- * Added support for the HIP RR type.
+ * Added a to_digestable() method to rdata classes; it returns the
+ digestable form (i.e. DNSSEC canonical form) of the rdata. For
+ most rdata types this is the same uncompressed wire form. For
+ certain older DNS RR types, however, domain names in the rdata
+ are downcased.

- * dns/query.py (udp): When checking that addresses are the same,
- use the binary form of the address in the comparison. This

- equivalent but differing textual representations. E.g. "1:00::1"
- and "1::1" represent the same address but are not textually equal.
