I am pleased to announce the release of version 0.1.2 of the YM4R library. The major change of this version is the support of the Google Maps API v2 to display maps from a Ruby application. Maps can also be updated through RJS, without writing a line of JavaScript. Check out the tutorial at http://thepochisuperstarmegashow.com/2006/06/02/ym4r-georuby-spatial-adapter-demo/ to learn more about it.
