+0.8.2 (<date>)
+* degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() work with
+  non-symbols as the second argument in ginsh.
+* the argument to collect() can be a list of objects in which case the
+  result is either a recursively collected polynomial, or a polynomial in
+  a distributed form with terms like coeff*x1^e1*...*xn^en, as specified by
+  the second argument to collect().
+
+0.8.1 (16 April 2001)
 * degree(), ldegree(), coeff(), lcoeff(), tcoeff() and collect() can now
   be used with constants, functions and indexed expressions as well, so you
   can use it to collect by powers of Pi or sin(x), or to find the coefficient
