Version v2.1.0

It has been a while since the last release, and 2.1.0 brings several exciting features. Below is the changelog from the latest to the oldest (though not strictly).

Highlights

• Revive QEMU logs, now we have -DUNICORN_LOGGING=yes to enable all qemu logs. @BitMaskMixer
• Faster (up to 40x) write performance by not always doing store_helper and cleaning page locks. @tunz @boborjan2
• Brand new python bindings, with strongly typed and many improvements. @elicn
• Fix to a long-standing MinGW random segfault bug.
• We bring python2 compatibility back.
• We now fully support M1, both building and a pre-built wheel.
• We support snapshot memory now, with a very low overhead copy-on-write fashion. @PhilippTakacs
• An option to bypass MMU is also added, check our FAQ. @PhilippTakacs
• A brand new (and modern) java bindings. We are also working to publish it to maven. @nneonneo
• We have zig integrated. @kassane @atipls
• Now Unicorn no longer allocates 2GB memory for every instance. The memory will be only committed once used and the upper limit can be adjusted with uc_ctl.
• New DotNet binding, with published to both Github and Nuget. @TSRBerry
• The release will attach all binaries, thanks to @marameref
