Today is the day Joomla 1.5 Beta is to be released. Let's hope all the testing and components migration goes well and with ease. The release is exciting news but everyone should proceed with caution. Just some things to think about before installing Joomla 1.5 beta on your live site.
* It is beta software! I know open source beta software is sometimes more stable than the stable release of commercial software but you should wait for a more mature version before installing it on a live site.
* There have been A LOT of changes. This is not a small release upgrade. What that means to you is not all you components and modules may work on this new release. I wouldn't worry about it too much. Just give the developers of your components and modules time to catch up.
I know some of you will undoubtedly install Joomla 1.5 beta on your live server anyway so just know what you are getting yourself into. You early adopters will move the testing along quickly if you give the developers good feedback. Just remember that feedback is good but belligerence is not. Most of the devs are providing their great work free to you me and everyone else so be courteous. :)
