About Lifesize
Lifesize feed has degraded to scraped UI chrome.
There is no real product signal in the recent Lifesize feed. The 'entries' are scraped page fragments — site-nav language switchers, popup-dismiss text, a chat-widget greeting, the converse360 chatbot loader, and product-page boilerplate noting the Enghouse Systems acquisition. No release notes, no shipped features, no version events.
