Spire v0.17.0-M1 Release Notes

Release Date: 2019-06-16 // over 5 years ago

Previous changes from v0.16.0

  • 👍 This version implements major changes; most importantly, Scala 2.10 has been dropped. The commutative ring tower has been precised: Euclidean division has better semantics, and unique factorization domains have been introduced, generalizing spire.math.prime. Some species of division with remainder are now described by TruncatedDivision. An involution typeclass abstracts over complex conjugation. We also revised the use of commutative vs. noncommtutative rings, mostly in the construction of complex numbers/quaternions, and in the definition of modules.

    🚚 Preliminary work has been done towards the modularization of Spire. A platform module abstracts over the JVM/JS differences, while Opt has been moved to the util module. Other modules are not used yet (data, legacy) but will be in the future.

    • Removed support for Scala 2.10
    • Upgraded SBT version to 1.1.5

    • Introduced the platform and util modules
    • Added a few modules for future modularization: legacy, data
    • Introduced unique factorization domains.
    • Renamed quot/mod to equot/emod (Euclidean rings).
    • Introduced principled truncated division semantics (see https://www.microsoft.com/en-us/research/wp-content/uploads/2016/02/divmodnote-letter.pdf ).
    • Added return types to public methods
    • Version upgrades for Scalacheck, Scalatest, Shapeless, Discipline, Machinist and Scala versions
    • Added a docs project using tut, README is compiled under tut.
    • Bug fixes to signum
    • Fixes to Modules (i.e. generalizations of vector spaces) with respect to commutativity, introduced left and right modules
    • Complex numbers and quaternions are now defined on a commutative ring
    • Introduced limited range tests for primitive types,
    • Involution typeclass
