ETAF, no, the “nightlies” are the “beta” builds of mt-daapd/firefly (however you wanna call it)
They are supposedly more unstable, but have all the new features.
Currently they are pretty much rock-solid and sport everything you need.
I’d recommend the nightlies over 0.2.4 anytime.
Depending on your platform you just have to download and install one of the nightly builds.
