+## Change logs
+It has been a long time since version 0.x.x and now AntOS hits a major changes in its API. From version 1.0.0, AntOS no longer depends on **Riot.js**  in its core UI API. This version introduces a brand new AntOS UI API called **AFX** API which is rewritten from bottom up. The entire AntOS core API is rewritten in Typescript (from Coffeescript)  for better debugging, code maintenance and documenting.
+
+**Browser support**: tested on Chrome, Firefox and partly Safari. Any browser that supports custom elements API should work. May have problem with Microsoft Edge
