-current: The development branch. Every six months,-currentis tagged and becomes the next-release. -
-stable: The-releasebranch, plus patches found on the OpenBSD errata page. Very important fixes are backported to the supported-stablebranches.
OpenBSD publishes announcements and security advisories on the announcement mailing list. There’s an RSS feed for errata as well.
