For each new update, please run the Slot generator again and repopulate all of your slots with the output. If you don't do this, the skill might seem to successfully build and save, but those with large libraries may encounter issues at runtime. There might be new slots needed for new functionality as well.
Remember to always update the Intents and Utterances in the skill. If new slots were added, you will need to add those as well.
Please also check the current kodi.config.example template for new configuration variables that you may need to set.
Almost anything else can change, too. Please be sure to check the CHANGELOG and README again when updating.
Just delete the existing app from your Heroku Dashboard, and create another with the button below with the same name you gave earlier.
If you are not using Zappa yet, please go back to the README file there and start from scratch.
If you are already using Zappa, browse to the application directory in your terminal. Then activate the virtualenv with:
virtualenv venv and source venv/bin/activate (if you are on Windows, that's venv\Scripts\activate.bat or venv\Scripts\activate.ps1 for Powershell).
Finally, execute all of the following:
git pull origin master
pip install zappa --upgrade
pip install -r requirements.txt
zappa update dev
