Libra v0.3.0 Release Notes

Release Date: 2017-12-26 // over 6 years ago
  • ๐Ÿš€ 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:

    ๐Ÿ†• New units

    ๐Ÿ“ฆ 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.

    ๐Ÿ†• 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.

    ๐Ÿ†• New operations

    ๐Ÿ‘ Quantities now support Euclidean division with spire's /~ quotient operator

    โฌ†๏ธ Upgrades

    โฌ†๏ธ 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.
