The new type [KeepAliveConfig] permits fine-tuning the keep-alive
options for TCP connections, via a new [TCPConn.SetKeepAliveConfig]

The new [Request.CookiesNamed] method retrieves all cookies that match the given name....

[Cookie] now preserves double quotes surrounding a cookie value.
The new [Cookie.Quoted] field indicates whether the [Cookie.Value]

Note that the go_darwin_$GOARCH_exec wrapper uninstalls any existing app identified by
the bundle id before installing a new app. If the uninstalled app is the last app by
the developer identity, the device might also remove the permission to run apps from
that developer, and the exec wrapper will fail to install the new app. To avoid that,
install another app with the same developer identity but with a different bundle id.

### Iterators

The new [`iter` package](/pkg/iter/) provides the basic definitions for

If the argument to [FileInfoHeader] implements the new [FileInfoNames]
interface, then the interface methods will be used to set the Uname/Gname
of the file header. This allows applications to override the system-dependent
