The FreeBSD Security Officer provides security advisories for the -following releases of FreeBSD:
+The FreeBSD Security Officer provides security advisories for +several branches of FreeBSD development. These are the -STABLE +Branches and the Security Branches. (Advisories are not +issued for the -CURRENT Branch.)
There is usually only a single -STABLE branch, although +during the transition from one major development line to another +(such as from FreeBSD 4.x to 5.x), there is a time span in which +there are two -STABLE branches. The -STABLE branch tags have names +like RELENG_4. The corresponding builds have names like +FreeBSD 4.6-STABLE.
Each FreeBSD Release has an associated Security Branch. +The Security Branch tags have names like RELENG_4_6. +The corresponding builds have names like FreeBSD +4.6-RELEASE-p7.
Each branch is supported by the Security Officer for a limited time +only, typically through 12 months after the release. The estimated +lifetimes of the currently supported branches are given below. The +Estimated EoL (end-of-life) column gives the earliest date on +which that branch is likely to be dropped. Please note that these dates +may be extended into the future, but only extenuating circumstances +would lead to a branch's support being dropped earlier than the date +listed.
+ +| Branch | +Release | +Estimated EoL | +
|---|---|---|
| RELENG_4 | +n/a | +December 31, 2003 | +
| RELENG_4_6 | +4.6-RELEASE | +May 31, 2003 | +
| RELENG_4_7 | +4.7-RELEASE | +September 30, 2003 | +
| RELENG_5_0 | +5.0-RELEASE | +June 30, 2003 | +
Older releases are not maintained and users are strongly encouraged to upgrade to one of the supported releases mentioned above.
