The Joomla Project is pleased to announce the immediate availability of Joomla 3.1.5. This is a security release addressing a critical level security issue. The Production Leadership Team's goal is to continue to provide regular, frequent updates to the Joomla community. Learn more about Joomla! development at the Developer Site.
The update process is very simple, and complete instructions are available here. Note that there are now easier and better ways of updating than copying the files with FTP.

How can I update from Joomla! 3.0 to 3.1?
Joomla 3.0 to 3.1 is a one-click upgrade with backward compatibility and is NOT a migration. The same is true is for any subsequent versions in the Joomla 3 series. Thus, if you're running a Joomla 3.0 site, please one-click upgrade, within the Joomla! Update component, to Joomla 3.1 to get the new features and the latest bugs fixes.
Will I be able to update directly to Joomla! 3 from Joomla! 2.5?
Moving to Joomla 3.x from Joomla 2.5 will be a mini-migration not an upgrade, although for the core of Joomla! the migration should be simple. However, it is likely that templates for Joomla 2.5 will need modification to work with Joomla 3 as will many extensions. Always test prior to migrating and consult with the developers of any extensions and templates you use.
What is the status of Joomla! 2.5?
Version 2.5 of the Joomla! CMS is a Long Term Support release and support for it will continue until shortly after the release of Joomla 3.5 scheduled for Spring 2014. Joomla 2.5 users do not need to migrate to Joomla 3.1.
What is the status of Joomla! 1.5?
Support for Joomla 1.5 ended in April of 2012 and we continued to support it unofficially until the end of 2012 for medium to high priority security issues.
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.
Moving from 2.5 to any Joomla 3 version is relatively simple, since Joomla has made the process easy for newer versions. Unfortunately, moving from 1.5 is not a trivial task. Fortunately, there are two good extensions that make the process easier:jUpgrade and SPUpgrade.
You have a choice of going straight to Joomla 3.1 or going to 2.5 first. Both jUpgrade and SPUpgrade have versions ready for both versions. Please consult with their documentation on how to migrate from Joomla 1.5 to 3.1/2.5.
For most new/migrated sites, the Joomla! 3 series is the preferred series and starting on it avoids a mini-migration from Joomla 2.5 later down the road. Starting on the Joomla 3 series for a new/migrated site, also provides you with longer backward compatible support (with one-click upgrades) than starting a new site on 2.5 right now, because support for 3.x ends in 2016.
