+Check for a new version of OpenCode and install it. If a newer OpenCode 1 release is available, the dialog installs it. If OpenCode 1 is up to date, it offers to upgrade you to OpenCode 2.0 instead. OpenCode never installs updates on its own, so a notice on the home screen tells you when one is available. Choosing **Skip** on an OpenCode 1 update hides the notice until a newer version is released, and choosing **Dismiss** on the OpenCode 2.0 offer hides it for a week.
