Google has just updated the developer builds of Chrome, so users who are already running this particular build right now should get the new releases as soon as possible.
The company hasn't provided too many details about what's fixed in Google Chrome 37.0.2031.2 Dev, but Daniel Xie, one of the developers working on the project, said that this new build is focused on fixing bugs and addressing performance issues on all supported platforms.
As you probably heard by now, the dev builds that are currently offered to Windows users also come with a 64-bit version that's said to excel in terms of speed, security, and reliability, so in case you've already deployed this new flavor of Google Chrome on Windows, make sure that you update as soon as possible.
