v15.4.0

Added

• Application: new pauseOnBlur, resumeOnFocus and stopOnBlur properties to configure a game behavior on blur and focus events

Changed

• Core: visibility and focus/blur events are now managed internally through new global BLUR and FOCUS events
• Device: pauseOnBlur, resumeOnFocus and stopOnBlur properties are now deprecated and replaced by their Application counterpart
• Geometry: optimize Rect contains method by using typeof instead of instanceof to identify given parameter type

Fixed

• Renderable : fix a potential issue with a Tile Layer not being properly redrawn when adding or clearing individual tiles
• TMX : properly set the preRenderflag for Tiled layer at runtime (when added to the root container)
• TMX : fix pre-rendering for non-orthogonal maps
• UI: fix dirty flag for base UI elements not being set due to wrong property name (thanks @yuta0315)
