Google releases major updates to Lighthouse approximately once a year, with smaller, incremental updates happening more frequently. To stay informed about future updates, it's a good idea to follow the official Lighthouse GitHub repository (https://github.com/GoogleChrome/lighthouse) and the Lighthouse section of the Google Developers website (https://developer.chrome.com/docs/lighthouse/). You can also subscribe to relevant newsletters and forums to stay updated on the latest news and discussions around Lighthouse and web performance optimization.
