Changes in BB version 2011.2-1 

	o Added an additional stopping criterion.  Now, the iterations 		are stopped when function value does not change by more 		than `ftol' between successive iterations. 
		Default is ftol = 1.e-14 

Changes in BB version 2010.7-1 
	   
   o	Added function projectLinear, and adjusted spg arguments
   	to facilitate this by adding projectArgs. Arguments lower and upper for
	spg provide a simplified way to specify these elements of the projectArgs
	list for box constraints. Also, the value of the spg argument project 
	must now be indicated as a character string.

   o	Corresponding changes for projectArgs were made to BBoptim.

   o	Added projection examples.

   o	Added fix to spg for some cases when the best value does not get 
   	properly returned.

   o	Added fix to BBoptim to indicate error in case were all calls to spg 	
   	failed (but were caught by try and ignored).

   o	Fix sign of printed value (trace=TRUE) on initial iteration of spg 
   	maximization problem.

Changes in BB version 2010.5-1 
	   
   o	Changed BBsolve to avoid using Nelder-Mead in one dimensional problems
	(because the warning message is confusing).

   o	Adjusted test tolerances for 64 bit Windows platform.

Changes in BB version 2010.4-1 
	   
   o	Added argument quiet=FALSE to several functions, to be able to suppress
	warnings and some output.
	   
   o	Added a test of spg for the case when optimum values are supplied as 
	initial values (thanks to John Nash).
	   
   o	Fixed a bug in spg when optimum values are supplied as initial values.

   o	Standardized NEWS format for new function news().

Changes in BB version 2009.9-1 
	   
   o	Added BBvignetteJSS of JSS paper, and small related changes, including
	license to GPL-2 or greater.
  
   o	Relaxed multiStartHDP.R test for CRAN Mac testing platform.

   o	Added Fleishman example to the vignette tutorial.

  
Changes in BB version 2009.06-2 
  
   o	Added try() wrapper in BBoptim and BBsolve calls from multiStart().  


Changes in BB version 2009.06-1 
  
   o	Added function multiStart to start BBoptim or BBsolve from multiple
	initial points.  

   o	Added BBoptim wrapper function. The wrapper functions BBoptim and 
 	BBsolve are the preferred user interface.  

   o	Added checks in sane() and dfsane() for an objective function returning 
	a non-vector result.  
  
   o	Added a check to spg() that a user supplied gradient gives a result close
 	to grad from numDeriv (which means numDeriv is now required).  

   o	Added check in spg() for an objective function returning a non-scalar 
 	result, with an automatic fix if the result is length 1.  

   o	In nlsolve demo nsim was reduced from 100 to 20 and in nlmin demo the 
 	optim examples were commented out because of testing time 
	constraints on CRAN.
 
   o	Added BBsolve wrapper function.  

   o	Minor documentation fixes found by the new parser in R-devel.


Changes in BB version 2008.11-1
  
   o	"eps" decreased to 1.e-10 (from 1.e-08) in sane, to be consistent 
	with "eps" for dfsane.

   o	Nelder-Mead start option for poor starting values in sane and dfsane.

   o	Steplength for first iteration was re-scaled in sane and dfsane.

   o	Retard scheme is introduced close to solution in sane and dfsane.

   o	A new stopping criterion "noimp" is introduced (flag=4 in sane, 
	flag=3 in dfsane).

   o	"optim" can be invoked using "L-BFGS-B" when "sane" is unsuccessful 
	(type = 4 or 5) by setting BFGS of the control list in the 
	sane arguments.

   o	"optim" can be invoked using "L-BFGS-B" when "dfsane" is unsuccessful 
	(type = 2 or 5) by setting BFGS of the control list in the 
	dfsane arguments.
 
   o	"pbest" and "normF.best are now returned from sane and dfsane.


Changes in BB version 2008.8-1
  
   o	fixed bug in sane and spg (previously fixed in dfsane) when tol is 
	already ok initially and while loop is skipped, so flag in result is 
	not set. Also added a warning message when this happens.


Changes in BB version 2008.7-1
  
   o	fixed bug in dfsane when tol is already ok initially and while loop is
	skipped, so flag in result is not set.

Changes in BB version 2008.5-1
  
   o	fixed a references that was inaccurate and added web links to others.

   o	fixed bug when maximizing a function with analytic gradient supplied, 
	and add a test of this.

   o	changed the title (as appears on CRAN) to be more descriptive.


Changes in BB version 2008.4-1

   o	first release
