Highlights

• The SPARC module was updated to LLVM-18 (please see the Release Guide for details).
• Python bindings now use ABI3 wheels.
• Added support for Apple's proprietary AArch64 instructions.
• Instructions that can be decoded but are invalid for other reasons are now marked as such (https://github.com/capstone-engine/capstone/pull/2707).

Note about published Python Wheels

The Alpha5 Python packages on PyPi were published by accident with commit [5d989a] of PR https://github.com/capstone-engine/capstone/pull/2765. The build is equivalent to tag 6.0.0-Alpha5, except for the additions to Changelog.md. Because Changelog.md is not part of the distributed Python wheels, we didn't republish the packages. Sorry for any inconvenience.
