According to Google’s official support page listing the current firmware versions of its speakers and smart displays, version 14.20230831.4.72 is now available to those enrolled in the Preview Program (which can be accessed via the Google Home app). These updates are often released in stages, meaning it may be a few weeks before your Nest Hub gets the latest build.
On the project’s website, Google offers a more in-depth look at what has changed in Fuchsia version 14 (as well as version 13, which the Nest Hubs skipped). Most of the changes will only be relevant to Fuchsia developers, but there are a handful of user-facing improvements.
Google is providing some very detailed release notes for each version of Fuchsia, which are quite interesting to peruse. The recent layoffs at Google hit the Fuchsia team hard, likely reducing its future prospects as Google’s unified consumer-facing operating system, but that clearly doesn’t mean it’s entirely dead in the water.
