+
+	* evolve.c (gsl_odeiv_evolve_apply): notify user of step-size
+	which caused any failure by returning it
+
+2006-06-13  Brian Gough  <bjg@network-theory.co.uk>
+
+	* gsl_odeiv.h, control.c (gsl_odeiv_control_hadjust): change y0 to

+
+2004-12-01  Brian Gough  <bjg@network-theory.co.uk>
+
+	* updated all solvers to ensure correct handling of error codes
+	from user defined functions
+
+	* test.c (rhs_xsin): added a test which includes failures of the
+	function itself and jacobian
+
+2004-11-25  Brian Gough  <bjg@network-theory.co.uk>
+
+	* gear2.c (gear2_alloc): added check for non-allocation of primer,
+	and two-step error estimation

+
+	* gear1.c (gear1_apply): use 90% error bound
+
+	* rk2imp.c (rk2imp_apply): use 90% error bound
+
+	* rk2simp.c (rk2simp_apply): use 90% error bound
+
+2004-11-18  Brian Gough  <bjg@network-theory.co.uk>
+
+	* test.c: new test program (Tuomo Keskitalo)
+
+2004-11-12  Brian Gough  <bjg@network-theory.co.uk>
+
+	* evolve.c (gsl_odeiv_evolve_apply): check for internal stepper
+	failure (Tuomo Keskitalo)

+
+	* gear1.c rkf45.c rkck.c rk8pd.c rk4imp.c rk2imp.c rk2.c rk4.c:
+	fix error estimate, exact derivatives on output (Tuomo Keskitalo)
+
+2004-05-28  Brian Gough  <bjg@network-theory.co.uk>
+
+	* bsimp.c (bsimp_apply): fix prototype of function to match

+
+Sat Aug  3 19:02:37 2002  Brian Gough  <bjg@network-theory.co.uk>
+
+	* cscal.c (struct): use matlab style error control, with scalar
+ 	relative error and vector absolute error
+
+Wed Oct  3 13:19:28 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* evolve.c (gsl_odeiv_evolve_apply): report error if step
+ 	direction does not match interval direction
+
+	* cstd.c (std_control_hadjust): allow for negative step-sizes
+
+	* evolve.c (gsl_odeiv_evolve_apply): allow for integrating
+ 	backwards in time
+
+Sat Sep 29 21:02:36 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* bsimp.c: use the condition |D^-1 Delta| >> 1 to detect
+ 	singularities, as described in the paper and implemented in METAN1
+ 	by Deuflhard et al.
+
+	* evolve.c (gsl_odeiv_evolve_apply): reset the final_step flag
+ 	whenever the step size is decreased
+
+Sun Jul  1 22:42:02 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* bsimp.c: modified to use new-style vector views
+
+Fri Jun 22 11:59:24 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* evolve.c: keep track of failed step count
+
+Tue Jun 12 11:34:23 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* rkf45.c: added Runge-Kutta Fehlberg method, RKF45
+
+	* reorganized to use standard gsl conventions
+
+Mon Apr 23 10:26:22 2001  Brian Gough  <bjg@network-theory.co.uk>
+
+	* unified error handling conventions to _e for error handling
+ 	functions and no suffix for plain functions, so _impl functions
+ 	are no longer needed.
+
+	* removed tests for EFAULT, since EFAULT should only apply to
+ 	invalid non-null pointers.
+
+2000-05-14  Steve Robbins  <steve@nyongwa.montreal.qc.ca>
+
+	* Makefile.am (test_LDADD): put libgslpermutation ahead of
+	libgslvector in the link beccause the former uses
