### [`v8.0.0`](https://togithub.com/mozilla/web-ext/releases/tag/8.0.0)

[Compare

#### 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](https://extensionworkshop.com/documentation/develop/web-ext-command-reference/)
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.
