 0.8.4 (<date>)
 * simplify_indexed() renames dummy indices so, e.g., "a.i*a.i+a.j*a.j" gets
   simplified to "2*a.i*a.i".
+* Added canonicalize_clifford() function that can be helpful when comparing
+  expressions containing Dirac matrices.
 * Fixed possible crash when calling subs() on expressions with non-commutative
   products.
