* A new `racket/undefined` library exports `undefined` as the
value currently produced by
(letrec ([x x]) x)
This library anticipates a future where that expression will raise
an exception. The `racket/undefined` library will continue to offer
the `undefined` value as a bridge between versions and as a last
resort.
* The drawing and GUI libraries provide improved support for
high-resolution bitmaps and their use on Retina displays. For
example, `read-bitmap` includes a `#:try-@2x?` option to trigger
substitutions through the usual "@2x" naming convention.
