Those of you running the FreeBSD 4.x tree will be happy to know that FreeBSD 4.11 is now available. The release announcement calls 4.11 "the latest release of the FreeBSD Legacy development branch" and states the following:
"FreeBSD 4.11 will become the first 'Errata Branch.' In addition to Security fixes other well-tested fixes to basic functionality will be committed to the RELENG_4_11 branch after the release... This is expected to be the last release from the RELENG_4 branch."
I am no longer running any 4.x systems and have migrated everything to 5.3.
