modified to not create whole datagram fragments (Fragment Offset field and the M flag are zero). See [RFC6946] and [RFC8021] for more information.

o Removed the paragraph in Section 5 that required including a Fragment header to outgoing packets if an ICMP Packet Too Big message reporting a Next-Hop MTU is less than 1280. See [RFC6946] for more information.

o Changed the text to require that IPv6 nodes must not create overlapping fragments. Also, when reassembling an IPv6 datagram, if one or more of its constituent fragments is determined to be an overlapping fragment, the entire datagram (and any constituent fragments) must be silently discarded. Includes clarification that no ICMP error message should be sent if overlapping fragments are received. See [RFC5722] for more information.

o Revised the text to require that all headers through the first upper-layer header are in the first fragment. See [RFC7112] for more information.

o Incorporated the updates from [RFC5095] and [RFC5871] to remove the description of the Routing Header type 0 (RH0), that the allocations guidelines for Routing headers are specified in RFC 5871, and removed RH0 from the list of required extension headers.

Security issues relating to other parts of IPv6 including addressing, ICMPv6, Path MTU Discovery, etc., are discussed in the appropriate specifications.
