Dear Racket users, Many of you noticed that DrRacket v5.2.1 refused to launch today, March 26. We sincerely apologize for this inconvenience.
The problem is due to a so-called "Easter egg", which is a visual surprise that one developer builds into the code for the others and our users -- a tradition going back to the early days of our project. The bug affects only DrRacket, no other Racket software. As far as version 5.2.1 is concerned, the bug will disappear tomorrow, but it will return later this year. For the upcoming release -- due out before the next "easter egg" date -- we will either install much more reliable test methods for the Easter eggs or we will remove them entirely. We intend to make a fixed version of 5.2.1 available later today. In the meantime, we offer the following workarounds for the DrRacket bug: * Revert to version 5.2: http://download.racket-lang.org/racket-v5.2.html * In your current installation of 5.2.1, navigate to the following folder: collects -> drracket -> private remove the file drracket-normal.rkt and replace it with the corrected copy at http://www.cs.utah.edu/plt/fix/drracket-normal.rkt * For those of you with commandline tool experience, download a Racket patch file from http://www.cs.utah.edu/plt/fix/patch-for-v5.2.1.plt navigate in your shell to the folder with the 5.2.1 executables, and install the patch with ./raco setup -A .... where .... specifies a path to the downloaded file. As much as we prepare and test these Easter eggs, software obeys only one law: what can go wrong will go wrong eventually. We definitely should have been more careful. Once again, we regret any problems we caused you today -- Matthias Felleisen, for PLT ____________________________ Racket Announcements list: http://lists.racket-lang.org/announce
