1.7.0 - 2026-04-14

Added

• Hotspot Scale Control: Teachers can now configure default hotspot diameter via activity settings form (0.1 to 3.0 scale)


• Keyboard Navigation: Full keyboard accessibility for 3D viewer - Tab to focus, Arrow keys to navigate hotspots, Enter/Space to activate, Escape to close tooltips


• Screen Reader Support: Tooltips now include role="tooltip", aria-live="polite", and aria-label attributes for proper screen reader announcements


• Touch/Long-Press Support: Mobile users can long-press (0.5s) on hotspots to view tooltips with haptic feedback on supported devices


• Tooltip Animations: Smooth fade-in/fade-out transitions with scale animation (200ms duration) for improved user experience


• Visual Focus Indicator: Canvas shows outline highlight when focused for keyboard users

Changed

• Canvas is now focusable with tabindex="0" and role="application" for better accessibility


• Tooltip icons marked as aria-hidden="true" to prevent screen reader redundancy

1.6.0 - 2026-04-09

Changed

• Three.js Upgrade: Migrated from Three.js r128.0 (2021) to r160.0 (2024), gaining 3+ years of security patches, performance improvements, and WebXR enhancements


• ES Module Architecture: Replaced legacy global THREE object with modern ES module imports (import * as THREE from 'three')


• Self-Hosted Dependencies: Eliminated CDN dependencies for Three.js - now bundled locally via Rollup for improved reliability and performance


• Build System: Added Rollup bundler to convert ES modules to AMD format for Moodle compatibility


• Deprecated APIs: Updated THREE.sRGBEncoding to THREE.SRGBColorSpace (r152+ standard)


• Hotspot Visibility: Increased default hotspot scale from 1.0 to 1.5 and geometry from 0.08 to 0.12 radius for better visibility

Added

• Hover Tooltips: Interactive tooltips showing hotspot type icon, title, and description on hover (see docs/TOOLTIP_SYSTEM.md)


• Smart Positioning: Tooltips follow mouse cursor with automatic edge detection to stay on-screen


• Type-Specific Icons: Font Awesome icons for each hotspot type (info, quiz, audio, video, teleport)


• Rollup configuration (rollup.config.js) for ES module bundling


• New build dependencies: three, @rollup/plugin-node-resolve, @rollup/plugin-commonjs, rollup, grunt-rollup


• Documentation: docs/TOOLTIP_SYSTEM.md with tooltip system details

Removed

• CDN script loading for Three.js core, OrbitControls, TransformControls, and GLTFLoader from view.php

Migration Notes

• See MIGRATION_COMPLETE.md for detailed migration guide and testing checklist


• No database changes required - fully backward compatible


• Run npm install && npx grunt amd to rebuild after updating

[1.5.0] - 2026-04-05

Added

• WebXR Controllers: Full hand tracking and laser pointer support for VR headsets to interact manually with hotspots.


• Text Chat: Added real-time Peer-to-Peer text chat using WebRTC Data Channels in the collaborative mode, alongside the existing voice chat.


• Analytics Dashboard: Added report.php offering visual bar charts and tabular tracking metrics (hotspot clicks, VR starts, etc.) for teachers with mod/gear:manage capabilities.


• Added Analytics button dynamically to the viewer header interface if the user has management permissions.

1.4.0 - 2026-04-05

Added

• Visual Authoring Gizmo: Integrated THREE.TransformControls so teachers can move and position hotspots seamlessly dragging them along X/Y/Z axes in the 3D space, instead of manually clicking points.


• WebRTC Spatial Voice Chat: Integrated PeerJS for serverless P2P voice communication. Users' microphones are automatically spatialized as THREE.PositionalAudio attached to their collaborative avatars.


• Auto Text-to-Speech (TTS): Added a native browser-based Speech Synthesis engine. Users can click the speaker icon on any Info hotspot to have its content narrated aloud automatically.


• Gamification & Branching Scenarios: Hotspots can now be locked until a specific quiz is completed correctly. This enables "Escape Room" style learning where solving puzzles unlocks new areas or information.


• Teleport Waypoints: A new hotspot type that doesn't show a popup but instead seamlessly flies the camera to a new location in the 3D scene, ideal for guided navigation.


• Popup Animation: Unlocked hotspots now appear with a smooth scaling "pop" animation when their condition is met.

Changed

• Performance Optimization: Significant framerate improvements for mobile devices and WebXR by dynamically capping device pixel ratios and hinting high-performance power preference to the GPU.

1.3.0 - 2026-04-04

Added

• New language strings (video_url, video_url_help, hotspot_type_video) in English and Serbian

1.2.2 - 2026-04-03

Fixed
