Version 2.4.0 - 2022-04-05
New Features:
- Construct a compound type from an already existing hid (BlueBrain#469). Thanks to Maximilian Nöthe.
- Add support for long double (BlueBrain#494)
- Add support for H5Pset_libver_bounds and H5Pset_meta_block_size support (BlueBrain#500)
- New interface to select complex hyperslabs, irregular hyperslabs are limited to/from 1D array (BlueBrain#538 and BlueBrain#545)

Improvements:
- Use inline where it is needed, otherwise some code can lead to "multiple definition" (BlueBrain#516). Thanks to Chris Byrohl.
- Use Catch2 inside of boost for tests, this way there is less dependencies (BlueBrain#521)
- CI now run with more external librairies (boost, eige, xtensor, xtl) (BlueBrain#536)

Bug Fixes:
- Better support of const types (BlueBrain#460). Thanks to Philip Deegan.
- Vector of size zero was previously lead to UB (BlueBrain#502). Thanks to Haoran Ni.
- Use H5T_NATIVE_SCHAR instead of H5T_NATIVE_CHAR for "signed char" (BlueBrain#518)
