Plus the 32-bit Windows repair:

 * Mac OS X Yosemite: fixed compatibility problems, mainly by patching
   the Pango text-drawing library that is bundled with Racket.

 * Windows, 32-bit version: fixed window-update crashes by patching the
   Cairo drawing library that is bundled with Racket.

 * Windows: made the GUI library DPI-aware.

 * Added a "binary library" installation mode to install packages
   without source or documentation. Use the `--binary-lib` option with
   `raco pkg install`.

 * Repaired the compiler's use-before-defined analysis for certain
   forms of nested `letrec`, some `let` forms, and some uses of `set!`
   or `with-continuation-mark`.

 * Added bytecode optimizations (thanks to Gustavo Massaccesi).

 * Added a `replace-evt` event constructor (as suggested by Jan Dvořák).

These seem too minor for the announcement.
