- Dear Xy-pic users,
-
- This is to announce yet another BUG FIX release of my DIAGRAM DRAWING
- PACKAGE, XY-pic: version 2.12. It fixes the following user visible
- bugs in version 2.11:
-
- * No conflict with `AMS-LaTeX' version 1.2 (SEE BELOW).
-
- * No conflict with Karl Berry's `eplain' (SEE BELOW).
-
- * Curves with explicit control are now right [Sjoerd Crans].
-
- * Directional vectors no longer invalidate the Xy-state [Luc van Eycken].
-
- * Tips on zero-sized turns no longer reversed [Jorge Almeida].
-
- * Curves no longer overlap the surrounding text.
-
- * Numerous documentation fixes in the Reference Manual.
-
- * Short steep segments now placed correctly [thanks, Ross].
-
- I am sorry to announce this very interim version which is necessary
- because of a change in an internal function of AMS-LaTeX [sic]. Thus
-
- ** PLEASE UPDATE TO VERSION 2.12 IF YOU USE AMS-LaTeX ***
-
- The release of the `real' version 3 (no longer in beta-test) is
- imminent so you need not update otherwise unless any of the other bugs
- have bothered you (or you desperately need one of the additions
- described below).
-
- There is ONE IMPORTANT CHANGE in the v3 extensions of this version:
- the \arrow command has been renamed to \ar in order to make diagrams
- more concise and avoid conflict with Karl Berry's `eplain', however,
- using the `v2' compatibility option will still define \arrow (as well
- as \stop and \merge that are also in conflict with existing names on
- some systems).
-
- - o -
-
- One extension and one feature have been added with this release:
-
- * \xyoption{cmtip} allows the use of arrow tips that resemble those
- of D. Knuth's Computer Modern and Computer Concrete fonts.
-
- * \xyoption{poly} supports drawing of regular polygons (by Ross Moore).
-
- Version 3 will also have a special input mode for `knots and links'.
