<<StackHeader(unique_identifier)>>

== Overview ==

This stack defines a ROS message for a [[http://en.wikipedia.org/wiki/Uuid|universally unique identifier (UUID)]], as described in [[http://tools.ietf.org/html/rfc4122.html|RFC 4122]].

It also provides Python and C++ interfaces for managing UUIDs.

== Release History ==

This stack was originally released for Fuerte (without the [[unique_id]] C++ API). 

For Groovy, the C++ [[unique_id]] API was added.

For Hydro, the packages were converted to build using [[catkin]]. The `unique_identifier` stack became an empty meta-stack, depending on `uuid_msgs` and `unique_id` for backwards compatibility with rosbuild stacks. Catkin packages should depend on those packages directly, not depending on `unique_identifier`.

The interface is now ''stable''.
