* Performance improvements include the use of epoll()/kqueue() instead of select() for the Racket thread scheduler, cross-module inlining of small functions, and the use of SSE instead of x87 for JIT-compiled floating-point operations on platforms where SSE is always available (including x86_64 platforms). A related change is the interning of literal numbers, strings, byte strings, characters, and regexps that appear in code and syntax objects. > - deprecation note for ActiveX part of MysterX * MysterX's ActiveX support is deprecated and will be removed in the next release. MysterX's core COM functionality will become deprecated in the next release, but COM functionality will be supported for the foreseeable future as a compatibility layer over a forthcoming `ffi/com' library. > - OS X build defaults to the platform it is built on (i386 vs x86_64) > - Add a tutorial to the FFI overview > - racket/class: send/keyword-apply, dynamic-send > - generalized gcd, lcm to rationals > - syntax/datum, datum-case, etc > - improve choice-evt complexity > > - racket/draw > - generalized brush transform to apply to stipple > - racket/draw: generalize "face" in font% to be description > - added text-outline to dc-path These all seem too minor to me. The OS X build change is almost worth noting, but most OS X users surely download a pre-built installation, and the build change is not relevant to those users. _________________________ Racket Developers list: http://lists.racket-lang.org/dev
