 This file records noteworthy changes.
 
+1.1.0 (<date>)
+* Removed deprecated macros is_ex_a, is_ex_exactly_a and friends.
+
+Backlog from 1.0.n:
+* Fixed LaTeX output of indexed and matrix objects.
+* Fixed matrix::pow(n) for n==0.
+* "(x+1).subs(x==x-1)" now returns the correct result "x" instead of "x-1".
+* (l)degree(s), coeff(s, n) and collect(s) were extended to accept expressions
+  of any class (except add/mul/ncmul/numeric) for "s". They should even work
+  if "s" is a "power" object, as long as the exponent is non-integer, but with
+  some limitations. For example, you can "collect(a*2^x+b*2^x, 2^x)" to get
+  "(a+b)*2^x", but "degree(2^(3*x), 2^x)" yields 0 instead of 3).
+* Speedup in expand().
+* Faster Bernoulli numbers (Markus Nullmeier).
+* Fixed a bug where quo() would call vector::reserve() with a negative
+  argument.
+* Several small bugfices in code generation, output and documentation.
+
+1.0.2 (19 December 2001)
+* Input parser recognizes "sqrt()", which is also used in the output.
+* divide(a,b,q) only modifies q if the division succeeds; also, divide(a,b,a)
+  works now.
+* Fixed small bug in dummy index renaming which could cause it to not
+  recognize renamable indices in some cases.
+* power::degree() and power::ldegree() throw an exception when encountering
+  a non-integer exponent.
+* Add output-support for Python bindings.
+
+1.0.1 (22 November 2001)
+* Function sqrfree() handles a few more cases now.
+* Class relational has real canonical ordering now.
+* Handle obscene libreadline version numbers when building ginsh.
+
 1.0.0 (6 November 2001)
 * Some internal reorganization resulting in a general speed-up.
 * The last 3 evaluated expressions in ginsh are now referred to with the
