The signatures:

Each tarball is signed by Vincent Lefèvre. This can be verified using
the DSA key ID 980C197698C3739D; this key can be retrieved with:

  gpg --recv-keys 980C197698C3739D

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

  07F3 DBBE CC1A 3960 5078  094D 980C 1976 98C3 739D

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

Changes from version 3.1.5 to version 3.1.6:
- Improved MPFR manual.
- Bug fixes (see <> and ChangeLog file).
- Autotools: Under Linux, make sure that the old dtags (when supported)
  are used if LD_LIBRARY_PATH is defined; otherwise "make check" would
  check an installed, compatible MPFR library found in LD_LIBRARY_PATH
  instead of the one that has been built with "make".

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

If no problems are found, GNU MPFR 3.1.6 should be released
around 2017-09-07.
