Re: KAV/KIS 2013 Beta Update on current status: Build 220.127.116.1170 has been set as Technical Release (code frozen, all changes are done via patches on update servers). The 18.104.22.16870 install package provided on devbuilds is from beta branch, not from release branch. Wait for it to appear on official product update servers if you want to install a release/non-beta 22.214.171.12470 build.
