The change of note here is that the compiler's output of file paths is now relative to the project (src/myfile.erl) rather than in _build/<profile>/lib/libname/src/myfile.erl.

To retrieve the old behaviour, add {compiler_source_format, build} in your rebar config (you may prefer to do it in the global file). We have also added {compiler_source_format, absolute} for absolute paths (based on the project, not _build).
