VERSION 1.1-2

    - CHANGED: minor changes and updates to documentation
    - CHANGED: minor changes and updates to glossary of CCM terms
    - FIXED  : minor bug in function 'submodels' caused error when testing whether 
               an expression whose antecedent consisted of a single condition 
               contained redundant elements (thanks to Michael Baumgartner)
    - NEW    : function 'randomDGS' has been enhanced with three new arguments 
               'prob', 'diversity' and 'delete.trivial' for finer control

VERSION 1.1-1

    - CHANGED: minor updates to documentation
    - CHANGED: minor updates to glossary of CCM terms
    
    
VERSION 1.1-0

    - CHANGED: minor updates to documentation
    - CHANGED: minor updates to printing functions
    - CHANGED: use of lower-case letters in factor names and the outcome caused 
               error message in functions 'eQMC' and 'truthTable'; these functions 
               now return a warning but proceed by transforming to upper-case letters
    - CHANGED: object class 'sS' and associated print function 'print.sS' removed
    - FIXED  : bug in function 'submodels' returned too few models when
               provided a solution object of class 'qca' with a negated outcome,
               and an incorrect error message when provided a model with a 
               negated outcome as a string
    - NEW    : extensive glossary of QCA/CNA terms added (co-authored with Michael 
               Baumgartner)
    - NEW    : function 'ambiguity' for analyzing the extent of model ambiguities
               across a variety of QCA designs (including verification function 
               'verify.ambig')
    - NEW    : function 'randomDGS' for random generation of data-generating
               structures (QCA models)
    - NEW    : dataset 'd.tumorscreening'
    

VERSION 1.0-0
  
  o launch version: main changes to predecessor package 'QCA', version 1.1-4:
    
    - RENAMED: function 'allExpressions' to 'implicantMatrix', 'createMatrix' to 
               'mintermMatrix', 'deMorgan' to 'DeMorgan', 'eqmcc' to 'eQMC'
    - RENAMED: argument 'conditions' in functions 'eQMC', 'truthTable', and 
               'superSubset' renamed to 'exo.facs' (exogenous factors)
    - RENAMED: argument 'include' in function 'eQMC' to 'sol.type' (solution type)
    - RENAMED: argument 'explain' in function 'eQMC' to 'minimize'
    - RENAMED: argument 'prod.split' in functions 'DeMorgan' and 'factorize' to
               'and.split'
    - CHANGED: functions 'demoChart', 'findSubsets', 'findSupersets', 'getRow', 
               and 'solveChart' removed from user level (internalized)
    - CHANGED: error messages corrected and extended in verification functions 
               'verify.data', 'verify.tt', 'verify.qca', 'verify.dir.exp', 
               'verify.mqca', and 'verify.inf.test'
    - CHANGED: all documentation files revised and updated
    - CHANGED: default value for argument 'min.dis' in function 'eQMC' set to 
               'TRUE'
    - CHANGED: default value for argument 'sol.type' in function 'eQMC' set to 
               'ps' (parsimonious solution)
    - CHANGED: truth table not printed any more when dataset is passed directly 
               to function 'eQMC' and argument 'details' is set to 'TRUE' 
    - FIXED  : bug in functions 'truthTable' and 'eqmcc' (new 'eQMC') produced
               incorrect truth table for outcomes from multivalent factors when
               these outcomes included levels with two or more digits
    - FIXED  : bug in function 'eqmcc' ('eQMC') in relation to intermediate solutions
    - FIXED  : use of argument 'inf.test' in function 'truthTable' caused error 
               when argument 'complete = TRUE'
    - FIXED  : argument 'data' in function 'eqmcc' (new 'eQMC') caused error when 
               'data' was of class 'matrix' instead of 'data.frame' or 'tt'
    - FIXED  : error messages for argument 'data' with respect to missing values 
               restricted to data under factor frame (argument 'exo.facs' plus 
               factor of argument 'outcome') instead of all data under argument 
               'data' (caused error message)
    - FIXED  : function 'eqmcc' (new 'eQMC') used original factor labels when
               passed an object of class 'tt' although argument 'use.letters'
               was set to 'TRUE' in call to function 'truthTable'
    - FIXED  : function 'print.qca' used incorrect ordering of models in multi-
               model solutions when argument 'relation' was set to 'sufnec' in call
               to function 'eqmcc' (new 'eQMC')
    - NEW    : functions 'limitedDiversity', 'implicIndep', 'retention', 'submodels' 
               and 'testTESA' for purposes of method evaluation
    - NEW    : function 'submodels.loop' (internal)
    - NEW    : information in documentation files on contributors (categories: 
               development, documentation, programming, testing)
