Where is the latest CMW 6.0.46 ? topic

I'm ready to upgrade to CM12 on my HD+ and I believe I need to locate the latest version of the emmc cmw 6.0.4.6 (I see it is talked about, just cannot find it). I see Leapinlar has 6.0.3.6, should I use that one? Or do I wait for Hashcode to release some new "updates" on installation?

I am currently running 4.4.4 (PACROM), do I need to do a complete wipe/format ect... (very clean state) or just wipe and install it?

Thanks for any feedback.
