Reader / UX: finger swipe gesture can now be used to turn pages (requires touch screen).Reader / text display: fixed left/right/justify text alignement (“start” can be left or right depending on document language), “automatic” is now “default” with changed SVG icon to avoid confusion.Reader / navigation history: hyperlink activation now correctly sets the landmark for previous/next navigation.Reader / MathML: native rendering prioritization of authored alt-text if present, with the option to dig further / deeper into the MathML structure (useful with screen reader specialised plugins).Reader / image zoom: major feature update from initial proof of concept, better user experience (finger touch, trackpad gestures, mouse wheel, keyboard) support for raster/bitmap images as well as SVG markup.
