The first widely distributed version of Xy-pic was version 2
(from release 1.40 to release 2.6). A special
compatibility mode is used automatically if the
old style of loading is used (using files named xypic.tex
and xypic.sty
). You can also mix old and new diagrams in a
document if you load as described in section 1.1 and
add the declaration \xyoption{v2}
. This provides almost full
backwards compatibility: the following are the only known exceptions:
- Automatic `shortening' of arrow tails by
|
<<
break was a bug
and has been `fixed' so it does not work any more. Fix: Put a
|
<\hole
break before it as described in section 2.3.
- The release 2.6
*
position operator is not available.
Fix: Use the :
and ::
operators (described in detail in
the reference manual [8]).
- Using
as the target of an arrow command does
not work. Fix: Enclose it in braces, i.e., write
.
- The old
\pit
, \apit
, and \bpit
commands are not
defined. Fix: Use *@{>}
(or \tip
) with variants and
rotation.
- The even older notation where an argument in braces to
\rto
and the
others was automatically taken to be a `tail' is not supported.
Fix: Use the supported |
<
... notation.
Finally note that sometimes the spacing with version
is
`improved' relative to earlier versions
. Please report all
other things that do not work the same in version 2.6 and
to the author.
