(Google Chrome's Open Source Version)
Using Google Wave, I've finally found a reason to use Chromium for more than a few minutes a day. But, a big issue with using it, Keeping it up to date.
I found a few tools which can help keep Chromium up to date with the latest version.
First the Mac OS/X updater. This come from TechCrunch, you can read about it on their site.
Direct download link for TechCrunch's Mac Chromium Updater .
Next up, the Windows OS updater. It comes from tlokzz, a nice easy/fast Chromium Updater.
It has built in download manager and auto installer. The Chromium Updater download is a RAR file. If you do not have a program to extract RAR files, 7-Zip is a great Open Source program to use.
Note: You can also directly download the latest Chromium Build here
