWidth: 0 }} to keep fully compressible columns.
  • Dedicated multi-day movement and resizing use whole calendar-day steps while preserving wall-clock fields across daylight-saving transitions.
  • Time-grid, month, and agenda ownership was simplified so collection owners map their own structural elements and renderers without pass-through component or hook abstractions.
  • Event movement uses the event body instead of a permanent move button; resize hit zones remain visually hidden until hovered, focused, or active.

Fixed

  • Preserved source-event identity and full duration across clipped, overnight, duplicate, multi-resource, moved, and resized occurrences.
  • Kept time-axis labels and interaction proposals stable across daylight-saving transitions.
  • Kept week columns readable in narrow containers.
  • Aligned event, slot, and resize-handle keyboard focus visuals with hover and active interaction styling.
  • Updated stylesheet consumers after simplifying the shared navigation component name.

1.0.1 - 2026-08-16

Fixed

  • Polished the GitHub Pages presentation and documentation routing.

1.0.0 - 2026-08-16

Added

  • First stable release of the typed React calendar package.
  • View-specific Calendar props, direct built-in views, resource grouping, range-owned navigation, localization registries, renderer contracts, and controlled selection APIs.
  • Bundled production styles, a GitHub Pages playground, Storybook scenarios, exhaustive API documentation, consumer-build verification, and automated trusted publishing.

Changed

  • Established the stable public API from the release-candidate series, including strict time-grid scale and slot-sizing contracts.

0.1.0-rc.0 - 2026-08-16

Added

  • First public release candidate of ChronoLaneJS under npm's next tag.
