I installed it through Ubuntu Software (Center) and I still haven't received the update (but I received previous updates). Is just a release time issue (like for Firefox for Ubuntu Canonical which is a bit delayed from the official Mozilla release)? I have Ubuntu 16.10 (64-bit).
[I think it's different from Ubuntu software question (Why don't the Ubuntu repositories have the latest versions of software?) because this software is not maintained by Ubuntu community, but by Adobe itself]
