+2013-01-27 Tuomo Keskitalo <tuomo.keskitalo@iki.fi>
+
+ * msbdf.c: Corrected bug which enabled order to be changed
+ by two (first by stability enhancement, then by order evaluation
+ after a rejected step). Thanks for Frantisek Kluknavsky and
+ Andreas Schwab for bug reports!
+
+ * msbdf.c: Added more state variables explicitly to be reset in
+ msbdf_reset.
+
+ *msbdf.c: Added abscorscaled to remove division of abscor for
+ use in msbdf_eval_order and subsequent backwards multiplication.
+
+ *test.c: test_extreme_problems: Increased ringmod case tolerances
+ from 1e-7 to 1e-12 to increase precision. Because that
+ increases computational burden, I also decreased end time
+ from 1e-3 to 1e-5. That decreased the acidity of the test
+ significantly, but the test case is now more appropriate
+ for normal "make check". Thanks for Frantisek Kluknavsky
+ for pointing out bad design of the test case.
+
+2012-09-10 Rhys Ulerich <rhys.ulerich@gmail.com>
+
+ * test.c: Correct two out-of-order declarations.
+ Thanks to Brian Gladman for spotting the problem.
+
+2012-03-10 Tuomo Keskitalo <tuomo.keskitalo@iki.fi>
+
+ * driver.c: Added function gsl_odeiv2_driver_reset_hstart to
+ allow resetting step size, possibly change its sign, too.
+ Check for non-zero hstart in initializations.
+
+ * test.c: Modified test_driver to carry out tests with all
+ steppers. Small printout changes.
+
+2012-01-21 Tuomo Keskitalo <tuomo.keskitalo@iki.fi>
+
+ * rkf45.c: Bug correction: Set gives_exact_dydt_out to 1 in
+ rkf45_type
+
+2012-01-14 Tuomo Keskitalo <tuomo.keskitalo@iki.fi>
+
+ * evolve.c: Modified initial derivative evaluation in evolve_apply
+ to reuse previously calculated values. This saves calls to the
+ user function. Thanks for Illes Farkas for pointing out redundant
+ function calls!
+
+2011-06-28 Brian Gough <bjg@network-theory.co.uk>
+
+ * rk4imp.c (rk4imp_apply): use M_SQRT3 instead of sqrt(3) in array
+ initialiser.
