• v0.3.0 Changes

  December 26, 2017

  🚀 This release has been very long in coming, and brings a whole host of changes, the most notable being the removal of the user dependency on Typelevel Scala and the new angular units.

  Libra has it's first contributors! Thank you @DanielaSfregola and @ldrygala for your fantastic work! :tada:

  🆕 New units

  📦 Hours and days are now present in the imperial package. We also support angular units! Thanks to the work of @ldrygala, degrees, arcminues, arcseconds, gradians, radians and turns are now present in the nonsi package.

  🆕 New Typeclasses

  The following spire / algebra typeclasses have been added to Quantity

  • Eq
  • Order
  • PartialOrder
  • Signed
  • AdditiveSemigroup
  • AdditiveMonoid
  • AdditiveGroup
  • AdditiveCSemigroup
  • AdditiveCMonoid
  • AdditiveAbGroup
  • MetricSpace
  • CoordinateSpace
  • VectorSpace
  • InnerProductSpace

  These are dependent on the typeclasses of the underlying numeric type.

  🆕 New operations

  👍 Quantities now support Euclidean division with spire's /~ quotient operator

  ⬆️ Upgrades

  ⬆️ The scala versions have been upgraded to 2.11.11 and 2.12.4

  The use of ValueOf, and consequently the user dependency on Typelevel Scala. Users can now use the Lightbend Scala compiler.
