Hi from Ottawa,
Designing websites is always fun, but it is also important to stay abreast web design industry news. The Joomla! Development Team has just released version 3.4.6! Like Joomla 3.4.5, this is a security-only patch. This time around, the vulnerability discovered affects even broader - anyone using Joomla 1.5, 2.X and 3.X for their websites, are at risk of being compromised, and need to update immediately.
Version 3.4.6 only contains security-related fixes, so in general, it shouldn't affect templates or frontend experience.
If you are using Joomla! 3 (which we recommend to all our clients, because J1.5 and J2 are no longer supported), you can update your site in your Joomla! admin panel, or download the packages on the Joomla! site. Since Joomla 1.5 and Joomla 2 are no longer officially supported, you will have to download the hotfix here, then apply the patch manually.
If you need any assistances with Joomla upgrades or need to restore a hacked Joomla site, we at Joomla Bliss are ready to help you. Give us a call!
