Copter-3.4-rc4 available for beta testing

For me, something is seriously wrong with 3.4-rc4 on a PixRacer. With the same config, rc3 was great.
I get weird movements, pitch offset slowly changing. After landing, OSD horizont not leveled. (had the same with the crash mentioned, but recalibrated accel and compass)
Where can I get rc3 without building it? Do you have any idea whats going on?
