Fwd: Announcing libffi 3.4.2

[Anthony Green]

I release 3.4.2 yesterday!  Thanks to everyone who contributed!

To be honest, with the CI infrastructure falling apart in the last few
weeks, I'm guessing we may need to make fast-following 3.4.x releases,
but we'll see.  Job number one is really moving as much CI to github
actions as quickly as possible.

I know that various Linux distro build systems are very active right
now, and I'm hopeful that we'll see this in wide usage very soon.

Thanks again,

AG

I'm very pleased to announce the release of libffi version 3.4.2, which
you are free to download here:

  https://github.com/libffi/libffi/releases/download/v3.4.2/libffi-3.4.2.tar.gz

Here are some of the highlights of this release:

    3.4.2 Jun-28-21
        Add static trampoline support for Linux on x86_64 and ARM64.
        Add support for Alibaba's CSKY architecture.
        Add support for Kalray's KVX architecture.
        Add support for Intel Control-flow Enforcement Technology (CET).
        Add support for ARM Pointer Authentication (PA).
        Fix 32-bit PPC regression.
        Fix MIPS soft-float problem.
        Enable tmpdir override with the $LIBFFI_TMPDIR environment variable.
        Enable compatibility with MSVC runtime stack checking.
        Reject float and small integer argument in ffi_prep_cif_var().
          Callers must promote these types themselves.

Of particular note is Madhavan Venkataraman's static trampoline work,
as it can eliminate
the need for writeable/executable memory under certain conditions.

As usual, many thanks to all of the contributors!
