40 # Changelog
41 # ---------
42 # 2006-11-06:
43 # Version 1.0, first release of EasyMAC!
44 #
45 # 2007-07-20:
46 # Version 1.1:
47 # Added option for _any_ MAC address, not only VMware addresses.
48 # Changed output for static/random MAC address. It now tells that these are VMware MAC adresses.
49 #
50 # 2008-10-08:
51 # Version 1.2:
52 # Added option for XenSource MAC address creation.
53 # You can now output MAC address only, without the leading text.
54 #
55 # 2009-04-08:
56 # Version 1.3:
57 # Changed the way XenSource MAC addresses are created.
