Even though it was known by most of FreeBSD users that the 9.0 release of the best BSD operating system will reach EOL (End-Of-Life) on March 31, 2013, we feel obliged to announce users that FreeBSD 9.0 is no longer supported.
Originally released on January 10, 2012, FreeBSD 9.0 was a short-term supported release (one year), as opposed to the FreeBSD 8.3 release, which is still supported until April 30, 2014.
Since November 2012, FreeBSD 9.0 users received a warning message when they tried to update their system, saying "WARNING: FreeBSD 9.0-RELEASE-p3 is approaching its End-of-Life date. It is strongly recommended that you upgrade to a newer release within the next 2 months."
Those of you who want to upgrade to a newer release, can download FreeBSD 9.1 right now from Softpedia, which is supported with security updates until December 31, 2014.
