FreeBSD 5.1 has been released. This is mostly a technology release, focussed primarily on extending FreeBSD's multiprocessor and application-level threading support. Although many bugs have been fixed since the 5.0 release [story], FreeBSD 5.1 might not be suitable for all users yet, Scott Long of the Release Engineering Team warns in the announcement. If you require the absolute stability FreeBSD is known for, you can always run the latest 4.x release. The release is dedicated to the memory of Alan Eldridge, a talented and dedicated member of the KDE On FreeBSD team.
From: Scott Long (scottl at FreeBSD dot org) To: freebsd-announce at FreeBSD dot org Subject: [FreeBSD-Announce] FreeBSD 5.1 Released! Date: Mon, 9 Jun 2003 09:36:57 -0700 (PDT) It is my great privilege and pleasure to announce the availability of FreeBSD 5.1-RELEASE. This release continues FreeBSD on the path of advanced multiprocessor and application thread support and includes many improved and widely-sought features: * Experimental 1:1 and M:N thread libraries provide kernel support for efficient application multithreading. * Support for Physical Address Extensions enables Pentium Pro and higher CPUs to access up to 64GB of RAM. * Experimental Name Service Switch infrastructure allows enterprises to seamlessly integrate with LDAP and Active Directory services. * Enhanced "jail" management, allowing one server to provide many different "virtual machines" with reduced administrator workload. * New device drivers include support for IBM/Adaptec ServeRAID controllers, expanded support for USB 2.0 and USB Ethernet adapters, and Promise Serial ATA controllers. * Experimental support for the amd64 platform allows FreeBSD to run on single processor AMD Opteron systems. Although stability is greatly improved and many bugs have been fixed, FreeBSD 5.1 might not be suitable for all users. More conservative users may prefer to continue using FreeBSD 4.X. Information on the various trade-offs involved, as well as some notes on future plans for both FreeBSD 4.X and 5.X, can be found in the Early Adopter's Guide, available here: http://www.FreeBSD.org/releases/5.1R/early-adopter.html For a complete list of new features and known problems, please see the release notes and errata list, available here: http://www.FreeBSD.org/releases/5.1R/relnotes.html http://www.FreeBSD.org/releases/5.1R/errata.html For more information about FreeBSD release engineering activities, please see: http://www.FreeBSD.org/releng/ This release is dedicated to the memory of Alan Eldridge. Alan was a talented and dedicated member of the KDE On FreeBSD team and the FreeBSD community, and his passing is mourned by all of us. For more information, please see http://freebsd.kde.org/memoriam/alane.php.
