GNU MPFR 4.2.1 ("fondue savoyarde", patch level 1), a C library for
multiple-precision floating-point computations with correct rounding,
is now available for download from the MPFR web site:

and from the GNU FTP site:

Thanks very much to those who sent us bug reports and/or tested the
release candidate.

The SHA1 digests:

The signatures:

Each tarball is signed by Vincent Lefèvre. This can be verified using
the GPG key ID 5831D11A0D4DB02A; this key can be retrieved with:

  gpg --recv-keys 5831D11A0D4DB02A

or by downloading it from <>.
The key fingerprint is:

  A534 BE3F 83E2 41D9 1828  0AEB 5831 D11A 0D4D B02A

The signatures can be verified with: gpg --verify <file.asc>
You should check that the key fingerprint matches.

Changes from version 4.2.0 to version 4.2.1:
- Bug fixes (see <> and/or the
  ChangeLog file).
- Improved MPFR manual.
- Configure tests: replaced the test of the link with GMP, in order to
  avoid the use of a function without a prototype (Autoconf issue), as
  this is obsolescent in ISO C. The new test should be more robust.

You can send success and failure reports to <>, and give
us the canonical system name (by running the "./config.guess" script),
the processor and the compiler version, in order to complete the
"Platforms Known to Support MPFR" section of the MPFR 4.2.1 web page.
