yubikey-neo-manager can be deprecated, it is so upstream. I was waiting for it's replacement yubikey-manager-qt to be out of beta first but, feature wise it's already on par.

@joebonrichie As per our package inclusion policy:

Typically, we prefer stable tagged releases. However, this may be waived if:
The software has significant traction (i.e. prerelease)
A bug fix only exists beyond the latest stable release for a git source

IMO yubikey-manager-qt would fall under "has significant traction".

@joebonrichie why don't you give yubikey-manager-qt a go at packaging and let us know how it goes. If there aren't any issues, then we can make a decision.

We have yubikey-manager-qt packaged already, will deprecate yubikey-neo-manager.

Picard's Qt5 support starts from v2.0.0, which is currently in beta.

[Edit]
Actually, I may have misunderstood the purpose of this list. I didn't realize it was for current packages. My bad!

We can now get even closer now with lmms 1.2.0 released yesterday. It should now be possible to build using Qt5 👍
