This release adds:

• A web-based installer using ESP Web Tools if you're using one of the three example configurations. This requires the use of a recent Chrome, Edge or Opera.
• Support for Improv Wi-Fi to set up Wi-Fi on the board using a serial connection from your web browser. Improv Wi-Fi using Bluetooth Low Energy isn't supported because then the Wi-Fi connection crashes.
