Version 0.2.0
--------------------------------------------------------------------------------

* Added arguments probmin and probmax to MinimalInformative in order to control
  the probability threshold at the minimum and maximum dose for the minimally 
  informative prior

* Values of 95% CI and the corresponding ratio of the upper to the lower limit of this CI
  are displayed in results when using 'nextBest'

* The six- number summary tables  including the values of the lowest, 25th percentile,
  50th percentile or the median, the mean, the 75th precentile and the highest of the 
  final (at stopping) estimates of the 
  1) dose levels corresponds to the target probability of DLE used at the end of a trial, TDEOT
  2) ratios of the upper to the lower 95% credibility intervals (CI) of TDEOT
  3) dose levels corresponds to the target probability of DLE used during a trial
  4) dose levels corresponds to the maximum gain value, Gstar
  5) ratios of the upper to the lower 95% CI of the final estimates of Gstar
  6) optimal doses, either the TDEOT (for DLE response only) or the minimum of TDEOT and Gstar 
     (for DLE and efficacy response)
  7) ratios of the optimal dose

  across all simulations will also be displayed when using 'summary' for simulations.
  


Version 0.1.8
--------------------------------------------------------------------------------

* The value of the 95% CI of the final estimates 
  will be displayed in results when using 'stopTrial'  
  
* Bugfixes for dual endpoint designs: 
  - Improved graphical display in plots for nextBest dose 
  - Improved methodology to compute Gstar
  - Warnings are removed when using nextBest in simulations
  - Stopping rules can now also be freely combined using the and/or operators    
    with the dual endpoint design stopping rules not using MCMC samples.

Version 0.1.6
--------------------------------------------------------------------------------

* New model class "LogisticLogNormalMixture" has been added, for use with the 
  new data class "DataMixture".

* New stopping rule "StoppingHighestDose" has been added.

* The "examine" method no longer stops when two consecutive cohorts start with 
  the same dose. This is important e.g. for the two-parts study designs, where 
  part 1 can end with the same dose as part 2 starts.
  
* The contents of the "datanames" slot of new models are no longer restricted to 
  a specific set, which was previously enforced by the validation function of 
  the GeneralModel and AllModels classes.
  
* Sampling from the prior can now be enabled/disabled by the user for the
  mcmc function, which is necessary for models where it might not be from the
  prior even though nObs == 0.

* Bugfix: The results from the MinimalInformative function were not reproducible
  beforehand. Now a seed parameter can be supplied, which ensures 
  reproducibility.

* Bugfix: Compatibility of help file links with new ggplot2 package version.

Version 0.1.5
--------------------------------------------------------------------------------

* Bugfix: In newer versions of grid the plotting of simulation objects did no 
  longer work. This was fixed.

Version 0.1.2
--------------------------------------------------------------------------------

* Bugfix: The MinimalInformative function previously produced too uninformative
  prior quantiles, which were not fulfilling the requirements in the function's
  documentation. With this bugfix, the correct (as per the Neuenschwander et al
  (2008) publication) prior quantiles are specified and then approximated with
  logistic (log) normal priors.

Version 0.1.1
--------------------------------------------------------------------------------

* Bugfix: Previously, it could happen with NextBestNCRM rule, that higher doses
  lead to decreasing probability of overdosing, only because for some doses
  there was numerically probability 1 of having a DLT. With this bugfix, it was
  clarified in the rules documentation and fixed in the rule method, that the
  right limit of the overdose interval vector will be inclusive.

Version 0.1.0
--------------------------------------------------------------------------------

* Added examine function to generate a table of hypothetical trial courses
  for model-based and rule-based DLT-endpoint designs

* Made results from mcmc() (works with the usual set.seed in earlier user code)
  and simulate() (as previously already promised) reproducible. See help file
  for mcmc for more details. Additional improvements to reduce confusing warning
  messages / notes from mcmc() and higher-level functions.

* Made simulate with parallel=TRUE work on r.roche.com (Linux server),
  using the same parallelization method as for laptops (Windows)

* Passing an empty (zero length) vector as the doselimit parameter of the
  nextBest function is now considered as requesting a dose recommendation
  without a strict dose limit, and a corresponding warning is printed.

* Introduced GeneralModel class, from which then the class Model for single
  agent dose escalation derives. Another branch will be the ComboLogistic model
  for multiple agent combinations (in a future version). Similarly introduced
  GeneralData class, from which the class Data for single agent derives,
  separately from that will be the subclass DataCombo (in a future version).

Version 0.0.23
--------------------------------------------------------------------------------

* Fixed bug in mcmc function which led to error
  "all data elements must have as many rows as the sample size was" and slightly
  changed JAGS way of handling burnin / thinning (which should not have a user
  impact).

* Reduced number of MCMC samples for dual-endpoint example in vignette to be
  able to plot the vignette

Version 0.0.22
--------------------------------------------------------------------------------

* simulate function has been fixed (specification of arguments)

* Dual-endpoint model-based design has been added.

* 3+3 design simulation is now possible, see ?ThreePlusThreeDesign

* Welcome message on attaching crmPack, i.e. when library("crmPack") is
  run

* crmPackUpgrade() function for easy upgrade of crmPack to the latest version

* Rule-based designs now can be specified with the class RuleDesign, while the
  model-based designs stay with the class Design. An even more special class is
  the DualDesign class, for dual-endpoint model-based designs. Corresponding
  classes GeneralSimulations, Simulations and DualSimulations capture the output
  of the trial simulations for rule-based, model-based and dual-endpoint
  designs.

* The class Simulations-summary has been renamed to SimulationsSummary,
  similarly for the classes GeneralSimulationsSummary and
  DualSimulationsSummary.

* All Stopping and CohortSize rules that are based on intervals
  (IncrementsRelative, IncrementsRelativeDLT, CohortSizeRange, CohortSizeDLT)
  now use a different intervals definition. Now the "intervals" slots only contain
  the left bounds of the intervals. Before, the last element needed to be
  infinity. See the vignette for examples.

* StoppingMaxPatients class has been removed, as it was redundant with the class
  StoppingMinPatients. Please just use the StoppingMinPatients class instead.

* Initialization methods have been replaced by dedicated initialization
  functions. Please now use these Class(...) functions instead of new("Class",
  ...) calls to obtain the correct objects. This change is also reflected in the
  vignette.

* The extract function for extracting parameter samples from Samples objects has
  been removed (due to a name conflict with ggmcmc dependency packages). Please
  now use instead the "get" method for Samples objects (see the vignette for an
  example) to obtain data in the ggmcmc format.

* crmPack now needs the package httr (it's now in the "Imports" field). Packages
  Rcpp and RcppArmadillo have been moved from "Depends" to "Suggests" packages.
  Currently we are not using them at all.

* showLegend argument for model fit plotting functions, in order to show the
  legend or not.
