2021-03-12
	* version 0.15
	* new: option `algebraicN` (infix notation for number of output points)
	added; input for N silently converted to integer for robustness

2019-03-25

	* fix: imprecise t_out calculation
	* new: option `dt0' and user command \pstODErestoreState added
	* change: user command \pstODEsetOrRestoreState removed

2017-06-16
	* version 0.10
	* more diagnostic terminal output for stepsize underflow

2017-06-14
	* version 0.9
	* fix: occasional failure of the stepping routine (zero relative error)

2017-06-12
	* version 0.8
	* fix: Integration step size underflow doesn't lead to ps2pdf crashing
	anymore. Integration of the ODE(s) just stops prematurely.
