v1.6

• Added support for multiple links on one ifIndex, based on VLANs. Only sFlow, Netflow v9 and v10 (IPFIX) support this. Obviously your router needs to provide the information. Just add "/" to the ifIndex in your knownlinks file.
• Added support for peer-AS stats/graphs (sFlow only).
  • Add -n option to asstats.pl and set showpeeras=true in config.inc to enable.
    Top N AS intervals are now configurable (see config.inc and README), and separate top stats files can be used per interval (enables e.g. proper weekly/monthly stats).
• Added Terabyte formatting.

v1.5

• Merged netflow-asstatd.pl and sflow-asstatd.pl into one script so
  that it can handle NetFlow and sFlow sources concurrently
  (contributed by Wouter de Jong). Please note the following changes:
  • The sampling rate command line parameter (-s) has been removed. Instead, the sampling rate must now be specified for each link in the knownlinks file to avoid confusion with prior defaults. If you're using NetFlow without sampling, you need to add the sampling rate 1 to each link.
  • The command line parameter to set the sFlow listen port has been changed to -P to avoid a clash with the NetFlow port parameter (-p).

v1.43

• Add v6 data sources to add_ds_proc.pl
• Remove closing tag from config.inc to prevent whitespace problems in gengraph.php
• Fix security issue in gengraph.php/linkgraph.php
• Updated asinfo.txt with data from whois.cymru.com.

v1.42

• Try harder to determine IP version for sFlow samples.
• Add IPFIX support (contributed by Daniel Piekacz)
• Add experimental NetFlow v5 support (contributed by Charlie Allom)
• Fix handling of 64-bit counters for NetFlow v9
