Key improvements for release 0.9.0: Faster system calls and context switching. Improved virtual and physical memory management, including the significantly faster p2buddy memory allocator. Improved filesystem performance. Self-hosting improvements. Userspace ABI improvements, towards the long-term goal of a stable ABI. VirtIO drivers for better performance in virtual machines. Virtualized TSC gives a massive boost to context switching speed in virtual machines. The Unix path format replaced the previous URI format used in our system interfaces, improving compatibility with POSIX/Linux libraries and programs. Relibc (our C library implementation) is almost 100% Rust (excluding libm) and much more complete. Improvements to the bootloader for more hardware compatibility. Significant progress on the ARM64 (Aarch64) support, including partial support for Raspberry Pi 3B+. Contain (Redox's sandbox driver) has been expanded and is available as a demo (desktop-contain.toml). The first HTTP web server was ported (Simple HTTP Server).
