What's changed

300+ commits have been written to get this new version 8 out of the door (see link to the full changelog at the bottom). Please take a look at the official documentation to know what has changed but expect some breaking changes.

Specifically, web-ext sign has been heavily refactored. Among other things, you can create new add-ons (not just versions) from the command line now 🎉 Unfortunately, this command is not backward compatible with v7.

While we're keeping the v7 branch around to ease the transition, we will mainly fix bugs and introduce new features in v8.
