On June 30th, FreeBSD 7.2 will reach its End of Life and will no longer be supported by the FreeBSD Security Team. Users of this release are strongly encouraged to upgrade to FreeBSD 7.3 before that date; FreeBSD 7.3 will be supported until the end of March 2012. Please note that since FreeBSD 7.1 has been designated for ‘Extended’ support, it will continue to be supported until the end of January 2011, i.e., FreeBSD 7.1 will be supported longer than FreeBSD 7.2.
The End of Life date for FreeBSD 7.2 was originally announced as May 31, but was delayed by one month in accordance with Security Team policy in order to allow a 3 month window between the release of FreeBSD 7.3 and the End of Life of FreeBSD 7.2 to allow time for systems to be upgraded.
The freebsd-update(8) utility can be used to upgrade i386 and amd64 systems from 7.2-RELEASE (or 7.2-RELEASE-pX for some X) to 7.3-RELEASE using binary updates (i.e., without compiling from source) as described in the 7.3-RELEASE announcement; given an adequate internet connection, this process usually takes 15 minutes or less.
