Release Notes

## Important Notes
In this release we have changed the base class of Entry from a ViewRenderer<Entry, Canvas> to a ViewRenderer<Entry, Grid>. While it is unlikely anyone depends on this behavior, if you do you will need to update your code.

Further in 1.3.0 (the next major release) we will be changing the default Grid row and column definitions to use Star instead of Auto. While it is unlikely, if you currently depend on the default of Auto, you should hardcode the value in preparation for the change.

## Enhancements:

### Android

- Image/ImageCell will no longer reload images when the ImageSource instance is the same for a reused element.
- Minor memory improvements when reusing elements (ListView).
- ListView performance increase. Especially when dealing with lots of labels or nested layouts.
