https://issues.jboss.org/browse/JBIDE-17965 The stacks urls for stacks.yaml etc have changed. The old URLs still work for now, but I suppose this isn't guaranteed forever. We currently use stacks-client 1.0.0. We currently pull the stacks.yaml url from inside our client. Our client includes the old URL. If we want to continue pulling from the client, then we need a new client. If we update to a new client, we need to deal with changed package names. This will most likely affect stacks, server, and central (I think?) So... 2 options here: 1) I stop pulling stacks.yaml url from the client jar and just hard-code our default url 2) I update to stacks client 1.1.0.CR1, and we deal with changed package names throughout the product. Advice needed.
