Upgrading from RC4 to Release 3

[David Talmage]

Just last night I installed Plasma Active 3 RC4 on my WeTab. This morning, you 
fine people made the official release!  To upgrade, must I use the USB stick 
again?  Is 'zypper refresh ; zypper update' sufficient? I did that this morning 
and it upgraded only four packages: okular-active, okular-corelib, plasma-
mobile-config-default, and plasma-mobile-config-default-blacklist.
