 % tabstackengine initial release
 %
 % THIS MATERIAL IS SUBJECT TO THE LaTeX Project Public License
 %
-% V1.00 - Adopted beta version 0.21 as initial release version 1.0
+% V1.00 -Adopted beta version 0.21 as initial release version 1.0
+% V1.10 -Corrected unary/binary problem for left end of tabbed cell content;
+%       -Added \TABunaryLeft (\TABbinaryRight) for "   cell{} ";
+%        added \TABunaryRight (\TABbinaryLeft) for " {}cell   ";
+%        added \TABbinary                      for " {}cell{} ";
+%        The default is \TABunaryLeft (V1.00 wrongly equivalent to \TABbinary)
+%        This removes need to brace unary negatives at lead of cell.
+%       -Corrected bug of trailing \frac, noted in V1.00, by adding a
+%        \relax to definition of \@postTAB in \readTABrow.
