Dear Category Theorists, Please find enclosed a copy of the TRAILER for a new version of Xy-pic - I am sorry for announcing a new version so soon after the previous release but a serious bug needed fixing. I hope you will find this version useful. Sincerely, Kristoffer H. Rose PS. Notice that DIKU has discontinued my ftp directory, so the European home of Xy-pic is now at brics.dk; as usual the mirror at CTAN should be current in a few days. ======================================================================= ANNOUNCING the Xy-pic version 3.5 DIAGRAM TYPESETTING PACKAGE ======================================================================= This is to announce a release of my diagram typesetting package Xy-pic. version 3.5 is a bug fix release where a single serious bug of the previous major release of Xy-pic 3 has been eliminated. ----------------------------------------------------------------------- GENERAL ----------------------------------------------------------------------- Xy-pic is a package for typesetting a variety of graphs and diagrams with TeX. Xy-pic works with most formats (including LaTeX, AMS-LaTeX, AMS-TeX, and plain TeX), in particular Xy-pic is provided as a LaTeX2e `supported package' (following the `CTAN LaTeX2e bundle' standard). Further specifics of the package are in the distribution README file. ----------------------------------------------------------------------- NEWS ----------------------------------------------------------------------- Xy-pic version 3 was a thorough rewrite of the prior major version, version 2 (last version 2 release was release 2.6; several beta-test releases of version 3, numbered 2.7-2.12, were made available to users). However, full backwards compatibility is maintained (except for the unavoidable but fully documented obscure cases). Release 3.5 fixes the following problem of release 3.4: * Breaks (in arrows) were ignored more often than not! Furthermore version 3.5 adds an installation script for TDS-compliant un*x Xy-pic installations. Thanks to Uffe Engberg, Juan Carlos Soliveres, and John Landamore for your bug reports! ----------------------------------------------------------------------- AVAILABILITY ----------------------------------------------------------------------- Xy-pic can be retrieved through the World Wide Web Xy-pic `home pages': URL: http://www.brics.dk/~krisrose/Xy-pic.html URL: http://www.mpce.mq.edu.au/~ross/Xy-pic.html as well as by anonymous ftp from CTAN: macros/generic/diagrams/xypic and from the private archives of the authors: ftp.brics.dk : /Staff/krisrose/TeX/ ftp.mpce.mq.edu.au : /pub/maths/TeX/ Check the README file in each location for specifics, in particular check that you have reached a version 3.5 copy (some archives take a while to mirror the latest files)! ----------------------------------------------------------------------- HISTORY & CREDITS ----------------------------------------------------------------------- The first public release (version 1.40) of Xy-pic was created by Kristoffer H. Rose, DIKU, U of Copenhagen (now BRICS, U of Aarhus) and distributed via Usenet on December 19, 1991. (Version 3.3 was released on December 19, 1996 because this was the fifth anniversary of Xy-pic.) This quickly became Version 2 of which version 2.6 was the most stable. The rewrite that became version 3 is a continued collaboration with Ross Moore, Macquarie U, Sydney, initiated through a visit to Macquarie (Jan-May 1994 supported by the Australian Research Council, Macquarie University, and using donated DEC equipment). Xy-pic is Copyright (c) 1991-1997 by Kristoffer H. Rose and 1994-1997 by Ross Moore under GNU COPYLEFT which means that you can use the package for any purpose but if you provide the macros or any code derived from them to a third party then you are obliged to include the entire Xy-pic package (full details in the file COPYING). ----------------------------------------------------------------------- This is the end of the announcement.
