Changelog

This project adheres to Semantic Versioning.

[7.0.0] - TBD

Changed

  • The Rx and Ix extension methods have been removed.

Fixed

  • Changed netcoreapp2.0 support to netcoreapp3.0 to avoid high-security vulnerabilities.

[6.2.2] - 2021-09-25

Changed

  • Bump Rx and Ix dependencies.

[6.2.1] - 2021-09-25

Fixed

  • Explicity support net461 so that shim dlls are not required on that platform.

[6.2.0] - 2021-03-07

Added

  • ignoreOrder option for EquateSequence to ignore order of elements when comparing for sequence equality.

[6.1.0] - 2020-10-24

Added

  • IFullComparer<string>.ToStringComparer to easily create a StringComparer instance.
  • FixedStringComparer to provide StringComparer instances that do not throw on null.
  • Nullable reference type checking.
  • Added AdvancedComparerBase<T> and AdvancedEqualityComparerBase<T> for advanced scenarios.

Fixed

  • Static constructors for derived types are always invoked (so they set DefaultComparer), even if an instance is not ever created. #34

Changed

  • Hash algorithm is now Murmur3.

[6.0.0] - 2019-03-16

See v6 upgrade guide.

Changed

  • Some type names used in the builder pattern. Most users will not be affected.
  • Plain IComparer<T> types must now declare a GetHashCode implementation to be used with Nito.Comparers.
  • ReferenceEqualityComparer is now restricted to reference types.

Added

  • "Fix comparer" extension methods to apply default null handling to misbehaving comparers.

Removed

  • BinarySearch overloads that allowed defining the comparer inline.

[5.0.7] - 2019-02-12

Added

  • Source link support.

[5.0.6] - 2019-02-12

Fixed

  • Corner cases for comparers and equality comparers.
  • IEqualityComparer.GetHashCode when called with an unexpected type.
  • Stack overflow when IComparer.Compare is called for objects of different types that each forward their IComparable implementation to that method.
  • Stack overflow in EqualityComparerBase.IEqualityComparer.Equals corner case.
  • Fixed #12: when comparison methods are passed invalid types (using the nongeneric IEqualityComparer or IComparer interfaces), they could throw InvalidCastException or NullReferenceException.

[5.0.5] - 2017-09-09

Fixed

  • Revert public signing.

[5.0.4] - 2017-08-26

Added

Changed

  • Build scripts.

[5.0.0] - 2017-02-27

See v5 upgrade guide.

Changed

  • NuGet package is now Nito.Comparers instead of Comparers.
  • Better names for types used in the "builder" pattern for comparers.
  • allowNulls parameter name changed to specialNullHandling.
  • Equality comparer types moved from Nito.EqualityComparers namespace to Nito.Comparers.

Removed

  • The anonymous comparers have been removed.
