A new version of the base IPv6 spec was submitted this morning.  Below is
the list of changes from the previous (July 30, 1997) draft.  If the
new draft doesn't show up soon in the ID directories, I'll make it available
on a public FTP server.

------

    01) In section 3, changed field name "Class" to "Traffic Class" and
        increased its size from 4 to 8 bits.  Decreased size of Flow
        Label field from 24 to 20 bits to compensate for increase in
        Traffic Class field.

    01) In section 4.1, restored the order of the Authentication Header
        and the ESP header, which were mistakenly swapped in the 00
        version of this draft.

    01) In section 4.4, deleted the Strict/Loose Bit Map field and the
        strict routing functionality from the Type 0 Routing header, and
        removed the restriction on number of addresses that may be
        carried in the Type 0 Routing header (was limited to 23
        addresses, because of the size of the strict/loose bit map).

    01) In section 5, changed the minimum IPv6 MTU from 576 to 1280
        octets, and added a recommendation that links with configurable
        MTU (e.g., PPP links) be configured to have an MTU of at least
        1500 octets.

    01) In section 5, deleted the requirement that a node must not send
        fragmented packets that reassemble to more than 1500 octets
        without knowledge of the destination reassembly buffer size, and
        replaced it with a recommendation that upper-layer protocols or
        applications should not do that.

    01) Replaced reference to the IPv4 Path MTU Discovery spec
        (RFC-1191) with reference to the IPv6 Path MTU Discovery spec
        (RFC-1981), and deleted the Notes at the end of section 5
        regarding Path MTU Discovery, since those details are now
        covered by RFC-1981.

    01) In section 6, deleted specification of "opportunistic" flow set-
        up, and removed all references to the 6-second maximum lifetime
        for opportunistically established flow state.

    01) In section 7, deleted the provisional description of the
        internal structure and semantics of the Traffic Class field, and
        specified that such descriptions be provided in separate
        documents.
