Tvheadend version with ca0 support for Synology wanted

Dear all, maybe somebody could help me. I am running a Synology DS415play and tvheadend (currently 4.1.2409 from dierkse) on it. For dvb input I am using a TT CT 3650 CI dvb-c box. This is running well.

Now I want to use my alpha crypt light module with the TT-box and tvheadend. As far as I know, there should be a configuration part in the dvv-input section which supports the configuration of CI modules. In the Version I am running, this section misses :-(

Maybe somebody could help me and provide a link to a tvheadend version where CI is supported. For my DS415 I appreciate evansport-packages. Many thanks in advance! Any other hint or tipp which helps is also warmly welcomed :-) Thank you!
