Packages are working. However, we have just one inconvenient issue, which I've posted on Lazarus' list but, as you (all) know much about Packages, maybe can help me:
https://lists.lazarus-ide.org/pipermail/lazarus/2019-July/236725.html
It is a bug in Lazarus but it seems that it was fixed by Mattias (see
here) — but I haven't tested yet, but I will.
I will add it tomorrow or Monday. I'm out of office with no PC available.
As we here don't use Lazarus trunk in production but mORMot, I don't know if we keep the current Package implementation, which works but it's showing those Hints by Lazarus when users add mORMot+zcomponent into the same project, or Plan B: remove Conditionals, which add ZeosLib "dynamically" into the Package, and tells users that zcomponent should be included manually if they want to — I prefer last one.
I'm asking Arnaud what he wants. So, don't need to be hurry.

Thank you for your patience.
regards.
PS: I don't see mORMot in
http://packages.lazarus-ide.org anymore?
Has it some robot compiling/sending and if something was wrong, it was removed automatically?
