-Version 0.94 of breqn.sty (May 2002) has a small patch to fix a bug that
-shows up when (a) flexisym is not explicitly loaded before breqn and (b)
-breqn is not loaded with the "mathstyleoff" option.
-
-This version of breqn.sty is not intended to be the official beta
-release because group alignment and the darray environment remain
-insufficiently addressed.
-
-In version 0.93 (September 2001) I tracked down and eliminated a number
-of significant bugs in the single-equation cases.
-
-I also added a mathstyle package (called from flexisym.sty) that
-activates ^ and _ to eliminate problems from sub/sup objects that appear
-from the user's point of view to be atomic but that from TeX's math atom
-point of view are composite. It appears to me that this will become
-inevitable at some point down the road and therefore it is better to
-start with it now so that some of the compatibility problems with other
-packages can begin to be addressed. For starters, after the mathstyle
-package is loaded, any subsequently loaded package that uses characters
-such as ^^J or ^^M will tend to run into trouble. A mathstyle-aware
-package will (a) need to save/restore the catcodes of ^ and _, and (b)
-use \mathsub and \mathsup if it has any definitions that require sub or
-sup operations. (I have a separate package "pcatcode" in the works that
-provides facilities to help with this, since the catcode problem is a
-more general problem already in need of a solution for many other
-packages, e.g., amsmath (double-quote character); but pcatcode isn't
-quite ready for release yet.)
-
-For the time being you will probably want to load flexisym & breqn after
-other packages, as much as possible.
-
-What I'm currently using in my test files is along the lines of
-
- \usepackage[cmbase]{flexisym}
- \usesymbols{msabm}
- \usepackage[debug]{breqn}
- \setkeys{breqn}{compact}
-
-You can turn off the active catcodes of ^ and _ by using a
-"mathstyleoff" option:
-
- \usepackage[mathstyleoff,cmbase]{flexisym}
-
-In breqn094b.zip I have also included a couple of dvi files documenting
-to some extent the algorithms that I am trying to implement.
