The signatures can be verified with: gpg --verify <file.asc>
You should check that the key fingerprint matches.
Changes from version 4.2.1 to version 4.2.2:
- In order to resolve a portability issue with the _Float128 fallback to
__float128 for binary128 support (e.g. with Clang and glibc 2.41), the
prototypes of the corresponding conversion functions had to be changed,
with _Float128 replaced by mpfr_float128, where mpfr_float128 is a macro
defined as _Float128 by default. This changes neither the ABI nor the API
(except that the end user of MPFR would need to define mpfr_float128 as
the actual type for the binary128 format if this is not the standard
_Float128 type).
- Other bug fixes (see <https://www.mpfr.org/mpfr-4.2.1/#fixed> and/or the
ChangeLog file). In particular, the formatted output functions behaved
incorrectly with %c on the value 0; such a use is uncommon, but this bug
may have security implications.
- Improved MPFR manual.
- Detect the use of GMP's buggy vsnprintf replacement at configure time.
With it, the tests of "%a" will be disabled to avoid an assertion failure
in the MPFR testsuite. A warning will be displayed in the configure output
in such a case.
Also, note that due to new tests related to the fix of the formatted
output functions with %c on the value 0, failures in the tfprintf and
tsprintf tests may be observed if GMP has been built with its vsnprintf
replacement (i.e. if GMP detected at configure time that the vsnprintf
function from the C library is buggy/non-conforming). This is due to a
bug in the vsnprintf replacement from GMP 6.3.0 (official tarball) and
below. This could be observed on MS Windows and OpenBSD. To get rid of
these failures, either use a fixed version (recommended!) or build the
MPFR tests with the MPFR_TESTS_SKIP_CHECK_NULL macro defined.
See the INSTALL file for other details.
Please send success and failure reports with "./config.guess" output
to <m...@inria.fr>.
If no problems are found, GNU MPFR 4.2.2 should be released
around 2025-03-20.
