Whether you are starting a new project with Joomla / Fabrik or maintaining an existing Joomla / Fabrik web site it is important -
essential really - that you keep your web-site software versions up to date.
Why should you keep up to date
1. Support
PHP, MySQL, Joomla and Fabrik all have a limited set of versions which are currently supported by both individually by the product authors, and as a collection by higher-level software layers.
So Joomla will have a set of major and minor versions currently supported, and these versions will, in turn, only support certain other versions of PHP and MySQL.
And similarly, Fabrik will support only certain versions of PHP, MySQL and Joomla.
Additionally, your web hosting supplier may have its own limitations on versions of PHP and MySQL that they support, and sometimes they change versions without letting you know first - if your software is not ready for the new version you may find yourself scrabbling to get your web site working again on other software versions which you cannot get help for. Surely it is better to stay ahead of these problems by keeping up to date.
And to complicate things still further, a lot of Joomla and Fabrik functionality is based on other Open Source components that have their own supported versions and support timescales.
2. Security
Regardless of supported versions, there may be other pressing reasons to keep your software up to date, most notably security. Joomla and Fabrik have both had security issues in the past that have resulted in web-sites being hijacked, and staying up to date is the best way to avoid security issues impacting your own site.
Joomla security issues are actually fairly common, even though most of them are minor - see

3. Functionality, reliability and Performance
Regardless of the above, you may well want to keep your site software up to date to take advantage of functional, reliability or
Performance improvements from the most recent versions of software.
