Version 5.6.2

Avoids exceptions occurring in environments or with deployments where Package objects are null, issue seancfoley/IPAddress#147.

Version 5.6.1

Adjusts prefix lengths in containment tries for all individual addresses.

Version 5.6.0

This version introduces new types for efficient IP address collections and set operations, along with a few other enhancements

• added IPAddressSeqRangeList, a collection type backed by IP address ranges, offering binary search, an alternative to tries with potentially better CPU cache coherence when searching
• IPAddressSeqRangeList enables the arithmetic set operations add/join, intersect, remove, and complement
• added the corresponding version-specific types IPv4AddressSeqRangeList and IPv6AddressSeqRangeList
• added IPAddressContainmentTrie, an alternative collection option backed by CIDR prefix blocks in a trie, expanding on the existing trie functionality.
• added the corresponding version-specific types IPv4AddressContainmentTrie and IPv6AddressContainmentTrie
• added the IPAddressCollection interface representing collections of individual addresses, implemented by all range list and containment trie types
• added the IPAddressAggregation interface representing all types which can represent a multitude of IP addresses, whether collections, ranges, or subnets
• added new and optimized increment(), decrement() and incrementBoundary() methods to the address types, more efficient than increment(1), increment(-1), incrementBoundary(1)
• extended increment(BigInteger) to the address/subnet types IPAddress and IPv4Address, and not just IPV6Address, for easier polymorphism
• added a complement method to IPAddress returning blocks, and a complement method to IPAddressSeqRange returning ranges, in addition to the complement method included with IPAddressSeqRangeList
• added methods to IPAddressSeqRange to integrate with IPAddressSeqRangeList to create lists efficiently: subtractIntoList, joinIntoList, complementIntoList
• added intoSequentialRangeList methods to IP address and sequential range classes for polymorphic and efficient IPAddressSeqRangeList creation
• added intoContainmentTrie methods to IP address and range classes for polymorphic IPAddressContainmentTrie creation
• added new trie types IPAddressTrie and IPAddressAssociativeTrie, similar to existing types, but version-polymorphic, they can become either IPv4 or IPv6 tries, but not both at the same time
• fixed an issue with merging addresses with prefixes into sequential blocks

Version 5.5.1

• added new merge functions mergeToDualPrefixBlocks and mergeToDualSequentialBlocks for combined IPv4/IPv6 merging
• added public constructors accepting message strings to AddressValueException and IncompatibleAddressException, issue #127
• removed caching functionality from containingFirstIterator, use all-node containingFirstAllNodeIterator instead

Version 5.5.0

• added collection types for dual IPv4/v6 tries and for dual IPv4/v6 associative tries, issue #103
• trie performance improvements for all trie operations
• added shortestPrefixMatch trie methods
• added enumerate methods, the inverse of the increment methods, to find the position of an address in a subnet, or to find the distance between two addresses
• added an increment method accepting a BigInteger argument to IPv6Address and IPv6AddressSection
• added the ability to construct an IPv6Address from two longs
• added replace methods with address section parameter to address classes
• added overlaps methods to check for overlapping subnets, and for checking sequential range overlap with a subnet
• added floor/lower/ceiling/higher methods to the address trie types, these methods previously accessible only from trie sets
• added the extraneous digits IPv4 parsing option allow_inet_aton_extraneous_digits, issue #105.
• includes the fix to invalid radix argument infinite loop, issue #118

Version 5.4.2

• removed unnecessary SDK dependency incompatible with Java 8 that was introduced with version 5.4.1, issue #121
• includes the fix to invalid radix argument infinite loop, issue #118

Version 5.4.1

• fix to invalid radix argument infinite loop, issue #118
