The release fixes a crash bug in joe loader, I've run into during testing.
Additionally sound distance attenuation has been made less aggressive, and attenuation parameters can be tweaked from VDrift.config now.

The new default parameters for sound attenuation in VDrift.config are:
[sound]
attenuation_scale = 0.914607
attenuation_shift = 0.272928
attenuation_exponent = -0.231374
attenuation_offset = -0.28843
The attenuation is a power function y=a*(x-b)^c+d clamped to the range [0, 1]:
attenuation = scale * (distance - shift)^exponent + offset
The parameters are derived using least squares fit to a number of sampling poins using this great website:
http://zunzun.com/Equation/2/Power/X%20S...%20Offset/
To get the old logarithmic attenuation the parameters are:
[sound]
attenuation_scale = 4.8694110473874862E+03
attenuation_shift = -2.3380252855054809E-02
attenuation_exponent = -2.9380304585176599E-05
attenuation_offset = -4.8686554410866866E+03
The 2014-09-22 release attenuation parameters are:
[sound]
attenuation_scale = 0.5
attenuation_shift = 0
attenuation_exponent = -1
attenuation_offset = 0
If you are curious about how the curves look like, take a look here:

The black curve is the new, other two are the old versions. I've used fooplot to place the sampling points and fed them into zunzun solver. I know this is not exactly user friendly, but the user should not really mess with this settings.
