Sorry for the delay between the first release candidate and the
second one. All the problems with the RC1 should now be fixed.

Changes from version 2.4.1 to version 2.4.2:
- Security fix in formatted output functions (buffer overflow).
- Formatted output functions: 6 is now the default value for
  empty precision field with %Rf.
- Better portability of configure script.
- Detection of intmax_t and uintmax_t types.
- Improved documentation: mpfr_get_z_exp, mpfr_strtofr, mpfr_get_str and
  formatted output functions.
- Improved message in case of assertion failure.
- Test coverage: 97.0% lines of code.
- Updated tcmp_ld test to really test the long double.
- Some documentation files are installed in $docdir.
- Removed mpfr_init_cache (unused and undocumented function).
- Bug fixes.

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

If no problems are found, GNU MPFR 2.4.2 should be released
around 2009-11-30.
