There&#8217;s a higher chance of buggy, broken, and potentially harmful elements being distributed.&#13;<\/p>\n<p>The initial builds are also intended to help developers learn about the operating system changes before the final public release later in 2026. It&#8217;s not meant to be used by consumers.&#13;<\/p>\n<p>Unless you have a vested interest in using them, such as app development, don&#8217;t install the early developer betas.&#13;<\/p>\n<p>Instead, members of the public should seek out the public betas, when they become available.&#13;<\/p>\n<p>Find any changes in the new builds?
