Version 0.10: 2009-06-22

	- new function 'unuran.packed' for packing 'unuran' objects.
          When packed, all information are stored as R lists and allows
	  handling of 'unuran' objects just as ordinary R objects, in
	  particular they can then saved and restored in future R sessions,
	  and they can be copied to other nodes in parallel computing.

	- uq() now also supports method 'DGT' (for discrete distributions).


Version 0.9: 2009-02-26

	- IMPORTANT:

	  Paramters 'lb' and 'ub' (lower and upper bound of domain)
	  do not have default values any more and are obligatory in
	  all functions with these arguments. Thus thee following
	  functions have been changed:

	   o Continuous distributions:
                unuran.cont.new
	        ars.new
	        itdr.new
	        pinv.new
	        srou.new
	        tdr.new
	     If R stops when calling these functions with the error
             message "domain ('lb','ub') missing", then one has to add
             the formerly defaults "lb=-Inf" and/or "ub=Inf" for the
             missing arguments.

	   o Discrete distributions:
	        unuran.discr.new
	        dari.new
	     If R stops when calling these functions with the error
             message "domain ('lb','ub') missing", then one has to add
	     the formerly defaults "lb=0" and "ub=Inf" for the missing
             arguments.

	  We observed a possible pitfall with the former interface.
	  When a user wanted to draw a sample from a distribution with
	  positive domain but forgot to set "lb=0" then it was
	  possible that the generator (silently!) did not work as
	  expected and caused invalid simulation results.
	  Forcing to set the domain reduces this risk.
	  Thus we decided to stay on the safe side.

	  We appologize for this inconvenience.

	- fixed syntax errors and inconsistent formating in Rd files.


Version 0.8: 2008-11-26

        - reorganized functions into three groups:

          * Runuran-Distribution:
            easy-to-use sampling algorithms for particular
            distributions.

	  * Runuran-Universal:
	    interface to a carefully selected collection of UNU.RAN
	    methods with their most important variants.

	  * Runuran-Advanced:
            wrapper to the UNU.RAN string API.

        - improved documentation,
          added vignette

	- new function uq() for computing quantiles approximately.

        - new functions for directly creating generator objects 
          for selected UNU.RAN methods:
    	    ars.new()
	    dari.new()
	    dau.new()
	    dgt.new()
	    hitro.new()
	    itdr.new()
	    pinv.new()
	    srou.new()
	    tdr.new()
	    vnrou.new()

        - new functions for creating UNU.RAN distribution 
          objects: 

  	    unuran.cmv.new(...)    replaces  unuran.cmv()
	    unuran.cont.new(...)   replaces  unuran.cont()
	    unuran.discr.new(...)  replaces  unuran.discr()

          Remark: The default for argument 'islog' has been changed to 
          'islog=FALSE'.

	- deprecated functions:
	     uqhinv()
             urdau()
	     urdgt()	
	     urhitro()
	     urtdr()

        - contains UNU.RAN version 1.3.0


Version 0.7: 2008-04-21

	- print() now shows some information about a generator
          object.

	- new function unuran.details() for printing detailed 
	  information about a generator object.

	- new function uqhinv() for compting quantiles approximately
	  using UNU.RAN method 'HINV'.


Version 0.6: 2007-12-10

        - added slots for a rectangular domain and the center 
          (point in main region of distribution) for multivariate 
          distribution class 'distr.cmv'.

        - new method 'MVTDR' in UNU.RAN.

        - fixed broken optional arguments in routines urtdr() and
          urhitro().

            (The optional arguments were not passed to the given
            density function in contradiction to the help page of
	    these routines.)


Version 0.5: 2007-08-01

	- added S4 classes for distribution objects:

	    This allows to define distributions by means of
	    R functions instead of using the UNU.RAN string API
	    (which is still supported).

	- added support for multivariate distributions.

	- added routine 'urtdr'.


Version 0.4: 2007-05-16

        - First public release.
