Hi, I have an application that is about to be moved into production. Currently it is pulling "stable" or sometimes bleedingEdge of other configurations. After the system moves from testing into production I would like to have tight control of which packages are updated from one version to another. E.g. not have a Voyage "stable" upgrade just because there is a new stable version but probably at the same time still use a symbolic reference myapp-stable-5 to load the package? Is there a common/known to work approach. I could identify all used Metacello configs and move them to my own infrastructure and then copy the use packages as well. Is there tooling support for adding such a "freeze"? How do other handle a release of an application that needs to be updated in an "incremental" way? cheers holger
