I just installed a new version 1.6.6 of WireShark to analyze Zigbee network
packets, however my traffic is encrypted and the newer version does not seem to
be decrypting the data correctly.  It shows the same behaviour as the Linux
release of 1.6.5 as well.  I have not been able to get packets to decode on
Win64 1.6.6 or Linus 1.6.5 versions.  However, Win32 and Win64 releases of
1.6.5 DO decode the encrypted data correctly.

If you load the file that I attached, it includes encrypted data as an example.
 Since the key is transmitted in palin text over the network, WireShark
(Win32/64 1.6.5 version) has been able to find the (Transport) key
automatically and decrypt all the following data transmissions, but the
behaviour is different in version 1.6.6 in which the automatic decrypting has
not been working.

I am attaching a file for an example of data that automatically decrypts in
version 1.6.5 (win32/64) but not in the current release (win32/64) 1.6.6 or
(Linux) 1.6.5.
