                      Changes in version 2022.9-1                       

    o   Changed license from GPL-2 to GPL >= 2.

                      Changes in version 2020.2-1                       

    o   Fixed Rbuildignore so that files from building vignettes are 
	 	not omitted in the package build.	

    o   Added German translation of messages (provided by  Chris Leick).

    o   Added Korean translation of messages (provided by Chel Hee Lee).

                Changes in version 2016.8-1 (2016-08-27)                

    o   simplification of hessian.default() call to jacobian() and grad()
		in the case of method 'complex' (pointed out by Andreas Rappold).

    o   added argument 'side=NULL' in the hessian.default() call to jacobian()
		and grad() in the case of method 'complex' to ensure proper passing 
	of ... arguments to the function for which the hessian is being
	calculated (pointed out by Andreas Rappold).

                Changes in version 2014.2-1 (2015-05-04)                

    o   added argument 'side' to allow one-sided first derivatives (grad and 
		jacobian) for simple and Richardson  methods. 

    o   minor documentation improvements. 

                      Changes in version 2013.2-1                       

    o   updated R dependency from 1.8.1 to 2.11.1 because of complex step
		derivative dependency on a fix to exponentiation with integers (pointed
	out by Hans W. Borchers).

    o   added flag in DESCRIPTION to ByteComple.

                Changes in version 2012.9-1 (2012-10-14)                

    o   added complex step derivatives (from Ravi Varadhan) and related tests.

    o   changed method.args to an empty list in the default methods, as the real
		defaults depend on the approximation, and are documented in details.

                Changes in version 2012.3-1 (2012-03-27)                

    o   no real changes, but bumping version for new CRAN suitability check.

                      Changes in version 2011.11-2                      

    o   fixed genD documentation error for denominator in f" (d^2 rather 
		than 2*d noticed by Yilun Wang)

                      Changes in version 2011.11-1                      

    o   updated maintainer email address.

               Changes in version 2010.11-1 (2011-01-20)                

    o   Added warning in the documentation regarding trying to pass arguments
		in ... with the same names as numDeriv function arguments.

                      Changes in version 2010.2-1                       

    o   Added more graceful failure in the case of NA returned by a function
	(thanks to Adam Kramer).

                      Changes in version 2009.2-2                       

    o   Standardized NEWS format for new function news().

                Changes in version 2009.2-1 (2009-02-05)                

    o   argument zero.tol was added to grad, jacobian and genD, and is used to 
	test if parameters are zero in order to determine if eps should be used
	in place of d. Previous tests using == did not work for very small values.

    o   defaults argument d to grad was 0.0001, but specification made it 
		appear to be 0.1. Specification was changed to make default clear.

    o   unnecessary hessian.default argument setting was removed (they are 
	just passed to genD which duplicated the setting).

    o   Some documentation links to [stats]numericDeriv mistakenly called 
	numericalDeriv were fixed.  

                Changes in version 2006.4-1 (2006-04-11)                

    o   First released version.
