 # CHANGELOG
 
+## 2.3.0
+
+1. Rename all macros `COPP_*` to `LIBCOPP_*`
+2. Make all macros in compile_optimize.h and explicit_declare. standalone from atframework
+3. Merge boost.fcontext 1.87
+4. Remove `LIBCOPP_MACRO_HAS_EXCEPTION`
+5. Add nostd type_traits and `strong_rc_ptr` for non thread-safety smart pointer
+6. Remove `LIBCOPP_DISABLE_ATOMIC_LOCK`, `LIBCOPP_LOCK_DISABLE_THIS_MT` and `LIBCOPP_LOCK_DISABLE_MT`. We use the only one option `LIBCOPP_ENABLE_MULTI_THREAD` now.
+7. Allow to disable multi-thread support for stack pool and C++20 coroutine to reduce cache miss.
+8. We allow use lightweight callback or channel mode(without callback) for C++20 coroutine generator.
+9. Add `copp::make_channel<T>()` to create channel receiver and sender for easier usage.
+
 ## 2.2.0
 
 1. Merge boost.fcontext 1.81.0
