Version 2.4 of the GNU C Library is now available for download at:

   http://ftp.gnu.org/gnu/glibc/
   ftp://ftp.gnu.org/gnu/glibc/
   ftp://sources.redhat.com/pub/glibc/releases/

Please see http://www.gnu.org/order/ftp.html and
http://sources.redhat.com/mirrors.html for mirror sites around the world.

Version 2.4 is the first release after a long period of development, and
introduces changes to the API and a new ABI for all configurations.  The
NEWS file in the distribution lists major additions, and there are many
smaller changes along with innumerable bug fixes.  This code has been
tested and deployed in new production systems, but should still be
considered somewhat experimental.  The stable 2.3 release series
continues to be maintained, and implements a widely-deployed ABI.
Version 2.3.6 is available, and we will release 2.3.7 with more bug fixes.

Once you install version 2.4, most program binaries you compile will not
be able to run on older installations based on 2.3.6 or earlier versions.
Existing dynamically-linked program binaries built using older glibc
versions should continue to work if they make proper use of the library
interfaces as specified.

While the code in this release has received substantial testing and is
going into new production systems, we are already aware of a few issues
and have a backlog of problem reports awaiting investigation.  We believe
this release marks a point of decent stability and substantial improvement
over version 2.3, and its ABI will remain stable for later 2.4 releases.
We hope that making this release now will lead to more strenuous testing.
We anticipate a 2.4.1 release in the not too distant future to tie up
loose ends and fold in more fixes and improvements made after the initial
deployments of systems based on the 2.4 ABI.

Be advised that updating the C library is no trivial task and it is very
easy to damage one's system.  Unless you are participating in the
development and maintenance of the C library, you should use a binary
distribution instead.  The code in this release has already been built
and tested by maintainers of binary distributions basing their systems
on it.  If you are not already using a system based on the version 2.4
ABI, then you may wreak havoc by attempting to install this version.

We recommend using GCC 4.1 to build this version of the GNU C Library.
For the S/390 and 32-bit PowerPC architectures, GCC 4.1 is required.
For other architectures, GCC 3.4 or later will work but 4.0 and 4.1 are better.
