+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.
