• Version 0.5 is released. Except for various performance improvements, including spinlock, context switch, and new run queue for coroutine scheduling, we have re-implemented the HTTP module so that there is no boost dependency anymore.
• Version 0.4 has come, bringing us these three major features:
  1. Support coroutine local variables. Similar to the C++11 thread_local keyword. See doc.
  2. Support running on macOS platform, both Intel x86_64 and Apple M1 included.
  3. Support LLVM Clang/Apple Clang/GCC compilers.
• Photon 0.3 was released on 2 Sep 2022. Except for bug fixes and improvements, a new photon_std namespace is added. Developers can search for std::thread, std::mutex in their own projects, and replace them all into the equivalents of photon_std::<xxx>. It's a quick way to transform thread-based programs to coroutine-based ones.
• Photon 0.2 was released on 28 Jul 2022. This release was mainly focused on network socket, security context and multi-vcpu support. We re-worked the WorkPool so it's more friendly now to write multi-vcpu programs.
• Made the first tag on 27 Jul 2022. Fix the compatibility for ARM CPU. Throughly compared the TCP echo server performance with other libs.
