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

You should check that the key fingerprint matches.

Changes from version 4.0.1 to version 4.0.2:
- Corrected minimal GMP version in the INSTALL file and the MPFR manual.
- Shared caches: cleanup; really detect lock failures (abort in this case).
- Improved MPFR manual. In particular, corrected/completed the
  mpfr_get_str description in order to follow the historical behavior
  and GMP's mpf_get_str function.
- Bug fixes (see ChangeLog file).

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

If no problems are found, GNU MPFR 4.0.2 should be released
around 2019-01-31.
