- Dimensions now depend on units (base or coherent units are provided in a class template)
- Quantity gets a Dimension template parameter again (as unit does not provide information about its dimension anymore)
- Spaceship operator support added
- Added official CGS system support
- Added official data information system support
- Repository file tree cleanup
- ratio refactored to contain Exp template parameter (thanks a lot @oschonrock!)
- SI fundamental constants added
- q_ prefix applied to all the UDLs (thanks @kwikius)
- unknown_unit renamed to unknown_coherent_unit
- Project documentation greatly extended and switched to Sphinx
- A few more usage examples added
- ASCII-only output support added (thanks @yasamoka)
- Representation values formatting extended (thanks @rbrugo)
- Output streams formatting support added
- Linear algebra from std::experimental::math support added
- Named SI units and their dimensions added (thanks @rbrugo
- libfmt updated to 6.2.0
- Added absolute functions and epsilon to math.h (thanks @mikeford3)
- Added a lot of prefixes to named units and introduced alias_unit (thanks @yasamoka)
- Linking with Conan targets only when they exists (#98)
- All physical dimensions and units put into physical namespace
- CMake improvements
- Velocity renamed to speed
Many thanks to GitHub users @oschonrock, @kwikius, and @i-ky for their support in drafting a new library design.
