* XEmacs 21.4.16 Withdrawn Due to a critical problem in parsing shy groups in regular expressions, The XEmacs Team is withdrawing Release 21.4.16. The defect in question can lead to infinite loops and/or unexplained crashes in XEmacs. See, for example: http://list-archive.xemacs.org/xemacs-beta/200412/msg00195.html , http://list-archive.xemacs.org/xemacs-beta/200412/msg00314.html and http://list-archive.xemacs.org/xemacs-beta/200502/msg00076.html . The XEmacs 21.4.16 tarballs will be removed from their current location at ftp://ftp.xemacs.org/pub/xemacs/xemacs-21.4, effective immediately. XEmacs 21.4.17 will be released on February 6, 2005. If, for some reason, you must run XEmacs 21.4.16, please apply the patch found in ftp://ftp.xemacs.org/pub/xemacs/xemacs-21.4/withdrawn/Urgent_patch_for_21.4.16 then rebuild and reinstall XEmacs. The XEmacs Team regrets any inconvenience. Sincerely, Vin Shelton Release Engineer for Stable XEmacs February 4, 2005
