```
server.Server.versionAtLeast(minimum: : string) -> Promise<boolean>
```

Whether this server is at least `minimum`, written the way tmux writes it.

This is how a caller gates on a feature that arrived in a known release
without parsing `#{version}` themselves. Development builds such as
`next-3.8` compare above every tagged release.

## Example

```ts
if (await server.versionAtLeast("3.3")) {
  await server.setOption("extended-keys", "on");
}
```
