Beta is a name used by software developers that want to test their programs out first- to see if there any bugs present in the programs that can be fixed. One can assume that they use the term "beta" because it's second-rate (or not quite the perfection they seek that is called "alpha").

It is an application or website being tested under real environment to ensure its feasiblity, whether it will be needing a fix or not. It may have different levels of beta. If  \nthe first beta found many bugs then it will be fixed and another beta will be released until it has reached its stability level.\n   For instance, the new Internet Explorer 7 is already in Beta 2. The new Yahoo homepage is launched after a series of beta.

There areseveral testing environ ments\nThere is version Alpha - it means that the product is not finished yet. Its under development and still has many bugs. Its like a foundation of a house, not much.\nThe next version is BETA. Beta is mostly completed product, but it stil has bugs and some changes need to be applied. The BETA version is usually/sometime are given to public for massive testing. This give the idea to the developers what changes need to be made to make the product better. Its like an almost complete hous but the windows and the drywall are not installed yet.

I just switched back and forth successfully from New Mail to Old and back.\n\nIf you're in the old mail and you had previously betatested the new one, just go to the options tab and click on the big "Try Yahoo Mail Beta" button at the top right corner of the tab. \n\nYour mailbox will instantly switch to the new funky version of Yahoo mail.\n\n\n\nJust in case, note that the "switch" is linked to the Yahoo ID, not to the computer nor to the browser, so if it's for a first time switch to the New Mail on a different Yahoo Account, you still have to go to the following adress to upgrade your mail.\nhttp://uk.whatsnew.mail.yahoo.com/

It allows you to switch between all of the applications you have running.  It is important to HOLD the Alt key.. while you only TAP on the Tab key... that will allow you to easily select the application you need.  This is great to use if your computer is freezing and you lose mouse functionality.

7.0 is not beta any more. I would stay with 7.0 because the7.5 beta basically does not work. I had to uninstall it.

go to options and change your location to a European country (ie UK/Ireland). once you go to your mail page you should be asked if you want to try the new beta mail. after the new beta   mail is installed switch your location back. There you go!  If i was not clear enough, go to the link below.

If you want to switch back to the original "face" of yahoo mail, you simply click on the link that says, Switch Back (in line with Sign Out and My Account links at the top), then you're back to the original. But if you decide to switch back to Beta again, then you simply go to the Options tab (on the upper right corner), there would be a purple button there to Try Yahoo Beta again. This process is reversible and should not affect your email. So don't you worry about losing you emails.=D

beta means that the software is not the complete version. There may still be some problems that the creator is working on and has released this version for testing. It is usually OK to use beta software, as i have never found any major problems. Just make sure u update to the completed version when it is released.

Beta means "not ready for release yet".\nOften, the product is being tested by people outside the dev team (these testers are often called "beta-testers").

BETA - means that it's available for public consumption and release but it's not the final product intended to launch. \n\nIt's basically an early release with the possibility of bugs, problems, outages, etc.\n\nThe goal is to learn from the usage of the product, gather user feedback & improve the product and work towards the final release of the product

I agree, changes could be annoying, especially when we find it unfair. But this is still a beta version, they are trying to find the best setting for all. If later on they launch the full version and still keep changing, that will be the right time for us to complain.

In terms of software, Alpha comes before Beta.  I'm sure eventually it will go beyond Beta and will simply be known as Yahoo! Answers.\n\nAlpha refers to software that is still in development and new features are added for testing.  Beta means no new features are added and the software is undergoing active debugging.\n\nMore generally, Beta refers to any software undergoing an initial test.
