- Add more guards against trying to analyze captured packets with a truncated IPv6 static header or extension header chain. - Add back in the ICMP payload tracking for ICMP "connections". - Fix 'icmp_context' record construction. Some field assignments were mismatched for ICMP and ICMP6. Source and destination addresses were set incorrectly for context packets that don't contain a full IP header. Some fields for ICMP6 weren't filled out. - Changed ICMP Time Exceeded packets to raise the 'icmp_time_exceeded' event instead of 'icmp_error_message'. - Add unit tests for truncation and the main types of ICMP/ICMP6 that have specific events. - Documentation clarifications.
