FreeBSD 5.3-RC1 available

The FreeBSD Release Engineering Team is proud to announce the
availability of FreeBSD 5.3-RC1.  It is intended for early adopters and
those wishing to help find and/or fix bugs.  This will likely be the
only Release Candidate before the final release of 5.3.  The schedule
can be found at http://www.freebsd.org/releases/5.3R/schedule.html.  Be
sure to check the "Known Issues" below as there are known problems that
are still being worked on at this time.

IMPORTANT:
BIND 9.3.0 has replaced BIND 8.x as the default name server.

IMPORTANT:
Several libraries have had their version numbers bumped in order to
maintain FreeBSD 4.x compatibility.  Any programs that rely on these
libraries should be rebuilt.  The /etc/libmap.conf facility can be
used to help this migration.  In particular, libm.so.2 should be
mapped to libm.so.3 while the migration is in progress.  The libraries
that changed are:

    libm.so.2 -> libm.so.3
    libhistory.so.4 -> libhistory.so.5
    libopie.so.2 -> libopie.so.3
    libpcap.so.2 -> libpcap.so.3
    libreadline.so.4 -> libreadline.so.5

Availability:

    For people wishing to upgrade older systems using cvsup(1) and the
    procedure described in src/UPDATING the CVS tag to use is RELENG_5
    at this point.  Note that like all RELENG_X branches this is an
    active development branch.  We do not recommend those branches for
    normal use (for normal use RELENG_X_Y branches are more appropriate,
    e.g. RELENG_4_10 is the current stable branch).
