From: Brent Cook <busterb () gmail ! com>
We have released LibreSSL 4.0.0, which will be arriving in the
LibreSSL directory of your local OpenBSD mirror soon. This is the
first stable release for the 4.0.x branch, also available with OpenBSD 7.6
It includes the following change from LibreSSL 3.9.2:
* Portable changes
- Added initial Emscripten support in CMake builds.
- Removed timegm() compatibility layer since all uses were replaced
with OPENSSL_timegm(). Cleaned up the corresponding test harness.
- The mips32 platform is no longer actively supported.
- Fixed Windows support for dates beyond 2038.
