 Also note that some functions are not supported in the new LTA stager. The states that a request can be in have been simplified. As such, there is no need for these functions anymore. Upon use, they will display an error stating that the function is deprecated. Please look at the ''stager_access.py''  file for more information. Also note that some functions are not supported in the new LTA stager. The states that a request can be in have been simplified.
