For those, who use latest and latest-git files in scripts. Those files are deprecated — I'll remove them in month starting from this date. I suggest you using site-latest file that has the following syntax:
x.y|z|dd.mm.yyyy|where x.y is base kernel version, z is pf-kernel release, dd.mm.yyyy is release date. Here is the example for current version:
3.3|5|7.05.2012|URLs' structure isn't going to be changed, but you should construct them by yourself. Please, correct your scripts ASAP.
