Sorry if this is not relevant to your use of LightGraphs, but I wanted to make sure everyone's aware of a change in the API for the `induced_subgraph()` function.
Starting in LightGraphs 0.7.1, `induced_subgraph()` will, in addition to the subgraph itself, return a mapping of the original vertex indices to the new ones. This will require code changes to ignore the new return value if you’re using this function. If you’re using the `getindex` version of `induced_subgraph` (that is, `g[1:5]`), there will be no change. Please feel free to file issues over at LightGraphs.jl if you run into problems.
