Ok guys, somebody must be serious....
1.0.4 was a public beta, after weeks of use Kemper feels it is stable enough (with some minor hitch NOT compromising the functionality: led rings, latency) to get the "release" status and to substitute the 1.0.0 that was to date the only "non-beta" FW release.
1.0.5 is still beta and will be (hopefully soon) substituted by the 1.0.6 (beta?) that should sort out the actual issues (CC#0 crash, pops, sys cache).....without bringing new bugs....

...hopefully...
