Its now a long time i use squidguard, but the last days i see at the package-manager "1.3_1 pkg v.1.9", while pkg_info shows "squidGuard-1.4_2". I think its a cosmetic error, but package-manager made "booh" about the wrong version. (box shown in grey, not white when actual or red when outdated)
Nothing was done. Maybe just not properly describe version
pfSense 1.2.3 - SG 1.3_1
pfSense 2.0 - SG 1.4_2
And the file http://www.pfsense.org/packages/config/squidGuard/squidguard.xml contains 1.3_1 version.
This is a bug in the version descriptions.
