 * The `case' form dispatches on characters, fixnums, symbols, and
   keywords in logarithmic time (thanks to Jon Zeppieri).

 * The new `racket/format' library provides new and improved
   string-formatting functions.

 * Logging tools include improved filtering support based on the name
   of a logger. A new `define-logger' form simplifies the use of named
   loggers. Forms such as `log-debug' now support string formatting.

 * The `for' form now supports `#:break' and `#:final' clauses.

 * The new PLTCOMPILEDROOTS environment variable configures the search
   path for compiled bytecode.

These seem too minor for a release announcement.
