                    Changes in afex Version 0.5-x
                    Released May 2013

    Significant User Visible Changes and New Features

    o   added argument factorize (default: TRUE) to aov.car and ez.glm:
		all variables are now factorized per default. (now it is 
		necessary to set factorize=FALSE for ANCOVAs!)
    
    o   added argument per.parameter to mixed() which allows to specify
		variables for which each parameter is tested (not only the 
		overall effect). Can be useful to test for ordered factors. 
		(only implemented for "Type 3" tests)
	
	o	added more informative startup message (thanks to Robert Volcic 
		and Lars Konieczny)
		
	o	mixed, ez.glm and aov.car now check for correct contrasts and set 
		factors to contr.sum if other contrasts are found (can be tunred 
		off via check.contrasts argument). Resetting the default contrast
		to contr.treatment should therefore not interfere with afex.
        (this is not intensly tested, so please report anything)
	
	o	mixed checks numeric variables if they are centered on 0 (and
		gives warning if not).
    
    Bugfixes
    
    o   checks if observed variable is in the data and throws
        an error if not (nice.anova)

                    Changes in afex Version 0.4-x
                    Released February 2013

    o   added generalized and partial eta-squared effect
        sizes to nice.anova (this also included adding
        observed arguments to aov.car, ez.glm, nice.anova)        
    
    o   added new return arguments to aov.car and ez.glm
        (nice, lm, data).
    
    o   changed default return value of aov.car and ez.glm
        to "nice" which now returns a nice ANOVA table
        (nice.anova)
    
    o   mixed has method = "PB" for obtaining parametric
        bootstrapped p-values (e.g., for GLMMs)
        
    o   added alternative argument to compare.2.vectors.
    
    o   aov.car (and ez.glm) now give a warning if 
        observations are missing on within-subject factors.
        (As before, cases with missing values are simply
        excluded from the analysis)
    
    o   had to disable saving of the previous contrasts and
        resetting those after detaching afex due to 
        CRAN policies (no assignment in global environment).
    
    Bugfixes
    
    o   Bug when running mixed() inside a function and
        handing the data.frame over as an argument fixed
        (thanks, again, to Florent Duyme). See
        bugs/eval.scoping.bug.R
    
    o   nice.anova did not work with a model with only one 
        within-subjects factor.

                    Changes in afex Version 0.3-x
                    Released August/September 2012

    Significant User Visible Changes and New Features
    
    o   added function compare.2.vectors().
    
    o   Name of function univariate() changed to univ(), as
        a function with this name is part of package multcomp.
        This may leed to problems. Thanks to Florent Duyme for
        spotting this.
    
    o   added return argument to aov.car() and ez.glm().
    
    o   added rather dubious Type 2 tests to mixed().
    
    o   aov.car checks if each id is only present in one
        cell of the between subjects design.
    
    Bugfixes
    
    o   aov.car now uses do.call when calling lm() to avoid local
        variables in the call to lm() which could led to problems when
        working with the lm model.
    
    o   mixed() now passes ... (further arguments to lmer) correctly.
        (Now mixed uses match.call and eval on the call instead of 
        invoking lmer directly.)
    
    o   corrected bug that was introduced by pbkrtest v3.2 when 
        invoking the print method to an object of class mixed 
        (again thanks to Florent Duyme for spotting this).
    
    o   removed bug when factor levels of within-subject factors
        were non-legal names (solution uses make.names).
