Changes in Version 1.9-4

  o Several functions now use find.package() rather .find.package()
    internally (as the latter will be deprecated soon).


Changes in Version 1.9-3

  o Enforced .tex suffix in LaTeX files used internally by exams2pdf().
    The lack of .tex suffixes led to errors on certain Windows systems.


Changes in Version 1.9-2

  o New demo exercises:
    - confint2.Rnw shows how a confidence interval can be embedded into a
      "cloze" question (for all version 2 interfaces).
    - dist.Rnw is a very short and simple example that is intelligible
      across a wide range of disciplines (not for statistics audiences only).
    - dist2.Rnw is an extension of dist.Rnw that is written as a "cloze".

  o Questions in exams2moodle() were forced to be <pre>-formatted,
    now embedded in normal HTML (without <pre> tags).
  

Changes in Version 1.9-1

  o Supplementary files had not been correctly inferred on Solaris
    systems. This has been fixed now so that the package behaves the
    same across different platforms.
    
  o The code underlying the old "exams" vignette now avoids opening PDF
    viewers.


Changes in Version 1.9-0

  o Major revision of the "exams" package, adding flexible support for
    generation of exams in different formats including PDF, HTML,
    Moodle XML, and QTI 1.2 (for OLAT). This new version of the exams
    package (called "version 2") is described in a new vignette:
    vignette("exams2", package = "exams")


Changes in Version 1.0-4

  o Added an {answerlist} environment in the LaTeX templates (inst/tex)
    so that each \item in the {answerlist} is automatically labeled
    with (a), (b), (c), ...

  o Replaced the old {itemize} environments with {answerlist} in
    anova.Rnw, boxplots.Rnw, relfreq.Rnw, scatterplot.Rnw, ttest.Rnw.
    (The resulting PDFs do not change.)


Changes in Version 1.0-3

  o Small improvements in solution string formatting.


Changes in Version 1.0-2

  o The argument "nsamp" was added to exams() in order to allow
    sampling more than one exercise from each element of the
    argument "file".


Changes in Version 1.0-1
  
  o The man page of exams was modified to use suitable markup commands.

  o The questions in the ANOVA example were slightly changed to more
    explicitly indicate which hypothesis is tested. A typo in the
    vignette was fixed.


Changes in Version 1.0-0

  o New version accompanying publication in the Journal of
    Statistical Software. See vignette("exams", package = "exams")
    for more details.
    
  o New CITATION file pointing to the JSS paper, see
    citation("exams").


Changes in Version 0.9-5

  o The possible types of questions were extended to allow also text
    results. The new type is specified by "string".

  o To specify the allowed tolerance for numeric solutions now
    different tolerances can be supplied for falling below or
    exceeding the true value via \extol{lower}{upper}.

  o The "discussion" section in the vignette was extended to include
    several remarks and pointers on strategies for exercise
    generation.


Changes in Version 0.9-0

  o First CRAN release version.
  
  o New vignette "exams" that explains how to use the package.
  
  o New set of exercises for illustation in examples and vignette.
  

Changes in Version 0.2-0

  o First stable version for internal use at WU Wien.
