Created on Wednesday, 18 January 2012 19:14

The Joomla Project is pleased to announce the availability of Joomla 2.5 RC 1 for download. Version 2.5 is the second release made within the new six-month release cycle that started with the delivery of Joomla 1.6 in January 2011.

What is this release for?

There are several goals for this release:

  1. To allow advance testing of sites and custom extensions so that site administrators and developers can report any problems before the final release.
  2. To raise awareness that the end of the current development cycle is fast approaching.
  3. To allow testing of the upgrade from version 1.7 to 2.5.0.

When is the final release due?

Joomla 2.5.0  GA (general availability) is due to be released on 24 January 2012. The planned milestone after this date are:

  • 24 February 2012 - Joomla 1.7 reaches end of life and is no longer supported
  • April 2012 - Joomla 1.5 reaches end of life
  • September 2012 - Next version of Joomla is released

Please note that dates may be subject to change depending on availability of volunteers and circumstances beyond our control.

How do I upgrade to Joomla 2.5?

Upgrading from Joomla 1.7 to Joomla 2.5.0 will be very easy. Most users can use the automatic update or install the update archive using the Extension Manager: Install option.

If you are using Joomla 1.5 then you will still be required to migrate your site using the jUpgrade component.

What’s new in this release?

Here is a list, with links to the Feature tracker issue.

In addition, we are using the latest version (11.4) of the Joomla platform in this release. Also, RC1 includes approximately 317 new bug fixes since the 1.7.3 release.

What happens to Joomla 1.7?

Joomla 2.5 is the direct upgrade for Joomla 1.7. Joomla 1.7 will be supported for critical security issues only for a period of one month after the release of Joomla 2.5. After that time, only Joomla 1.5 and Joomla 2.5 will be  supported by the Joomla project. Note that Joomla version 2.5 is a long-term-support (LTS) release and will be supported for at least 18 months.

How can you help Joomla development?

The great news is you don’t have to be a developer to help build Joomla. The Joomla Bug Squad is one of the most active teams in the Joomla development process and is always looking for people (not just developers) that can help with sorting bug reports, coding patches and testing solutions. It’s a great way for increasing your working knowledge of Joomla, and also a great way to meet new people from all around the world.

You can also help Joomla development by thanking those involved in the many areas of the process. Since the release of Joomla 1.6, a whopping 375 issues have been fixed by the JBS. The project also wants to thank all of the people that have taken the time to prepare and submit work to be included in Joomla 1.7 & 2.5, and to those that have worked very hard on the Joomla Platform separation project.
