Introducing new build stuffs at this point seems counter-intuitive (it's also too hot for me to bother, sorry!). So have decided to push MPD 0.23.x into U3 or later.
This kind of Means U2 is more or less feature complete. Will give this a run for a few more days release a beta, and then a full release a few days after.
I know there are some folks with problems installing upmpdcli, or getting MPD to even start. Unfortunately I havn't been able to replicate these two issues... So, if you guys have access to the test builds, kindly try it now and see if it works for you now (or not).
