x.xx

* 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

v1.41

* Generate v6 RRD DS in contrib/sync_ds.pl too
	(spotted by Peter Hansen)

* sFlow: fix creation of new RRDs when multiple entries with the same
	tag are present in the known links file
	(spotted by Michal Buchtik)

	(contributed by Michal Buchtik)

	knownlinks file.

v1.40

*	Add support for NetFlow v9 to netflow-asstatd.pl
	(sponsored by Xplornet Communications Inc.)

*	Add support for IPv6 (for NetFlow v9 and sFlow). Note: existing
	RRDs need to be upgraded (new data sources added for v6) for
	this to work. Enable $showv6 in www/config.inc to see separate
	graphs for IPv6.

*	Add support for 4-byte ASNs (NetFlow v9 and sFlow). Needs testing.

*	Add RRA for 1 month at 4 hour resolution to newly created RRD files.

*	Add links to PeeringDB and robtex
	(suggested by Steve Glendinning)

*	Fix AS-SET lookup on systems where the whois command returns
	additional lines.

v1.36

*	Fix creation of new RRDs when multiple entries with the same
	tag are present in the known links file
	(spotted by Michel Moriniaux)

*	Add feature to inspect all ASes in an AS-SET (automatic whois	lookup).
	(contributed by Nicolas Debrigode)

*	Updated asinfo.txt with data from whois.cymru.com.

v1.35

*	Allow hyphens in link names.	(contributed by Gareth Campling)

*	Smooth I/O burstiness and reduce overall IOPS requirements
	by flushing only 10% of the cache every 25 seconds (instead
	of the entire cache at once every 60 seconds).
	(contributed by James A. T. Rice)

v1.34

*	Fix for NaN detection in rrd-extractstats.pl for
	64-bit Perl versions
	(contributed by Benjamin Schlageter)

*	Skip missing data sources in rrd-extractstats.pl to avoid
	abort if new data sources are added but the RRDs are not
	updated.

v1.33

*	Fix for multiple entries with the same tag in the
	knownlinks file (e.g. for LACP)
	(contributed by Michal Buchtik)

*	Added sync_ds.pl script to contrib directory, which can
	synchronize the data sources of RRD files with the tags
	defined in the knownlinks file
	(contributed by Michal Buchtik)

*	sflow-asstatd.pl now uses the agent IP instead of the
	UDP source address - this makes it behave properly when
	a proxy is being used
	(contributed by Michel Moriniaux)

v1.32

*	Fix add_ds.sh to support new directory structure
	(contributed by Sergei Veltistov)

*	Fix PHP warnings and move $ntop to config.inc
	(contributed by Michal Buchtik)

*	Set memory_limit to 256 MB in PHP pages (suggested by Steve Colam
	<steve@colam.co.uk>).

*	Allow NetFlow aggregation version 0 as well as 2 to make NetFlow 
exports from Juniper routers work (suggested by Thomas Mangin
 	<thomas.mangin@exa-networks.co.uk>).

*	Updated asinfo.txt with data from whois.cymru.com.
