    # Release v0.12.0

## Breaking Changes

- This library requires C++23 from this version.
- Removed concepts in `base` module that are implemented by concepts in C++ standard library.
- Separated `constants` module into existing `base` and `functions` module.
  - Constants are in `base` module.
  - Mathematical functions are in `functions` module and they are updated for use in both compile time and runtime (for runtime, they use functions in C++ standard library).

  - Asynchronous logging (see documentation of logging configuration).
- `multi_double` module
  - Added some mathematical functions for `num_collect::multi_double::quad` class.
