Joomla Release

Support for Joomla 1.5 ended in April of 2012

Does that mean your 1.5 site will suddenly stop working? No, your site will continue to work as it always has. However, Joomla’s developers will not be releasing new versions for Joomla 1.5, so you won’t be getting bug fixes or security fixes. For this reason, it’s recommended to migrate from 1.5 as soon as possible,

During the pre release procedure, pre-release packages are posted to Joomlacode and made available to the Joomla Bug Squad for final testing. Typically, these packages are not visible to everyone. However, since there are no security issues included in this release, these pre-release packages were not hidden. This caused third party update services such as Akeeba Admin Tools to erroneously report that these releases were available and as such several hundred sites were updated before the packages were hidden on Monday morning.

In the time since then, additional bug fixes needed to be merged to the code base, causing a need for the release packages to be rebuilt. Unfortunately, there have been technical issues during this process, causing unexpected delays in testing and release of these packages.
