 This is where each new PR to the project should add a summary of its changes,
 which makes it much easier to fill in each release's changelog :)
 
-- Replace `template_path` with `template_paths` [#1532](https://github.com/ipython-contrib/jupyter_contrib_nbextensions/pull/1532). Nbconvert 6.0 replaced `template_path` with `template_paths` (see https://nbconvert.readthedocs.io/en/latest/changelog.html#significant-changes). This change in Nbconvert 6.0 causes errors in jupyter_latex_envs and in jupyter_contrib_nbextensions (see [#1529](https://github.com/ipython-contrib/jupyter_contrib_nbextensions/issues/1529).

 The template needs to be in a path where nbconvert can find it. This can be your local path or specified in 
-`jupyter_nbconvert_config` or `jupyter_notebook_config` as `c.Exporter.template_paths`, see [Jupyter docs](https://jupyter-notebook.readthedocs.io/en/latest/config.html).
+`jupyter_nbconvert_config` or `jupyter_notebook_config` as `c.Exporter.extra_template_basdirs`, see [Jupyter docs](https://jupyter-notebook.readthedocs.io/en/latest/config.html).
 
 For HTML export a template is provided as `nbextensions.tpl` in the `jupyter_contrib_nbextensions` templates directory. Alternatively you can create your own template:
 ```
