changed

• "Pfx.multicast/1" renamed to Pfx.multicast_decode/1 and updated decoding
• Pfx.eui64_encode/1 now also accepts EUI-64 (only needs to flip 7th bit)

• added Pfx.last/1 as a more generic version of Pfx.broadcast/1
• added Pfx.from_hex/1 to create a Pfx.t/0 from any hex string

[v0.4.0] - 2021-07-10

added

• Pfx.eui64_encode/1, which creates a modified EUI-64 from a EUI-48 address
• Pfx.eui64_decode/1, which reverses a modified EUI-64 to an EUI-48 address
• Pfx.flip/2, which flips a single bit in bitstring
• Pfx.insert/3, which inserts some bits into bitstring
• Pfx.remove/3, which removes some bits from bitstring

changed

• Pfx.new/1 and Pfx.from_mac/1 also parse EUI-64 in Cisco's dot format
• Pfx.teredo_decode/1 mirrors the representation for server/client to its pfx argument
• functions raise their own exceptions when marshalling (instead of leaving that up to Pfx.new/1)

[v0.3.0] - 2021-07-08

added

• Pfx.keep/2 to keep some msb bits
• String.Chars for MAC addresses with maxlen 64 (w/ hyphens)

changed

• Pfx.new/1 now parses EUI-48 as well

• Pfx.bor/2, result has same number of bits as its first argument
• Pfx.bxor/2, result has same number of bits as its first argument
• IPv6 addresses in lowercase

fixed

• Pfx.brot/2, won't choke on rotating empty pfx.bits
• Pfx.contrast/2, 1.2.3.0/24 is really to the left of 1.2.4.0/24
