# Release notes
- 0.5.0 WIP
- Major refactoring and rewrite of the library
- Units are now independent from dimensions
- 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)
- 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 extended and switched to Sphinx
- A few more usage examples added
- ...
Many thanks to GitHub users @oschonrock and @kwikius for their support in drafting
a new library design.
- 0.4.0 Nov 17, 2019
- Support for derived dimensions in `exp` added
- Added `pow()` and `sqrt()` operations on quantities
- `units` removed from a `std::experimental` namespace

- From now on base dimensions should inherit from `base_dimension` class template
- Added unit symbols definitions to `base_dimension` and derived units
- Added support for `operator<<` on `quantity`
- `fmt` support added
- Derived unit factory helpers refactored
- Refactored the way prefixed units are defined
- 0.3.1 Sep 18, 2019

- 0.3.0 Sep 16, 2019 (CppCon 2019 design)
- The design as described on CppCon 2019 talk (<https://youtu.be/0YW6yxkdhlU>)
- Applied the feedback from the Cologne evening session
- `upcasting_traits` renamed to `downcasting_traits`
- `Dimension` template parameter removed from quantity
- `units` moved to a `std::experimental` namespace
- Leading underscore prefix removed from UDLs
- Added a few more derived dimensions
- `meter` renamed to `metre`
- Missing `operator*` added
- Predefined dimensions moved to a dedicated directory
- `dimension_` prefix removed from names of derived dimensions
- cmcstl2 library updated to 2019.09.19
- `base_dimension` is a value provided as `const&` to the `exp` type
- integrated with Compiler Explorer
- gsl-lite dependency removed
- Fractional dimension exponents support added
- `QuantityOf` concept introduced
- `quantity_cast<U, Rep>()` support added
- 0.2.0 July 18, 2019 (C++Now 2019 design)
- The design as described on C++Now 2019 talk (<https://youtu.be/wKchCktZPHU>)
- Added C++20 features supported by gcc-9.1 (`std::remove_cvref_t`, down with typename, `std::type_identity`)
- Compile-time performance optimizations (`type_list`, `common_ratio`, `ratio`, `conditional_t`)
- 0.1.0 May 18, 2019
