0.5.1

Release Notes

Upgrading from (0.5.0)

This patch release contains only bug fixes, and should present no
difficulties when upgrading from 0.5.0.

User-facing library changes

Issues fixed:

• Fixed ambiguous two-parameter constructor for Quantity and
  QuantityPoint (#525)
• Improved efficiency (fewer assembly instructions) of mean()
  implementation (#526)
• Make N in mag<N>() a std::uintmax_t, not size_t, improving
  compatibility on architectures where size_t is 32 bits (#542)
• Fix various compiler errors on GCC 5.3 (#548)
• Support constexpr use of data_in() for Quantity and
  QuantityPoint (#556)

Future-proofing releases

• 🚀 0.5.1-future-122: release covering #122

  • This commit opts-in all of our "explicit rep" APIs to the conversion
    safety checks. To fix build errors, read the error to see what risk
    set the library has flagged. Then, refer to our conversion risk
    guide
    https://aurora-opensource.github.io/au/0.5.1/troubleshooting/#risk-too-high
    and carefully consider how to handle this specific instance.

• 🚀 0.5.1-future-185: release covering #185

  • This commit makes it so that Quantity operations always return a
    Quantity, never a raw number. To fix build errors, wrap the
    Quantity operation inside of a call to as_raw_number().

• 🚀 0.5.1-future-429: release covering #429

  • This commit deletes the UnitAvoidance construct. To fix build
    errors, instead of specializing ::au::detail::UnitAvoidance,
    specialize ::au::UnitOrderTiebreaker.

• 🚀 0.5.1-future-481: release covering #481

  • This commit removes all APIs with the word "coerce" in their name.
    To fix build errors, first, delete the coerce_ part of the name.
    Then, if you get a compiler error, read the error to see what risk
    set the library has flagged, and refer to our conversion risk guide
    https://aurora-opensource.github.io/au/0.5.1/troubleshooting/#risk-too-high
    to see how to handle this specific instance.
