Staszek will there there any automatic way to upgrade from beta7 to beta9
Running composer update flarum/core will automatically bring you to beta 9 when it is released. If you upgrade this way without following the upgrade guide to beta 8 from beta 7 you might run into serious issues. Because, among others, that guide specifically mentions extensions might be broken.

Upgrade instructions will only cover the upgrade path from beta 8(.2) to beta 9. We can add a link to the upgrade guide from beta 7 to beta 8, but in the end we assume you to have already upgraded.
