Ashley said r102 will be stable. And it will be released in two weeks tops :)
Ashley said he wants to provide a stable release within the next week or two, it's just a goal.

Since the agenda right now appears to be focused on finishing a stable release, the features you find in r102 (the current beta), are probably, basically, the features you can expect in the stable release. Note that release 95 (last stable release) only had 4 changes in the changelog.
