 Note: add `--sys-prefix` to `jupyter nbextension` to install into virtualenv or conda environment.
 
-## Upgrading from 0.3.1?
-Versions prior to 0.4 were installed by bootstrapping custom.js and jupyter configuration files. Pip uninstall does not remove these files. Upgrade to 0.4, then run `python -c "import hide_code; hide_code.uninstall_bootrapped_files()"`.
+## New in 0.5.0
+* Export Reveal.js slides or latex templates.
+* Support for nbconvert 5.x+ and notebook 5.x+.
 
 ## Documentation
 Visit the [Wiki](https://github.com/kirbs-/hide_code/wiki).
 
 ## Requirements
