Thanks for opening this issue! We will help you to keep its state consistent
Hi @LocalHeroPro,
I did not manage to reproduce the issue with 177x branch using PHP v7.3.15

Thanks to check and feedback.
I manage to reproduce the issue:
Branch: develop
Composer version 1.10.1 2020-03-13 20:34:27
It's weird, because in admin panel I have 1.7.6.7 version:

not develop branch as marked on that thread.
It's weird, because in admin panel I have 1.7.6.7 version:
not develop branch as marked on that thread.
It's related to how composer manages PSR-4 and affects all versions. Since it's not a regression we add it for the 1.7.8 :wink:
I reopen since we need to update some dependencies :)
Hi @PierreRambaud! Do you still need to update dependencies or this issue can be closed?
Still needed :)
