Under the hood

We have several major changes that shouldn’t affect the user experience right now, but prepare for much bigger changes coming soon! These include:

  • Early rockcraft-style extensions support
  • The Charmcraft snap is now based on core22

Using Charmcraft

We recommend the Charmed Operator Framework for charm development, but Charmcraft will help you publish charms written in any language. The Charmed Operator Framework enables the development of operators in a simple and straightforward way, using standard Python structures to allow for clean, maintainable, and reusable code.

Happy charming!
