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
