eg

  "mpas_analysis.configuration":{
    "__set__":true,
    "elements":[
      "mpas-analysis-1.2-py_0",
      "mpas-analysis-1.2.1-py_0",
      "mpas-analysis-1.2.2-py_0",
      "mpas-analysis-1.2.3-py_0",
      "mpas-analysis-1.2.3-py_1",
      "mpas-analysis-1.2.4-py_0",
      "mpas-analysis-1.2.4-py_1",
      "mpas-analysis-1.2.4-py_2",
      "mpas-analysis-1.2.5-py_0",
      "mpas-analysis-1.2.5-py_1",
      "mpas-analysis-1.2.6-py_0",
      "mpas-analysis-1.2.6-py_1",
      "mpas-analysis-1.2.6-py_2",
      "mpas-analysis-1.2.6-py_3",
      "mpas-analysis-1.2.7-pyh9f0ad1d_0",
      "mpas-analysis-1.2.7-pyh9f0ad1d_1",
      "mpas-analysis-1.2.7-pyh9f0ad1d_2",
      "mpas-analysis-1.2.7-pyh9f0ad1d_3",
      "mpas-analysis-1.2.8-pyh9f0ad1d_0"
    ]
  },

would state that mpas_analysis.configuration is provided by mpas-analysis for versions 1.2 - 1.28
