Maintenance release 2.2.1

• Support Linux

Stable release 2.2.0

• Migrated library to Xcode 9.3
• Ported code to Swift 4.1

Stable release 2.1.0

• Comprehensive support for bit operations on BigInt numbers
• Several bug fixes for existing bit operations

Maintenance release 2.0.5

• Fixes serious bug in division and remainder logic for BigInt numbers
• Support for bit counting (incl. counting leading and trailing zero bits)

Maintenance release 2.0.4

• Adapt to Swift 4.0.2
• Optimize performance of BigInt

Bugfix release 2.0.3

Adopt SPM API Version 4.

Maintenance release 2.0.2

Bug fix to support the Swift Package Manager for Swift 4.

Maintenance release 2.0.1

• Fixes numerous bugs in bit shifting logic
• Makes BigInt a fully integrated SignedInteger in Swift 4
• Re-introduces operations with overflow for Rational (which got lost in the Swift 4 migration)

First release for Swift 4

• Ported NumberKit to Swift 4. Since Swift 4 has backward incompatible numeric APIs, this is a major change that might break existing client usage.
• Added support for toPower(of:) for all integer types.
• Added new operators to BigInt: <<, >>, <<=, >>=, %, %=.
• Introduced new integer protocol: IntegerNumber.
• Renamed protocol FloatNumber into FloatingPointNumber.

Maintenance release 1.6.2

– Fix Rational.toPower(of:) to support negative exponents
– Rename BigInt.dividedBy and BigInt.toPowerOf to make the signatures consistent with the other numerical types
