⛔ Improvements to error-handling inside Streamlit apps
Version 0.41.0
Release date: June 24, 2019
Highlights:
📈 Greatly improved our support for named datasets in Vega-Lite and Altair
🙄 Added ability to ignore certain folders when watching for file changes. See the server.folderWatchBlacklist config option.
☔ More robust against syntax errors on the user's script and imported modules
Version 0.40.0
Release date: June 10, 2019
Highlights:
Streamlit is more than 10x faster. Just save and watch your analyses update instantly.
We changed how you run Streamlit apps:
  $ streamlit run your_script.py [script args]
Unlike the previous versions of Streamlit, streamlit run [script] [script args] creates a server (now you don't need to worry if the proxy is up). To kill the server, all you need to do is hit Ctrl+c.
