XMLDecode Now Handles CDATA Sections
In XML, you may want to use markup symbols in regular strings. For example as in the following figure. However, XMLTextDecode in the XML Web component did not handle the "![CDATA [...]]" sections well. Therefore, these sections had to be removed as follows:
This issue was discussed by the community around 2015. As a countermeasure, Taifun  presented the above method. However, this version of App Inventor seems to have solved this problem.
Addition of Barometer
I developed several apps that use the barometric sensor built into the Android Phone and published them at the MIT App Inventor Summit 2014 . At that time, App Inventor could not use the barometric pressure sensor, so I created a small Java program to get the barometric pressure value and called it with ActivityStarter.
