Chrome Beta seems to be that sweet spot between reliability and new features - not quite as bleeding edge as the Dev build, but still packed with new stuff earlier than the Stable build. It's generally my personal favorite browser to use as primary, because checking out the new stuff once it's basically no longer buggy is always fun.
Beta 46 was announced for Android yesterday, and it brings a slew of under-the-hood improvements. Even more than that, it brings a ton of features for developers that I'm not even going to pretend to fully understand; if you're the type who likes to dig into code, however, you may want to check out the Chromium blog for more info.
If, like me, you'd rather just reap the benefits of having something a little more modern than Stable and let the devs deal with the rest, then you may be able to pull the update now from Google Play. For those who aren't able to grab it yet, however, we've got you covered with the download below.
The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for this download to be pushed to your devices, which can take days, download and install it just like any other APK.
