After its release, Unicorn made some good impact in the security community and quickly established itself as the foundation of <a target=\"_blank\" href=\"https://www.unicorn-engine.org/showcase\">various innovative work</a>. More than 6 years passed, it is time to make a major step forward with Unicorn2!</p>\n<p>Based on Qemu 5, we built Unicorn2 from scratch, with a lot of optimization on performance &amp; code size. While still maintaining backward compatibility with the current version, Unicorn2 supports the latest instruction set of all important CPU architectures, including X86, Arm, Aarch64, Mips, Sparc &amp; M68k. Going further, we also added 2 highly-demanded architectures in <strong>PowerPC</strong> &amp; <strong>RISCV</strong>.</p>\n<p>The source code of Unicorn2 is now available at <a target=\"_blank\" href=\"https://github.com/unicorn-engine/unicorn/tree/dev\">dev branch</a> on our Github repo.
