\section{Changes in rkwarddev version 0.08-2 (2017-07-28)}{
  \subsection{fixed}{
    \itemize{
      \item \code{rk.uniqueIDs()} was using lists internally in some cases which caused an
        unneccessary warning
      \item \code{rk.XML.formula()} was missing the label attribute (also missing in the
        documentation)
      \item \code{rk.JS.scan()} omitted <formula> nodes
      \item re-implemented the dropping of variables if they're globally defined in
        \code{rk.JS.doc()}
      \item private function \code{p2s.checkModifiers()} (called by \code{plugin2script()}) didn't
        detect *.not modifiers correctly
      \item \code{plugin2script()} does now output numeric values when mandatory; internally
        this is defined in the FONA list
      \item \code{rk.XML.about()} now prints dates correctly
      \item \code{rk.XML.vars()} now knows type \code{"numeric"} instead of \code{"number"}
      \item fixed tests/generate_test_standards.R (replacing \code{"number"} with \code{"numeric"})
      \item \code{rk.JS.header()} doesn't fail any longer if \code{".add"} vectors have no names
    }
  }
  \subsection{changed}{
    \itemize{
      \item internal function \code{get.IDs()} now uses new internal function
        \code{filter.relevant.tags()}
      \item function \code{rk.JS.scan()} now has a new mode switch and supports scanning for
        <preview /> nodes
      \item \code{rk.JS.scan()} can now also check if a variable is actually being used in
        the script body (if given via the new script argument), and if not omit it
        from its result; this is the new default, but can be turned off by setting
        the new argument unused.vars=TRUE in \code{rk.plugin.component()} and
        \code{rk.plugin.skeleton()}
      \item handling of previews was changed; using \code{"doPrintout"} is deprecated now,
        but still works. most scripts should still do without changes, allthough
        the JS code looks different now
      \item improved output of \code{rk.JS.doc()}
      \item improved the handling of <frame> nodes in JS code: previously \code{id()} just
        returned the camelCode id of frames, you had to manually define an object
        outside \code{rk.paste.JS()} via rk.JS.vars(<frame object>, modifiers=\code{"checked"}).
        the default is now to add the checked modifier, since using frames in JS
        is most likely useless otherwise. i.e., you now need to manually call via
        rk.JS.vars(<frame object>) with no modifiers if you happen to need the
        frame's ID for whatever reason
      \item adjusted \code{plugin2script()} to the new \code{rk.XML.preview()} parameters (see
        \code{"added"})
      \item \code{rk.XML.embed()} now also accepts objects of class rk.plug.comp as
        components
      \item \code{rk.plotOptions()} gained new argument namespace to work well with the
        changed approach of \code{rk.XML.embed()}
      \item \code{rk.XML.connect()} now allows objects of class rk.plug.comp to be used as
        clients and <external> nodes to be used as the \code{"set"} modifier for that
        client, and can therefore be used to connect properties from embedded plugins
      \item objects of class rk.JS.var now have a new slot \code{"methods"} to append method
        calls
      \item moved internal \code{js.try.scan()} function from body of \code{rk.plugin.component()}
        to rk-internal.R
      \item \code{rk.XML.about()} finally no longer supports \code{"dependency"}, \code{"package"} or
        \code{"pluginmap"}; these arguments were deprecated for years now
      \item adjusted test standards
    }
  }
  \subsection{added}{
    \itemize{
      \item new parameters \code{"mode"}, \code{"placement"}, \code{"active"} and \code{"id.name"} in
        \code{rk.XML.preview()}
      \item new parameter \code{"preview"} in \code{rk.JS.doc()} to force adding a \code{preview()}
        function
      \item \code{rk.plugin.component()} and \code{rk.plugin.skeleton()} now support \code{"preview"} in
        both the \code{"js"} option and the \code{"scan"} option
      \item new options \code{"preview"} and \code{"level"} in \code{rk.JS.saveobj()}
      \item \code{id()} gained the new attribute \code{"guess.modifier"} to toggle the new default
        for <frame> nodes in JS (see above)
      \item new parameter \code{"namespace"} in \code{rk.XML.embed()} to result in
        "namespace::component", takes character strings, <about> nodes and pluginmap XML trees and
        is not yet covered by \code{plugin2script()}
      \item new function \code{rk.JS.method()} to generate JS method calls
      \item \code{plugin2script()} now also scans *.rkh and *.pluginmap files
      \item \code{rk.JS.header()} now accepts rk.JS.ite objects as the second value of \code{"add"}
        entries and prints them in a condensed statement
    }
  }
}
\section{Changes in rkwarddev version 0.08-1 (2015-12-17)}{
  \subsection{fixed}{
    \itemize{
      \item attribute \code{"max_precision"} in <spinbox> was misspelled
      \item \code{rk.XML.connect()} still handled modifiers for \code{"governor"} wrong if it
