Prakash, Are you referring to this mailing list thread [1]? If so that’s more or less an implementation detail in how TripleO deploys a cloud, and has absolutely no bearing on the API’s offered by Heat itself. If you’re looking for information on API’s, resources, or other functionality being deprecated over time, I’d suggest having a look at the Heat release notes. [2] The Heat API has been rather stable for some time now, though there have been a few resources deprecated over the past several releases (often following the underlying project that the resource supports—Nova or Neutron for example—deprecating something). At Your Service, Mark T.

Based on the triplo deprecating tripleo-heat-template, appears there are deprications and we did have been requesting help to review the add-ons to interop What do you mean 'triplo deprecating tripleo-heat-template'?
