AFAIK, no one is looking after the module repository on an active basis here at xoops.org.
Two other sites have been set up as community sites
xoopsaddons.org which was supposed to be a new module repository but is currently offline. xoopsmoddev.org whic is up and running and is trying to be the new home for module developers.
You might try asking this question at xoopsinfo.com
Xoops 2.0.17 and 2.2.5 are currently under review prior to release. As for the 'new system', you'd have to ask phppp about that.
