Although personally I don't like Chromium or Chrome that much because, I'm a bit of a freak and I certainly don't like their simplicity. Plus, beware if you use Chrome because sometime ago a certain rumor got out saying that the big G is using Chrome to collect our personal data!, my mother warned me about this :P.
Few of the main improvements in this Chromium 12th release...
*. Hardware accelerated 3D CSS -
|The HTML5 3D "Sheep Experiment", Google says "no animals were harmed" :)...|
This means that whenever you go into a web site with 3D CSS animations, etc now Chromium will use your GPU (VGA) to generate those 3D effects thus minimizing the CPU load + enhance the power usage as well since a GPU is especially designed to deal with graphics rather than a CPU thus they are almost always more efficient while dealing with graphics.
There is the Chrome (not Chromium) 12's little 3D adventure with few animals if you like, oh it's only for MS Vista or Mac OSX 10.6 or above users, bugger :/.
*. Better protection against Malicious files -
Now, any fool can warn you about a malicious website before you enter if they already know about it. But with Chromium 12 (Chrome 12 also have it) now the web browser has the ability to analyze certain "patters" when it comes to URLs thus having the ability to foresee "the danger". Of course this does not mean that we're 100% safe yet it's more than welcome feature to have around, don you think? :).
*. No more Google Gears support.
*. Enhanced screen-reader support added.
These are of course a very few to mention. Anyhow, if you use Ubuntu 11.04 Natty Narwhal, 10.04 or 10.10 then you can install Chromium 12 by using the official PPA channel. To do that, open your Terminal and enter the below command.
sudo apt-add-repository ppa:chromium-daily/stableThat should do it for you!. Enjoy.
sudo apt-get update
sudo apt-get install chromium-browser
