  • Managing if metadata was not loaded.
  • TODO: If recipe is an application(if package_type is defined, we should show another information.
• Added the Dependencies tab showing all the requirements.
• Modified information for each recipe:
  • Now, labels are shown after the description.
  • URLs are shown but slightly sanitized (dropping the protocol).
• Minor changes: renaming, simplifying code, removing comments, etc.
