From 0.1 to 0.2:

The template definition yaml format changed. Any custom templates should be updated:
- regions no longer use containerType property
- regions now have a type property which can have the value of row, column, or component
The default theme is now copied into a scaffolded app, so old apps don't have a copy of it. The main custom.scss is also now called base.scss. (Warning: the following may overwrite some of your files. Make sure you're using version control.) To get the default theme, do mulberry update_themes
The locations-map template is now named google-map-phone and google-map-tablet as appropriate.
The pattern for the command line commands has changed; see [[Command Line Interface]]

From 0.2 to 0.3:

The command line utility has moved from /mulberry/bin/mulberry to /cli/bin/mulberry. Update your $PATH to the new location.
Upgrade to PhoneGap 1.3
- If you're developing for iOS, download PhoneGap and run the iOS installer
templates are now called page_defs
- Rename the templates directory to page_defs
- In all your page markdown files, change template to page_def
Theming changes: To get the changes, run mulberry update_themes and resolve any conflicts manually
- Icons have been moved to themes/default/resources/icons.
- All colors have been extracted to themes/default/_settings.scss
- Instead of defining layout in page_def yaml files, use mixins in page_def scss files
  - Any references to the following sass mixins should be changed:
    - column-container -> flex-column-container
    - row-container -> flex-row-container
  - For any custom templates you've created:
    - create an scss file in themes/<my theme>/pagedefs
    - remove all type:<row, column> parameters from the yaml. Apply flex-row-container and flex-column-container to their parent region in scss instead
    - remove all layout: size-fixed from the yaml. Apply fixed-flex-region to the element in the scss instead
