      Release Notes: This is a special-purpose release to coincide with the arrival of "Realm of Racket" in bookstores. It adds a single 'realm' collection, which contains the source code that readers of Realm may wish to use for experiments.

New libraries: JSON, images/flomap, and racket/generic. Racket/string is extended with simplified functions. The class form supports abstract methods. Contracts support interfaces, generics, prompts, continuation-marks, and structs. A new multi-line format for error messages. A new `ffi/com' library replaces MysterX. Completion code for zsh.

                  Release Notes: This release adds improved performance of Redex's matcher, an improved "plot" library, nicer-looking plots, customizable dual axis ticks/transforms, stacked histograms, and 3D vector fields. Performance improvements include using epoll()/kqueue(), cross-module inlining, and using SSE for JIT-compiled floating-point operations. Literal strings, regexps, etc. are interned. DrRacket uses composable ray-traced icons, and Typed Racket allows customizing type errors in macros. "2htdp/universe" supports an experimental game pad key handler. The "db" library now supports nested transactions and PostgreSQL arrays.
