 * Fixed `$path` values that point outside the project folder failing to match `syncRule`s on Windows, which broke `rojo sourcemap` with a "could not be turned into a Roblox Instance" error. ([#1290])
 * Fixed `rojo serve` silently stopping syncing file changes on Windows when the served project path was a verbatim (`\\?\`) path, because tree paths and file-watcher event paths were canonicalized to different forms. ([#1290])
 * Fixed `rojo sourcemap --absolute` emitting verbatim (`\\?\`) paths on Windows, which broke require types in luau-lsp. ([#1290])
+* The plugin now disables the `Check for Updates` setting if you block access to `api.github.com`. ([#1297])
