Comodo FW 5.12 on win7 64 still able to offer great protection ?

Hello, I’m still using Comodo FW 5.12 with D+ on win7 64,

I can stay with 5.12 because there’s no security risk with it ? or new version is able to block dangerous things that version 5.12 can’t ?

If I’not secure anymmore,
can someone give me some exemple that 7.0 block but not 5.12 ?

Thanks, greeatings.

I use CIS 5.10 and not have worry for years.