        wasn't a XiMpLe node
      \item also fixed how \code{rk.XML.convert()} and \code{rk.XML.switch()} were handling
        modifier checking
      \item \code{rk.XML.dependencies()} didn't know about min/max versions of pluginmaps
        (fixed in \code{rk.XML.about()} as well)
      \item some fixes to the skeleton GUI and demo script
      \item prevent internal function \code{indent()} from losing it over negative values
      \item indentation of \code{rk.paste.JS.graph()} was incorrect
      \item pasting comments via \code{rk.paste.JS()} gained an extra space for subsequent
        lines
      \item the \code{"i18n"} attribute in lists e.g. for \code{rk.XML.radio()} didn't really work
      \item improved indetation for rk.JS.oset objects
      \item \code{rk.XML.varslot()} and \code{rk.XML.valueslot()} didn't correctly add sources if
        they were character strings (which is valid)
      \item \code{R.comment()} didn't correctly paste indentation levels > 2
    }
  }
  \subsection{added}{
    \itemize{
      \item new methods \code{plugin2script()} to try to translate raw plugin XML into
        working rkwarddev script calls
      \item new option \code{"ignore"} enables \code{rk.uniqueIDs()} to not check nodes for
        duplicates (e.g., <copy>)
      \item new wrapper function \code{js()} for \code{id()} makes it possible to use several
        operators without quoting, preserve \code{"if"} conditions and \code{"for"} loops, which all
        will be translated to JavaScript equivalents without the need for quoting.
        however, the \code{"for"} loop code is not publicly documented and remains a
        proof of concept kind of thing for now
      \item new option \code{".objects"} in \code{id()} and \code{".ite"} in \code{rk.JS.options()} to provide
        objects as a list
      \item new option \code{"rk.JS.vars"} to make JS variables match the name of the
        original R object
      \item new function \code{idq()} to print quoted IDs of XML nodes for use in JavaScript
        sections
      \item new function \code{modifiers()} to make checking for valid mdifiers of a given
        node easier
      \item new functions \code{rk.get.indent()} and \code{rk.set.indent()} to globally set
        indentation string
      \item new functions \code{rk.get.empty.e()} and \code{rk.set.empty.e()} to globally define
        the handling of empty \code{"else"} clauses in JavaScript
      \item in \code{rk.JS.header()}, the second value provided by \code{"add"} can now be named
        \code{"noquote"} to have it nested in the JS \code{noquote()} function
      \item new wrapper function \code{rk.updatePluginMessages()} for
        update_plugin_messages.py, the package now comes with its own copy of this core i18n script
      \item the generator info gained support for hinting at the very rkwarddev
        script file that was used to generate a particular plugin file
      \item new function \code{rk.local()} to be used as an alternative to \code{local()} with a
        predefined local environment to solve scope issues with \code{js()}
    }
  }
  \subsection{changed}{
    \itemize{
      \item improved error handling in \code{rk.JS.header()}, error messages are more
        informative now
      \item \code{rk.uniqueIDs()} now checks \code{"dialog"} and \code{"wizard"} sections separately
      \item updated the vignette with information on \code{js()}, \code{plugin2script()}, and how
        to add help pages
      \item internal function \code{modif.validity()} now calls \code{modifiers()} to give more
        useful feedback
      \item all functions offering \code{"intent.by"} as an option now fetch the default
        value by calling \code{rk.get.indent()}
      \item all functions offering \code{"empty.e"} as an option now fetch the default value
        by calling \code{rk.get.empty.e()}
      \item removed trailing newline in \code{rk.JS.header()} output
      \item updated test standards
    }
  }

\section{Changes in rkwarddev version 0.07-3 (2015-06-29)}{
  \subsection{fixed}{
    \itemize{
      \item \code{rk.JS.header()} now produces usable level options
    }
  }
  \subsection{added}{
    \itemize{
      \item new slot \code{"opt.sep"} in classes rk.JS.arr and rk.JS.opt, as well as new
        option \code{"opt.sep"} in \code{rk.paste.JS()}, \code{rk.JS.array()} and \code{rk.JS.options()}, to
        manipulate the character string separating the previous options from the ones
        defined by these objects

\section{Changes in rkwarddev version 0.07-2 (2015-03-14)}{
  \subsection{fixed}{
    \itemize{
      \item replaced the outdated links to sourceforge with our new KDE URL
    }
  }
}
\section{Changes in rkwarddev version 0.07-1 (2015-03-13)}{
  \subsection{fixed}{
    \itemize{
      \item \code{rk.XML.optionset()} does now allow to re-use objects defined in the same
        function call (i.e., refer to optioncolumns in the logic section)
      \item removed arguments \code{"help"} and \code{"component"} from \code{rk.XML.optionscolumn()}
        again, as these are already being documented via the objects they connect to.
