Well it's been 6 months since we released 1.8.5 and with a few fixes we're due a 1.8.6.
Before we do this though it needs to be tested thoroughly by networks running 1.8 already and until we have a sufficient number of happy folks it won't be released.
So please take an interest, download it from git (or if you wish for Windows I will build a copy) and give it a run through on your network and let us know how it goes.
