✨ 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

🐛 Bug fix

• 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

🚑 Critical fix

• This version reintroduces the deprecated BigInteger::parse() method, that has been removed by mistake in version 0.8.9 and should have lasted for the whole 0.8 release cycle.

✨ New features

• BigInteger::modInverse() calculates a modular multiplicative inverse
• BigInteger::fromBytes() creates a BigInteger from a byte string
• BigInteger::toBytes() converts a BigInteger to a byte string
• BigInteger::randomBits() creates a pseudo-random BigInteger of a given bit length
• BigInteger::randomRange() creates a pseudo-random BigInteger between two bounds

💩 Deprecations

• BigInteger::powerMod() is now deprecated in favour of modPow()

🐛 Fixes

• added missing ext-json requirement, due to BigNumber implementing JsonSerializable

⚡️ Optimizations

• additional optimization in BigInteger::remainder()

✨ New features

• BigInteger::getLowestSetBit() returns the index of the rightmost one bit
