Yep, for normal wallet (linux / windows) users this a relatively simple update. Good to hear its running fine on your linux desktop.

For masternode owners step 1 is the easy part (updating the Dash software and masternode start it from cold wallet).
Masternode owners will then need to wait for activation of DIP003 on the network (activation through miners support), after which they can proceed to step 2 (registering their masternode as a DIP003 masternode).

This would be a good time for those masternode owners to think about if they want to keep receiving their masternode rewards on their
current mn public address or if they want to receive them on a different wallet address (which can be set during step 2 and be processed when spork 15 goes active).
