Changelog

v0.2.0 (2020-01-17)

Abstract classes were replaced with lightweight interfaces for more flexibility. This shouldn't affect most users, but it does break serialization compatibility
IPv4Subnet mask length is now an int instead of an annoying byte, making it consistent with the IPv6 counterpart
Removed deprecated between function
Length type of ranges (Long for IPv4, BigInteger for IPv6) is now a generic parameter of the IPRange/IPSubnet interface. This should make writing generic code that uses IPRange or IPSubnet easier without affecting users of the concrete classes.
New methods in IPv4Address, IPv6Address:
- Logical operators: and, not, or, xor
- toRange, toSubnet
- distanceTo, isAdjacentTo
New methods in IPv4Range, IPv6Range, IPv4Subnet, IPv6Subnet:
- Range extension methods: withFirst, withLast
- intLength
- merge for merging several ranges into a minimal list of non-overlapping ranges

Range and Subnet instances that contain the same addresses are now equal to each other despite being different classes.

The deprecated the between() range builder, replaced it with a new parse() function that accepts subnets (1.2.3.0/24) , ranges (1.2.3.4-1.2.3.5) and single addresses (1.2.3.4).
