Flint 2.8.4 Released

[Bill Hart]

Hi all,

I just tagged Flint-2.8.4. This is a critical bug fix release and so
we strongly recommend upgrading.

* Fix a serious bug in fmpz_mod_poly_xgcd for polynomials of large length
* Fix an assertion failure in fmpz_mat_solve_fflu (only relevant if
asserts enabled)
* Fix some bugs on 32 bit machines
* Work around a compiler bug on Apple M1
* Fix bug in nmod_mpoly_factor (returned 0 for some factorisations)
* Fix some documentation build errors and some doc formatting issues

Please note that the C++ wrapper is now considered unmaintained. We
will keep it compiling in its current state, but will not be wrapping
additional flint functions.

If any C++ developers would like to take over maintenance, we estimate
it would be about 3-4 months of effort full time to wrap the remaining
flint functions in C++ for a VERY experienced C++ developer. Replacing
the old metaprogramming wrapper with a new one using more modern C++
features would be about 4-6 months full time work for an experienced
C++ developer.

If you would like to volunteer, but not be paid for your effort,
please let us know [1].

Bill.
