5/ Rootfs and GCC/G++ toolchains Some rootfs for supported architectures are now available (users can choose to download or build them). They come along with GCC/G++ static cross toolchains to make compilation easier.

Many other features were implemented like running processes as part of groups (preparing IPC for a future release), a total rework of the threading and signals modules and tests were implemented with Google tests framework to gain stability. 🔥Feel free to contribute 🔥

🔥Introducing Arion🔥 A high-performance C++ framework for emulating executable binaries. Based on Unicorn and inspired by Qiling, Arion offers an easy-to-use interface and super low execution times making it a great ally for fuzzing or other applications. github.com/h311d1n3r/Arion

Here are some graphs comparing execution times between Arion (in blue) and Qiling (in red). In the first one, the variable is the amount of basic blocks in the target when they are all hooked and in the second one the variable is the amount of hit syscalls.

More than 120 syscalls are now implemented in Arion and a lot of hook capabilities are present. A wiki and a documentation should come soon, for the moment you can relate in the examples from Github. Plenty of features will be implemented by the future so feel free to contribute.
