+Racket v6.1.1
+
+* The MAC OS X YOSEMITE compatibility problems are fixed. We
+  bundled a patched Pango text-drawing library with Racket.
+
+* The WINDOWS [32-bit] releases fixes the window-update crashes.
+  We bundled a patched Cairo drawing library with Racket.
+
+* TYPED RACKET closes two safety holes in the exception system.
+  The revised type system restricts `raise' to send only
+  instances of the `exn' structure type and flat data to
+  handlers. It also checks exception handlers properly.
+  NOTE: Previously well-typed programs may fail to typecheck.
+
+* TYPED RACKET'S typed regions support casts and predicates.
+
+* 2HTDP/IMAGE'S notion of equality ignores an image's baseline.
+
+* The PACKAGE MANAGER supports a binary library installation mode,
+  which allows users to install packages without source or documentation. 
+  Use the `--binary-lib' option with `raco pkg install'.
+
+* The new DRRACKET-TOOL-LIB package factors out parts of DrRacket's
+  IDE so that they can be reused with other editors, such as Emacs.
+
+* The COMPILER'S use-before-defined analysis has been repaired for
+  certain forms of nested `letrec', some `let' forms, and some
+  uses of `set!' or `with-continuation-mark'.
+
+* The COMPILER performs additional bytecode optimizations.
+  Thanks to Gustavo Massaccesi.
+
+* The CML library comes with a new `replace-evt' event constructor.
+  Thanks to Jan Dvořák.
+
+* REDEX'S benchmark suite comes with a description of the benchmark
+  programs.
+
+* REDEX'S metafunctions can be typeset using the "large left brace"
+  notation for conditionals.
+
+* The CONTRACT library comes with an improved `contract-stronger?'.
+  Its error messages note that the contract itself might be wrong.
+
+* The GUI library is DPI-aware on Windows.
+
+* The OPENSSL library supports Server Name Indication for servers.
+  Thanks to Jay Kominek.
+
+* The SYNTAX/PARSE library allows the definition of new pattern
+  forms via pattern expanders, similar to match expanders.
+  Thanks to Alex Knauth.
+
+* OpenGL on Linux no longer depends on libgtkgl, and core profiles
+  are supported (see `set-legacy?').
+
+* The TEACHING LANGUAGES' unit test framework supports
+  `check-satisfied', a construct for checking whether a result
+  satisfies a predicate, e.g.: (check-satisfied (sort l) sorted?)
