1.0.0-alpha.5

Additions to Interval:

• minus and plus operations.
• lowerBound, upperBound, isLowerBoundIncluded, and isUpperBoundIncluded accessors, preventing you from having to repeatedly check isReversed.
• Interval now implements IntervalUnion, as a union with a single interval.

Additions to IntervalUnion:

• isEmpty
• getBounds to get upper and lower bounds of the set.

Dependency updates:

• Kotlin 1.9.23
• kotlinx-datetime 0.5.0

1.0.0-alpha.4

• Added an initial contract definition for IntervalUnion (a collection of intervals) and preliminary concrete MutableIntervalUnion which lives up to the contract by restricting which intervals can be added.
• Added Interval.reverse and nonReversed.
• Added Interval.intersects to check whether one interval intersects with another.

1.0.0-alpha.3

Introduced date/time intervals as InstantInterval using the kotlinx datetime library, published as a separate artifact under the same namespace: kotlinx-interval-datetime.

1.0.0-alpha.2

• Added Interval.contains (in) operator to check whether values lie in an interval.
• Added interval constructor functions so that all interval types can be constructed using the same keyword.

1.0.0-alpha.1

A first functional, but still unstable, release.

The base type representing open/closed intervals with generic T and TSize has been introduced. The only operations at the moment is a size property. Default intervals are included for all basic Kotlin types, e.g. IntInterval, DoubleInterval, etc.
