According to my monitoring of https://support.google.com/product-documentation/answer/10231940?hl=en, the following models have reached end of life today or yesterday, as they won't receive any further critical security updates: Chromecast (2nd gen) Chromecast Audio Chromecast Ultra Chromecast (3rd gen) Chromecast with Google TV (4K) and Chromecast Voice Remote I haven't seen any press release so far, so I thought I'd let you know. EDIT: Google has reverted the change, meaning the models above are still supported. submitted by /u/the-ridah [link] [comments]
