4.2.1
patches 1 to 12 from 4.2.0 have been built in to 4.2.1
Other bugs fixed in the 4.2 branch for the MPFR 4.2.1 release:
The + and space flags were ignored on NaN and Inf. While this was loosely
documented as such (without an explicit mention of these flags), the MPFR
manual also says that the flags have the same meaning as for the standard
printf function. So this was contradictory and regarded as a bug. Behaving
like the ISO C standard should give less surprise, and this is probably
what is expected (better for alignment purpose). See discussion (only for
NaN and the + flag at that time).
Corresponding changeset in the 4.2 branch: 3761bee3c.
Huge negative exponents can trigger integer overflows in mpfr_strtofr,
meaning undefined behavior. Two bugs have been identified: 1, 2. In
practice, the consequences may be incorrect results. But for the first bug,
it has been seen that a GCC optimization makes it invisible. There are
other issues with the code for huge exponents, but it is not clear whether
the problematic cases can occur in the context of mpfr_strtofr; such
potential bugs are not fixed yet.
Corresponding changesets in the 4.2 branch: 261d3852b (tests), 06e7b6bc1
(bug fixes).

Changes from versions 4.1.1 to version 4.2.0
Binary compatible with MPFR 4.0.* and 4.1.*, though some minor changes in
the behavior of the formatted output functions may be visible, regarded as
underspecified behavior or bug fixes (see below).
New functions mpfr_cosu, mpfr_sinu, mpfr_tanu, mpfr_acosu, mpfr_asinu,
mpfr_atanu and mpfr_atan2u.
New functions mpfr_cospi, mpfr_sinpi, mpfr_tanpi, mpfr_acospi, mpfr_asinpi,
mpfr_atanpi and mpfr_atan2pi.
New functions mpfr_log2p1, mpfr_log10p1, mpfr_exp2m1, mpfr_exp10m1 and
mpfr_compound_si.
New functions mpfr_fmod_ui, mpfr_powr, mpfr_pown, mpfr_pow_uj, mpfr_pow_sj
and mpfr_rootn_si (mpfr_pown is actually a macro defined as an alias for
mpfr_pow_sj).
Bug fixes.
In particular, for the formatted output functions (mpfr_printf, etc.),
the case where the precision consists only of a period has been fixed
to be like .0 as specified in the ISO C standard, and the manual has
been corrected and clarified.
The macros of the custom interface have also been fixed: they now behave
like functions (except a minor limitation for mpfr_custom_init_set).
