What many people don't realize is that Chrome is just the beginning, the first branch on a very large tree of code that spans numerous development milestones. There's the Chrome that people use and on a daily basis, and then there's everything else. The good stuff — like Android link push and extension sync — doesn't always make it into the stable builds as early as we'd like, and until it does, Chrome's many development branches are the place to find them.

Chromium snapshot builds
This is as bleeding edge as you can get when it comes to pre-release builds, and the least stable of all development trees. Here, changes are introduced on a daily basis, fixing some things, while breaking others, and serves as the testing ground for more stable Chrome releases. As the name implies, a snapshot is taken each night at regular intervals, so depending on the state of the codebase, it's very likely things won't work. It's important to note that Chromium in this state isn't actually "officially" Chrome; instead, it serves as an open-source development project upon which Chrome is based. That means things like Flash and h.264 decoding aren't included by default — something to keep in mind when watching all those double rainbow parodies on YouTube.Canary builds

Developer builds
This branch has been around since Chrome's inception, and offers a more stable testbed for developers to work on extensions and other aspects of Chrome development. Once certain features move from the experimental testing stages, they begin to appear in the development branch for bug fixing and improvements, with the eventual goal of becoming full-featured parts of a stable Chrome release. It's important to note that the differences between platforms and features become more apparent here; extension support was previously missing from Mac and Linux builds from quite some time, and extension sync seems to be the same.Beta releases
As Google describes it, the beta branch allows users to "try out the newest tools while they're a little rough around the edges." Features that appear in beta builds are now officially part of the Chrome roadmap, but require a wider user test base to ensure they are ready for prime-time. Stability for core components is usually not an issue here, but tread carefully where new features and settings are concerned.Stable releases
Finally, this is the release of Chrome that most are familiar with, and probably the one with which you're reading this right now. Available for all platforms from the Google homepage, the official release of Chrome includes all those fancy features like browser sync, automatic updates and plug-in support that we've come to expect. Not much to see here — you know what to expect.Lead image via Flickr user casasroger.
