We added a feature to permit usage of search engine friendly URLs (SEF URLs). Page addresses are transformed automatically and do not have to be corrected in templates. To guarantee a reverse compatibility, it is recommended to use addresses in their classic form in the scripts, for example: /?param1=1 and etc.
Transformation of addresses is reversible. Usual address and that very address transformed to SEF URL always lead to the same page, no matter, whether usage of SEF URL is enabled or disabled.
Now, we are testing this application at the demo site.
