Please also consider backporting spdy/3 (or spdy/3.1) to the stable  
1.4.x branch.  
I am asking this because firefox and chrome will probably drop spdy/2  
support  
around the end of February[0], in which case stable nginx servers will  
be  
effectively spdy incapable.

The mainline branch is also stable and reliable for production, and if  
you  
need new features then you should use it, that is why it exists.

Furthermore, SPDY in current mainline version is actually better and  
have  
less bugs, since the stable branch receives only critical fixes. So, if  
you  
are using SPDY I recommend update to 1.5.8 without waiting for spdy/3.

As you have probably figured out, 1.4.x will not get spdy/3 support.  
There  
are no reasons for backporting.
