This is not what `add X#julia-0.7` does; it says that the _project_ (or package) depends on `X`, and that the _environment_ (i.e. Manifest) should track the `julia-0.7` branch. Since there’s only one environment active, that does not work as a general strategy (i.e. you could work in X’s environment, but then Y’s dependency on Z#julia-0.7 will be ignored). AFAIK, there’s no way to say that a _package_ depends on some branch of another package. However, you can still have an _environment_ in which all the branches you want are loaded:

In your top-level environment (eg. v0.7), dev path\_to\_package1, dev path\_to\_package2, etc. Then work from your top-level environment. Each package will know how to find its dependencies, and you just told Pkg that in the current (top-level) environment, you want to use the development version of all your packages. What really confused me was that (MyPackage) pkg\> ad…
