 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).
