- [PR#614](https://github.com/biojppm/rapidyaml/pull/614) improve base64 serialization facilities:
  ```c++
  std::string decoded;
  tree["node"] >> fmt::base64(decoded); // now works!
  // also can now obtain the size explicitly:
  substr buf = ...;
  size_t required = 0;
  tree["node"] >> fmt::base64(buf, &required);
  ```
- Update c4core to [0.4.0](https://github.com/biojppm/c4core/releases/tag/v0.4.0).
