Comment:

 Up for review.

 This will use the same `ChangeLog` format as those used for the other
 RRTypes. Example follows:
 {{{
 564.    [func]          muks
         libdns++: the CNAME, DNAME, MX, NS, PTR and SRV Rdata classes now
         use the generic lexer in constructors from text.  This means that
         the name fields in such RRs in a zone file can now be non-absolute
         (the origin name in that context will be used), e.g., when loaded
         by b10-loadzone. One additional change to the libdns++ API is that
         the existing string constructors for these Rdata classes also use
         the generic lexer, and they now expect an absolute name (with the
         trailing '.') in the name fields.
         (Trac #2390, git a01569277cda3f78b1171bbf79f15ecf502e81e2)
         (Trac #2656, git 5a0d055137287f81e23fbeedd35236fee274596d)
 }}}
