The improvements in tip can be very important for large applications (for example in some HTTP realted benchmarks tip is 20-40% faster), tip also has better garbage collection leading to lower memory use. Tip also supports around 128 GB of heap on Linux/amd64 versus 8 GB for stable. All that being said, if you are just writing small programs on your machine using 1.0.3 until 1.1 is out is probably not a big deal. Just don't judge Go on performance until 1.1
