Google Chrome 23.0.1243.2 Dev
Think of the Dev channel of Google Chrome as an alpha build, Chrome’s equivalent of Firefox Aurora. It’s one step forward from the untested nightly builds of Chrome Canary, but it’s still a long way from the finished article, never mind the more reliable beta.
That said, Chrome Dev obviously remains a key part of the Chrome development cycle, as it’s the first release specifically designed for wider public consumption. Unlike Canary, you can’t run Google Chrome Dev side-by-side with the stable, final version, although you could fashion your own clumsy workaround by running Chrome Dev alongside the portable version of Chrome.
If you do go down the Dev path, be prepared to enjoy a much less stable experience, although in return you’ll be testing cutting-edge features that won’t be available to other users for weeks if not months.
What's new in Chrome 23? Very little apart from some bug fixes. Chrome 23 is now based on the Chromium v8 core (3.13.1.0) and fixes various issues.
Note that this is the Dev channel and should be used with some caution.
Verdict:
If you really feel you need the latest Chrome, this is for you. However, although you might get some important fixes, and the latest Chromium core, we also find the Dev version to be fairly unstable.
