* 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. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
