Let PHP handle the session garbage collection to have the same behaviour as file based sessions regarding session life time
Increase session ID field (sesskey) to varchar(128) to better support session.hash_function and session.hash_bits_per_character
Fix issues with missing order total modules
If a module has been installed and the module files were deleted, the parameters would still exist in the database. If the module files were copied again to the modules directory, installing the module would introduce duplicate module parameters, so when installing a module, check if it has been installed previously and call its remove() function before installing the module again.

Proposal for content modules
Minor optimization - disable the module in the constructor if the conditions are not met. This prevents execute() being called at all.
Reverse previous change
Introduce template page modules - if a page module exists for a template block (sharing the same name), automatically load the page module before calling the template block modules.
test modules
add getBlocks() to checkout success page
rename modules
Don't integrate content modules into the template (cfgm_content->template_integration) so content modules are only loaded on demand. Add content functions to the template class to separate the content (on demand) from blocks (global).
modularize login page
Introduce Log In with PayPal
Move content modules to own group subdirectories
Replace standard module configuration page with a dedicated content module page
