squid-2.5.STABLE11.tgz

[Joe S]

I'm running OpenBSD 3.7-STABLE. I'm trying to find an updated package: 
squid-2.5.STABLE11-transparent.tgz

I checked /pub/OpenBSD/3.7/packages/i386 of a few FTP servers and only 
found squid-2.5.STABLE11.tgz.

I noticed that squid-2.5.STABLE11-transparent.tgz is available for 3.6, 
but not 3.7. When can we expect a new package?

Where can I find more information about security updates for packages, 
other than checking the FTP server?
