No changes in the public API, but the anonymization of IPv4-compatible and IPv4-mapped IPv6 addresses has changed to use the IPv4 mask on the IPv4 part.
If an address is of the form x:x:x:x:x:x:d.d.d.d and begins with 96 zeros or 80 zeros + 16 ones, then the actual mask used is 96 + the IPv4 mask. Previously, the IPv6 mask was used for all cases in this form.
The new behavior for this case is:
anonymize('::ffff:123.123.123.123') // -> '::ffff:123.123.123.0'
anonymize('::123.123.123.0') // -> '::123.123.123.0'- Resolves issue #2
