Racket version 5.1 is now available from http://racket-lang.org/ The most significant change in version 5.1 is a rewrite of the GUI library: http://blog.racket-lang.org/2010/12/racket-version-5.html Unix/X users will see the biggest difference with this change, because DrRacket and all Racket GUI programs now take on the desktop theme for menus, buttons, and other GUI widgets. In the long run, Racket GUI programs on all platforms will improve as a result of the library rewrite. In the short run, beware that this first release of a new library will inevitably include a new set of bugs. Version 5.1 changes in more detail: * The `racket/draw' library --- which implements the drawing half the GUI toolkit --- 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 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 `racket/gui/base' 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). * The new `racket/snip' library can be used independently of `racket/gui/base' to work with graphical editor content (e.g., images in student programs). Like `racket/draw', the `racket/snip' library is re-exported by `racket/gui/base'. * The Web Server includes a backwards incompatible change that prevents X-expressions and lists of bytes from being directly returned from servlets. This change will increase performance for those types of responses and allow easier experimentation with response types. Please see "collects/web-server/compat/0/README" in the installation to learn about porting your servlets forward. Don't worry. It's easy. * The new `raco demodularize' tool collapses a module's dependencies into a single module comprising the whole program. This transformation currently provides no performance improvement, but is the basis for cross-module optimization and dead-code elimination tools to come. The transformation is currently useful for static analysis of whole Racket programs. * The picturing-programs teachpack, formerly installed via PLaneT, is now bundled with the standard distribution. Use the teachpack with `(require picturing-programs)' instead of `(require installed-teachpacks/picturing-programs)'. The old PLaneT-based installation procedure still works, but it now merely installs a stub that invokes the bundled version. * Slideshow picts, `racket/draw' bitmaps, and images created with `2htdp/image' can now be used directly in Scribble documents. More generally, the new `file/convertible' protocol enables any value that is convertible to a PNG and/or PDF stream to be used as an image in a Scribble document. * The Same game sports a new look and an improved scoring system.

Re: [racket-dev] drafting the v5.1 release announcement
Here's a new draft that folds in the contributions so far --- all edited to varying degrees. I left out `racket/snip', because it seems relatively obscure. Racket version 5.1 is now available from http://racket-lang.org/ The most significant change in version 5.1 is a rewrite of the GUI library: http://blog.racket-lang.org/2010/12/racket-version-5.html Unix/X users will see the biggest difference with this change, because DrRacket and all Racket GUI programs now take on the desktop theme for menus, buttons, and other GUI widgets.

I don't think any of these are important enough to go into a release announcement. One's a (very minor) contract combinator addition and the other is pretty much just details of the particular implementation.

I think that you have the right idea John. I think that I'd write something like this (the difference I want to make is "less stable" and adding the link to the blog post; the other stuff is just random words). * The most significant change in this release (and the most significant change in Racket/PLT Scheme history) was a rewrite of the low-level GUI library. While things are relatively stable, there are likely to still be kinks to work out so this release is probably going to be less stable than usual.

I looked over the commits I've pushed between 5.0.2 and 5.1, and I don't see anything worth including in the release notes.

[racket-dev] drafting the v5.1 release announcement
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
