where are the performance metrics for 1.4 vs 1.3?
The release blog says "...jQuery Mobile 1.4. For this new version we focused on performance improvements" The upgrade guide has a LOT of breaking changes in this release. Unless there is a dramatic measurable reason to do so I would have to pass. Do you see this trend of jqm breaking backward compatibility continuing or is this a one-time thing to address performance issues? I heard the CTO of fameo.us say that jqm is dishonest when they claim good performance based on simple demo pages, when in reality 5FPS is typical in a real jqm app. I have used jqm since 1.0 and love the new responsive layout in 1.4. Unless I can offer real numbers around performance and stability, my company will likely be using Bootstrap for desktop and native for mobile.
