The key is identifying what release gets installers made ... Not every release is going to get a new installer, because it's just too much of a pain in the butt (those installesr are many many megs -- my poor 56k modem that I am forced to use now would catch on fire). So I release installers when I get to a version that I'm reasonable happy with. I would like to redesign a lot of the internals for 42 and really get the code cleaned up. Then I will have people run with 42 for a bit and see if it actually resolves some of these nagging stability problems, and likely 43 or 44 will have installers made.
