The Sven Co-op Website offers a new version 4.7 that was released on Christmas for this Half-Life modification as support for this old-school shooter mod continues into a third decade (or second century if you want more drama, or second millennium if you want full-on hype). They say they are not running out of steam, as plans for version 5.0 are already on the boards, which they say will represent a "major stepping stone for the mod." Here's word on the new release: "This release includes fixes and improvements to Half-Life co-op, Opposing Force co-op, They Hunger Co-op, etc., as well as Linux server support, new and updated maps, new features, fixes etc."
