Migration from version 4.x to 5.x
In this version the inline JavaScript has been moved to a separate file to better comply with a Content Security Policy (CSP). If you dynamically load or display the captcha element, you probably need to initialize the captcha manually:
Make sure the JavaScript file is included in your page: EXT:bw_captcha/Resources/Public/JavaScript/Frontend/Captcha.js
Migration from version 3.x to 4.x
This version aims to make solving the captcha more accessible. It introduces a new audio feature that reads out the
current captcha code. Missing ARIA properties have been added.
- Check out the new captcha partial
- Audio button is enabled by default (can be disabled via
plugin.tx_bwcaptcha.settings.audioButton)

tl;dr:
- Check out the new captcha partial
- Reload button is enabled by default (can be disabled via
plugin.tx_bwcaptcha.settings.refreshButton) - You can re-enable the page cache, if disabled it because of this element
