• An Openbsd-release is issued twice each year, and never changes.
• Errata patches are published for security issues, or for stability or operational issues which are considered to have large impact on the user community. For 6.2, there has been one errata patch published to date, specific to OpenBSD/amd64.
• The syspatch(8) tool applies binary versions of the errata patches distributed for the amd64 and i386 architectures. The architecture set may change in the future.
• The OpenBSD-stable branch is -release, plus errata patches, plus any additional patches that have been developed for the -release but do not warrant publishing as errata. There's been one patch of this type added to 6.2-stable to date.
• The ports tree receives -stable patches also, primarily to address CVEs. There have been several of these patches of the ports tree to date. The project does not package these -stable ports, as it has insufficient resources to do so. M:Tier does provide packages of these -stable ports, as a service. And of course, sufficiently skilled users may build packages from these ports themselves.
• OpenBSD-current is the development branch, where the next -release is already being developed.
