Hello everyone!
We’ve just pushed another release on docs-next.strapi.io! 
In addition to the topics mentioned in the original message, we have also:
- added Entity Service API
- added API token, both for the back end and the front end
- added Error handling
- reworked & updated the Configurations, especially for middlewares and admin panel
- reworked & updated the backend customization: routes, policies, middlewares, controllers, services
- updated i18n with the new REST & GraphQL syntaxes and features
- updated GraphQL with new customization features
- and updated the CLI reference (my little finger told me you should try the new fully interactive
strapi generatecommand
)
As we are moving closer and closer to the release, we are always looking forward for your feedback!
