* Web Server --- backwards incompatible change that prevents X-expressions and lists of bytes from being directly returned from servlets. This will increase performance for those types of responses and allow easier experimentation with response types. Please read "PLTHOME/collects/web-server/compat/0/README" to learn about porting your servlets forward. Don’t worry. It’s easy.
2011/2/9 Matthew Flatt <mfl...@cs.utah.edu>: > Let's get the ball rolling on the release announcement. Here are draft > bullets for the drawing and GUI libraries: > > * The `racket/draw' library --- which implements the drawing half the > GUI toolkit --- is a new implementation built on top of the Cairo > drawing library and the Pango text-rendering library. > > The `racket/draw' library can be used independent of the > `racket/gui/base' library and without a graphics display (e.g., > without an X11 connection). > > The new library has one small incompatibility with the old GUI > toolbox: 'xor drawing is no longer supported. The new library has > many additional features: rotation and general affine > transformations, PDF and SVG drawing contexts, gradients, and > alpha-channel bitmaps. > > * The `racket/gui/base' library is a new implementation built on top > of Win32 under Windows, Cocoa (instead of Carbon) under Mac OS X, > and Gtk (instead of Xt) under Unix/X. > > Unix/X users will see the biggest difference with this change. > DrRacket and all Racket GUI programs take on the desktop theme for > menus, buttons, and other GUI widgets. > > The GRacket executable is no longer strictly necessary for running > GUI programs, because the `racket/gui/base' library can be used from > Racket. To the degree that a platform distinguishes GUI and console > applications, however, the GRacket executable still offers some > additional GUI-specific functionality (e.g., single-instance > support). > > The new library includes small incompatibilities with the old GUI > toolbox: the `send-event', `current-ps-afm-file-paths', and > `current-ps-cmap-file-paths' functions have been removed. The > `racket/gui/base' library re-exports `racket/draw', so it includes > the same drawing functionality as before (except for 'xor drawing). > > _________________________________________________ > For list-related administrative tasks: > http://lists.racket-lang.org/listinfo/dev > -- Jay McCarthy <j...@cs.byu.edu> Assistant Professor / Brigham Young University http://faculty.cs.byu.edu/~jay "The glory of God is Intelligence" - D&C 93 _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
