As you may know, in a couple of weeks we will be releasing Moodle Mobile version 2.0
This new version is completely built from scratch using the amazing Ionic framework (http://ionicframework.com/)
If you have created a custom version of the application or have developed new plugins, don’t worry, we will be updating the developer's documentation so you can become familiar with the new APIs and migrate the code as soon as possible. One of the advantages of using Ionic (besides being built on AngularJS) is that currently there are plenty documentation and books published about those popular frameworks.
If you are using the Custom CSS URL functionality, you will have to upgrade the styles to match the new application; we are also creating documentation with the basic styles you should apply to customize the look and feel of the app.
Remember that you can see a static prototype of the new application here: http://prototype.moodle.net/mobile/moodlemobile2/
