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.
Extension is only one thing, it's obvious for me that extensions will not be compatible.
I recommend you to upgrade as soon as possible, you are running a vulnerable Flarum installation β οΈ
I don't remember any announcement, that beta7.2 is vulnerable. Was there any? I know I should upgrade, but as I said, I cannot do it easily, because some extensions are important, but not finished for beta8 (or maybe finished, but I have to test it). I'm going to do it soon, but I may not do it before release of beta9
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.
I think it's bad assumption. I think many people still have beta7, to there should be at least guide on how to upgrade from beta 7 after release of beta9. I assume it's going to be different, so linking old guide will not help.
Anyway, good to know that new release is almost readyπ
EDIT: I meant there should be guide on how to upgrade from beta7 to 8 after release of 9. I suppose after beta 9 release composer will try to do direct upgrade to beta9, instread of beta 8. So some command in 7->8 guide will probably change.
