Upgrade From

ImpressCMS 2.0.0 Alpha5 Alpha 07 April 2015 in the package zip tar.gz N/A

What else do I need?

This release of ImpressCMS officially supports PHP 5.4.x. With this release, we are moving farther into supporting stable versions of PHP5.  The current stable releases of PHP are 5.6.7, 5.5.23 and 5.4.39.

PHP 5.4.x should work in most cases as well, althought there might be a few issues in PHP strict mode.

  • PHP: 5.4.0+ (5.3 is NOT recommended, and 5.5+ is now officially supported and recommended)
  • MySQL: MySQL server 4.1.0+ - With UTF-8 Support
  • Web server: Any server supporting the required PHP version (Apache highly recommended). 
  • Special characters require UTF-8 support from hosting providers.
  • 16MB PHP Memory
