## What's New
* Since 0.7, Photon will use release branches to enhance the reliability of software delivery. Bugfix will be merged into a stable release at first, then to higher release versions, and finally main.
* Since version 0.6, Photon can run with a userspace TCP/IP stack on top of `DPDK`.

* How to transform `RocksDB` from multi-threads to coroutines by only 200 lines of code?

* 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](doc/thread-local.md).
  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.
