+- Update to version 5.0.0 (bsc#1214215)
+ + Remove the --use-token command line option. Aws is deprecating access
+ to instance metadata without authentication token. Ability to access
+ metadat without token has been removed
+ + Support access to the metadata server over IPv6. If the customer
+ enables the IPv6 endpoint for an instance it will be preferred over the
+ IPv4 endpoint
