-------------------------------

Highlights

- macOS arm64 no longer provides binary wheels due to a feature missing from Github Action runners.
- py3.8 support is brought back, python2 wheels are built and test as well and we migrate to cibuildwheel! Antelox
- Several polish to python bindings and implement new API. elicn droe
- Revert previous break changes that return UC_ERR_ARG for non-existing registers. Now this prints a warning. We urge all users relying on this behavior to fix code as soon as possible.
- Fix several segment faults, including a few long-standing random segfault issues.
- Revive previous unicorn 1 test suite and related refactoring. elicn Antelox
- Optimize memory handling and notdirty writes for faster memory access and snapshots, especially useful for fuzzing. PhilippTakacs

- Support UC_TCG_OP_FLAG_CMP for ARM dotCirill
- An alternative tag prefixed with "v" is added for golang compatibility.

Fix & Improvements

- Implement UC_ARM64_REG_WSP
- Several fixes on arm64 macos tbodt
- reg_read_batch and reg_write_batch hsa1as

As usual, thanks to all contributors and sorry if I missed your name here (please tell me wtdcode !).

Lastly and personally, I would like to express my big thanks to Antelox elicn and PhilippTakacs for spending lots of time improving Unicorn Engine. Also, there are a few big pull requests adding new architectures (RH850, TCI, LoongArch64, AVR) and I will actively push them to 2.2.0.

-------------------------------

This is a small release to fix a few urgent issues.

- Remove pkg_resources usage
- Fix wheels distribution for x86_64 macos
- Fix redundant wheel hacks
- Support musllinux distribution

-------------------------------

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
