Changes: * 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 Dvorak. * 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?) |
