The API is in Beta. Breaking changes will occur without version changes!
API usage is therefore only recommended if your really need it, but expect that integrations will break and needs updating. We know it's not best practise to change formats in major versions, which is exactly why it's still in Beta.
Version 1 is the current and latest version. It's not yet final due to the many new features we still havn't implemented.
