I have released 17.2. This is essentially a catch-up-to-CVS release. If you don't upgrade nothing astonishing will be missing from your life, unless you are using MA, which has been worked on some since 17.1. I installed a performance enhancement submitted by Pete Shinners, who said: "I've got a quick optimization for the arrayobject.c source. it speeds my usage of numpy up by about 100%. i've tested with other numpy apps and noticed a minimum of about 20% speed."
