The PHP group has made one final release of the 5.3 series; this marks the final release for the 5.3 series and contains fixes backported from 5.4 and 5.5.

We recommend that customers upgrade to 5.4 or 5.5 where possible. Our upcoming new web hosting services under Server 2012 and IIS8 will not include support for PHP 5.2 or 5.3. However our current Server 2008 / IIS 7.5 offerings will continue to support both. We also have PHP 5.6 which has not released final yet, but is offered to give customers a chance to get their websites updated to support the very latest in PHP!
If your web application uses PHP 5.3 and you’d like to upgrade, we recommend contacting the application developer to make sure that your website will function properly under a new version of PHP. Please do not upgrade your website simply because there is a newer version, always check with the developer(s) before upgrading.
Thank you for choosing ASPnix as your web hosting provider!
