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:

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
