• FIX: Prevent bottom toolbar from wrapping across two lines on small screens
• ENHANCEMENT: Enabled autoloading of last-read page on app start (and privacy option to turn this off)
• ENHANCEMENT: Geo-location co-ordinates in English and German Wikivoyage are represented with a location marker that links to the Maps app (opens map to show the precise location)
• ENHANCEMENT: Telephone numbers marked with tel: links will attempt to open a relevant app for dialling (e.g., Skype or the People app) when selected
• FIX: Links in Stackexchange ZIMs are now recognized and can be used to open the content
• WORKAROUND: Some Wikivoyage entries have HTML showing in the header, and this is now (temporarily) suppressed (the HTML is interpreted) until the ZIMs are fixed
• ENHANCEMENT: The toolbar icon now switches to a Wikivoyage logo if a Wikivoyage ZIM is loaded

Release 0.9.3 (beta)

• WORKAROUND: Mis-aligned toolbar icons on smaller screens
• FIX: Rogue HTML showing in some pages from recent ZIM archives
• ENHANCEMENT: Better experience when scanning local storage for archives

Release 0.9.0 (beta)

• ENHANCEMENT: Auto-loading of ZIM archives on device storage
• ENHANCEMENT: In-page search / highlighting with Ctrl-F / Alt-F or tap on search button
• ENHANCEMENT: Uses UWP APIs for sotrage: Future Access List so that users do not need to pick their ZIM file every time
• ENHANCEMENT: Dark-themed User Interface
• ENHANCEMENT: Experimental Wikipedia Dark Theme
• ENHANCEMENT: Font scaling for articles and for the UI
• ENHANCEMENT: Cleaner, minimalistic UI (eliminated hamburger menu due to poor navigability)

• ENHANCEMENT: If the TeX string of an equation is available, it will be typeset using MathJax (huge speed improvement)
• ENHANCEMENT: Transform the layout of Wikipedia articles from desktop to mobile style and vice versa (experimental)
• ENHANCEMENT: Disable the display of images, and extract them one-by-one as needed (for slow devices)
• ENHANCEMENT: Only send images in current viewport to the decompressor, and prefetch configurable (by developer) number of images from above and below the viewport
