# * RELEASE HISTORY OF THE 'mitml' PACKAGE:
--

# Version 0.3-3 (2016-07-04)
--

* jomoImpute:      added features (support for imputation of cluster-level
                   variables, i.e., the two-level procedures "jomo2...")

* print/summary:   revised appearance in two-level models (model summary is
                   displayed separately by level for two-level imputation
                   procedures)

* plot:            additional value for print argument ("beta2", denoting the
                   regression coefficients of the cluster-level imputation
                   model)

* jomoImpute:      bugfix (fixes error in the usage of starting values in cases
                   with only continuous/no categorical data)

* plot:            revised formatting of the plot title (order of variables)

# Version 0.3-2 (2016-05-10)
--

* plot:            added features (requesting single parameters, thinning of 
                   the chain prior to plotting)

* summary:         added features (summary of autocorrelation)

* plot:            revised appearance and behavior (burn-in printed in grey,
                   included Rhat and autocorrelation at lag k in the posterior
                   summary; for trace="burnin", the summary is now calculated
                   for the burn-in phase, not the imputation phase)

# Version 0.3-1 (2016-05-10)
--

* anova:           new function based on objects of class 'mitml.result',
                   facilitating comparisons for a sequence of models

* long2mitml.list: new function, converting multiple imputations from "long"
                   format to 'mitml.list'

* jomo2mitml.list: new function, converting imputations generated byt the 'jomo'
                   package to 'mitml.list'

* multilevelR2:    new function, calculating measures of explained variance
                   (R^2) for multilevel models and based on observed or multiply
                   imputed data sets

* justice:         new data set, including re-simulated data based on the study
                   of procedural justice, justice climate, and organizational
                   satisfaction by Liao and Rupp (2005)

* plot:            renamed export directory ("mitmlPlots", formerly "panPlots")

* testModels:      added automatic refit using ML for REML fitted models

* mitmlComplete:   bugfix (fixes error with mixed categorical and continuous
                   variables)

* plot:            bugfix (fixes handling of latent background variables for
                   categorical variables)

# Version 0.3-0 (2016-03-15)
--

* jomoImpute:      new function, providing an interface to the jomo package for
                   imputation of missing values at level 1
                   
                   - includes adjustments in mitml.complete as well as the
                     summary, print, and plot methods)
                   - includes minor changes in the interpretation of the formula
                     and type arguments
                   - adds a few slots to the 'mitml' object class

* summary:         bugfix (fixes behavior when applied to fixed parameters
                   with zero variance)

* as.mitml.list:   bugfix (fixes order of class attributes)


# Version 0.2-4 (2015-10-19)
--

* clusterMeans:    code improvements

* panImpute:       code improvements

* testConstraints: added features (model-independent input)

* testEstimates:   added features (model-independent input)

* testModels:      comparisons of REML fits through D2 is now permitted

* summary:         bugfix (n.Rhat now takes effect), added features (goodness
                   of approximation)


# Version 0.2-3 (2015-07-09)
--

* panImpute:       added features (silent mode), bugfix (ordering of variables
                   with nonstandard priors)

* summary:         added features (details on PSR)

* plot:            revised layout, added features (trend line, posterior 
                   summary), bugfix (plot labels)

* testModels:      bugfix (structural zeros in lmer objects)

* studentratings:  renamed variable (data set)


# Version 0.2-2 (2015-05-23)
--

* initial release
