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 <https://www.vinc17.net/pgp.html>.
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 <https://www.mpfr.org/mpfr-4.2.0/#fixed> 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.

Please send success and failure reports with "./config.guess" output
to <mpfr@inria.fr>.

If no problems are found, GNU MPFR 4.2.1 should be released on 2023-08-22.
