Yesterday the Joomla project announced the availability of Joomla 2.5.0. This is a security release. So you should have no worries when you upgrade your Joomla site.
Actually, Joomla 2.5 is another milestone in the development of the Joomla CMS and it is marked by dramatical changes. For instance, it’s for the first time that the Joomla CMS includes multi-database support with the addition of Microsoft SQL Server. Other versions of Joomla that were released before were only compatible with MySQL databases. Also, when logged into the control panel Joomla users will be notified each time a new release of Joomla or a new Joomla extension is available. For a detailed list of features that will come with Joomla 2.5, please read the following article
If for some reasons you are unable to update to version 2.5.0, feel free to download Joomla 1.7.4, but please rememeber that Joomla 1.7 will not be supported after February 24th, 2012.
All who are using Joomla as a platform for their websites are welcome to upgrade to Joomla 2.5.0 or Joomla 1.7.4 depending on their needs, because the power and security of Joomla increase with each new release.
