⚡️ Performance improvements

• BigNumber::of() is now faster, thanks to @SebastienDug in #77.

💥 Breaking changes

• Minimum PHP version is now 8.1
• RoundingMode is now an enum; if you're type-hinting rounding modes, you need to type-hint against RoundingMode instead of int now
• BigNumber classes do not implement the Serializable interface anymore (they use the new custom object serialization mechanism)
• The following breaking changes only affect you if you're creating your own BigNumber subclasses:
  • the return type of BigNumber::of() is now static
  • BigNumber has a new abstract method from()
  • all public and protected functions of BigNumber are now final

💥 Breaking changes

• Minimum PHP version is now 8.0
• Methods accepting a union of types are now strongly typed^*
• MathException now extends Exception instead of RuntimeException

^{* You may now run into type errors if you were passing Stringable objects to of() or any of the methods internally calling of(), with strict_types enabled. You can fix this by casting Stringable objects to string first.}

👌 Improvements

• BigRational::toFloat() now simplifies the fraction before performing division (#73) thanks to @olsavmic

✨ New features

• BigInteger::gcdMultiple() returns the GCD of multiple BigInteger numbers

💥 Breaking changes

• Minimum PHP version is now 7.4

🚀 Compatibility with PHP 8.1

• Support for custom object serialization; this removes a warning on PHP 8.1 due to the Serializable interface being deprecated (#60) thanks @TRowbotham

🐛 Bug fix

• Incorrect results could be returned when using the BCMath calculator, with a default scale set with bcscale(), on PHP >= 7.2 (#55).

✨ New features

• BigInteger::not() returns the bitwise NOT value

🐛 Bug fixes

• BigInteger::toBytes() could return an incorrect binary representation for some numbers
• The bitwise operations and(), or(), xor() on BigInteger could return an incorrect result when the GMP extension is not available

👌 Improvements

• BigNumber::of() now accepts .123 and 123. formats, both of which return a BigDecimal

💥 Breaking changes

• Deprecated method BigInteger::powerMod() has been removed - use modPow() instead
• Deprecated method BigInteger::parse() has been removed - use fromBase() instead
