I have most things that are needed for this update working, and just finished adding a new weapon system including ranged weapons like bow and arrow. It remains relatively in sync with the server although I am working to improve that as well as reducing lag.
A lot of old code is still running that I can get rid of and hopefully free up some space, so right now I am fixing that and hammering out new features to be included in the multiplayer release. My target is to get it to a presentable state and release it before the end of this year, so I have a long struggle ahead of me.
