As promised in the discussions of how the mod would develop in tandem with the standalone game, Day Z's mod version has been patched to 1.7.3 with contributions from the wider community (as opposed to just the original dev team.) Discussing the patch on the Day Z forums, Rocket posts a list of everyone who has contributed to the latest update, and encourages others to get involved: "There is much being done, new features and content. Official support is also being made available to community development team members for some requests, where possible."
There are no new features in this patch, sadly, as it's all bug fixes and tweaks, and although dogs are "in" they're no workable yet due to some missing features. Dogs, it seems, will have their day(z).
