ImpressCMS 1.3.2 Final (22 April 2012)
What s New?
Faster & Lower Memory requirements
The refactoring in the ImpressCMS 1.3 release has resulted in major improvements: less memory use, speedier page loads and less SQL queries per page, making it the fastest and nimblest ImpressCMS to date.
Fully PHP 5.3 compatible
The structure of the code has seen a major overhaul, in order to comply with the current best practices for PHP5. This makes the code easier to write, and easier to maintain.
Facilitated module development
By using the automatic inclusion of required files, module developers can think about improving their module, and not about handling file administration.
Module updates
Many modules have received compatibility updates to work with this release. Other modules have been written specifically to take advantage of the improved codebase of version 1.3.
