SA-MP 0.3.8 has been cancelled and won't be released as the main SA-MP branch. There is lack of interest in the downloading feature by most of the existing SA-MP servers.
Since some servers still want the downloading feature to be available now, 0.3.8 will be re-released as a seperate SA-MP version called 0.3.DL, which will be an optional download and have its own server lists. Parts of the existing 0.3.8 code that aren't related to model downloading will make their way in to 0.3.7 updates. Eventually the downloading feature will be part of a main SA-MP release, but the 0.3.8 version will be skipped.
