We don't normally do stable updates this soon, but I'm thinking of getting a new stable release out and then dedicating the next beta cycle to the new multiplayer engine, which will likely take lots of work and testing to get running smoothly given the size and complexity of the feature.
Since we might do a stable release slightly earlier than expected, please make sure you've posted any bug reports you've noticed in r161. As far as I'm aware there's only one current regression in r161 where some shaders may appear slightly different, but apart from that there are no other reports so it looks like r161 is good to go as a stable - unless anyone has noticed any issues but not told us. So please let us know otherwise the issue might not be fixed in time.
If you haven't tested above r158.2 I'd encourage you to give r161 a spin - as far as we know it's pretty solid, and it can be awkward if we receive an important bug report just after a stable update.
