 Each new *stable* release should follow the following steps, the first of which can occur in two ways:

   - **Pre-merge** at least one commit in :code:`dev` for the PR against master, such that the merge will include updating the version string. In the illustration below, this is depicted by the dashed borders around the final merge into :code:`master`.
 
   - **Post-merge** making a final commit to :code:`master` updating the version string. In the illustration below, this is depicted by the "final push" dashed commit circle on :code:`master` right before "tagged manual release" of :code:`v0.7.2`.
 
 - Step 2: manually trigger a release on Github using a :code:`vM.N.P` version string where :code:`M.N.P` matches Step 1. In the illustration below, this is depicted by the right-most, salmon-colored "tagged manual release" commit to :code:`master`.

 - Step 3: immediately bump the version string on :code:`dev` to :code:`M.N.P+1.dev0` where :code:`M.N.P` refers to the version string from Step 1. In the illustration below, an example is shown on the left-side of the diagram immediately to the right of the "tagged manual release" of :code:`v0.7.1` on :code:`master`.

 ==========
 Historically :code:`pymer4` versioning was a bit all over the place but has settled down since 0.5.0. This page includes the most notable updates between versions but github is the best place to checkout more details and `releases <https://github.com/ejolly/pymer4/releases/>`_.

+- **Compatibility updates:**
+    - This version drops official support for Python 3.6 and adds support for Python 3.9. While 3.6 should still work for the most part, development support and testing against this version of Python will no longer continue moving forward.
+- **New features:**  
+    - :code:`utils.result_to_table` function nicely formats the :code:`model.coefs` output for a fitted model. The docstring also contains instructions on using this in conjunction with the `gspread-pandas <https://github.com/aiguofer/gspread-pandas>`_ library for "exporting" model results to a google sheet
