Joomla! 1.0.9 [ Sunshine ] is now available as of Monday 05th June 2006 18:00 UTC for download here.

We suggest that all Joomla! users upgrade to this version. 

1.0.9 contains the following changes:

• 12 Low Level Security Fixes
• 160+ General bug fixes
• Several Performance enhancements

Although this release contains 12 security fixes, as they are of a low level nature, this release is being characterized as a Stabiility/General release.  If you are running 1.0.8, you are advised to upgrade to 1.0.9 as it fixes several annoying non-critical errors in 1.0.8

1.0.9 is available as a Full Package, which contains all Joomla! files and Patch Packages which contain only the files that have been changed by the Stability work conducted from previous Joomla! 1.0.x versions.

• 1.0.9 Download
• 1.0.9 Version Information

New to Joomla! or starting a new site

Are you a new Joomla! user?  Confused as to which of the 30 available packages to dowload? 

The answer is simple.  If you are creating a site for the first time, you will need the Full Package file:

• 1.0.9 Stable Full Package

The other packages are for those users who have already have an existing Joomla! site and wish to upgrade to the latest version.

Upgrade Instructions

Upgrading from any version of Joomla! 1.0.x to 1.0.9, simply involves overwriting your current sites files, with the files in the proper Patch Package that applies to your site.  This is also the case for those users who are currently using a 1.0.9 Beta version. 
So if you are running Joomla! 1.0.5, you will need the 1.0.5 to 1.0.9 Patch Package.

This can be done by either uncompressing the Patch Package and then using an FTP client to transfer these files to your server and overwriting existing file.  If you find errors after the process, ensure that all files were properly transferred.  There have been verified reports of some FTP clients not properly transferring files across to a server - without notifying the user of such a problem.

If your Web Provider gives you access to your site via some sort of Web Admin panel like CPanel or Plesk, you can use the syetems file manager to upload the Patch Package file to your server and then extracting the package file and overwriting all the files on your server.

More information can be found on the Forums and if at any stage you are unsure, then search the forums for posts on the subject.  Most will be found in the Upgrading Forum.

Backing Up

Before undertaking an Upgrade or Conversion, it is extremely important that you backup your site Database and if possible, also you site files.  While we try to ensure that an Upgrade or Conversion process is relatively straightforward, we cannot garuantee that this will always be the case for every user.  So it is imperative that users take protective measures in case they face problems after the Upgrade or Conversion.

Package Integrity

To ensure the integrity of the files you are downloading, you are advised only to download from the 'Official Source' on the Ofifical Joomla! Forge.  As an extra security measure we now make available the MD5 checksum values of the respective package files, to allow people to do integrity checking.
