% V3.22 -Removed \usepackage{calc}
% -Corrected \@STRT placement to not inadvertantly force a \mathop
% on rows beginning with a minus sign.
+% V3.23 -Made EOL-separated stacks (i.e., \Longstack, \Shortstack,
+% \Centerstack, \Vectorstack, etc.) work properly when a single
+% (unstacked) row is input.
+% -Noted in documentation that while EOL-separated stacks
+% ignore leading/trailing spaces in their arguments (unless the
+% EOL itself is a space token), the \stackon / \stackunder
+% family of macros do not ignore spaces in their arguments.
+% -Reinstated \usepackage{calc} (Oops!)