      \item \code{rk.build.plugin()} was still only using the "--no-vignettes" option from R
        < 3
      \item \code{rk.XML.pluginmap()} malformed label argument names if they referred to
        standrad maneu entries
      \item \code{rk.plugin.skeleton()} still allowed invalid IDs, fixed the regexp
      \item \code{rk.XML.snippets()} now also accepts <include> as child node
      \item \code{rk.XML.tabbook()} returns <insert> nodes as-is, not nested in <tab></tab>
      \item \code{rk.JS.scan()} now sets \code{"state"} as default modifier for checkboxes if
        guess.getter is TRUE
      \item \code{rk.XML.connect()} handled modifiers too strict if \code{"client"} was a string,
        and too liberal when \code{"governor"} was
      \item \code{join()} referenced a wrong object name if \code{"var"} was of class rk.JS.arr
      \item \code{rk.XML.about()} had a malformed error message
      \item \code{rk.plugin.component()} called \code{XMLAttrs()} with too many arguments
      \item \code{rk.XML.values()} and \code{rk.XML.vars()} do now handle all combinations of
        \code{"horiz"} and \code{"add.nodes"} properly
      \item fixed wrong link to \code{rk.plugin.skeleton()} in documentation of
        \code{rk.XML.pluginmap()}
    }
  }
  \subsection{added}{
    \itemize{
      \item all \code{"help"} values can now be a list of character strings or XiMpLe nodes,
        to have more control over the markup
      \item added \code{"property"} and \code{"duplicates"} arguments to \code{rk.XML.valueslot()} and
        \code{rk.XML.varslot()}.
      \item \code{rk.XML.pluginmap()} now adds a \code{"po_id"} attribute to pluginmaps, necessary
        for i18n
      \item new attribute \code{"require.defaults"} in \code{rk.XML.pluginmap()} to add
        rkward::menu and rkward::embedded as requirements
      \item new attribute \code{"i18n"} added to several XML functions; it takes a list with
        the named arguments \code{"comment"} or \code{"context"} to either produce an i18n
        comment node or an \code{"i18n_context"} attribute
      \item new function \code{rk.i18n.comment()} to give context for translators
      \item new function \code{rk.JS.header()} to easily generate JavaScript header code fit
        for i18n
      \item \code{rk.JS.doc()}, \code{rk.plugin.skeleton()} and \code{rk.plugin.component()} now use
        \code{rk.JS.header()} instead of \code{rk.header()}, and also accept its \code{"header.add"}
        attribute
      \item new function \code{R.comment()} to generate JavaScript "\code{comment()}" calls
      \item first unit tests using the testthat package
      \item added documentation to the used S4 classes
      \item enhanced \code{rk.XML.values()} to also accept \code{"options"} and \code{"duplicates"}, and
        \code{rk.XML.vars()} to also accept \code{"duplicates"}
      \item new argument \code{"var"} in \code{rk.paste.JS()} to define whether the JS keyword
        \code{"var"} should be used or omitted for rk.JS.var objects
      \item \code{rk.XML.matrix()} now also accepts the arguments \code{"min_rows"} and
        \code{"min_columns"}
      \item <dropdown>, <radio> and <select> have gained \code{"string.quoted"} as a valid
        property/modifier
      \item new function \code{rk.XML.i18n()} to define translatable labels in logic sections
      \item new function \code{rk.rkh.label()} for extracting labels from plugin elements
    }
  }
  \subsection{changed}{
    \itemize{
      \item function \code{i18n()} was changed to be used in JavaScript generation only;
        this breaks code using the function introduced with 0.06-4, but that was to
        be shortlived from the start... the i18n features of 0.06-4 will be
        completely replaced with some proper methods now
      \item comment nodes (<!-- foo -->) are now globally allowed as child nodes in
        XML; important for i18n comments
      \item modifier checks now point to rkwarddev:::all.valid.modifiers directly in
        case of errors
      \item internally, moved the definitions of valid child nodes and modifiers as
        well as default getter functions and modifiers to separate files, so
        they're more obvious to find and check
      \item \code{rk.XML.input()} now checks wheter \code{"size"} is exactly one of \code{"small"},
        \code{"medium"} or \code{"large"}
      \item \code{rk.JS.doc()} now uses a more robust method to set global variables, namely
        by defining an additional function \code{setGlobalVars()} and calling that
        inside \code{preprocess()}
      \item due to changes needed for i18n and \code{rk.JS.header()} to work, check your
        \code{"result.header"} values, there might be quote issues. for the most part,
        remove quotes you added for rkwarddev >= 0.05-0
      \item updated the generation of author and maintainer fileds in DESCRIPTIONs
        made by \code{rk.plugin.skeleton()}, borrowing \code{get.authors()} from roxyPackage
      \item \code{rk.plugin.component()} will now also move <dependencies> from <about> to a
        top level child node of plugin XML code, with a warning
      \item \code{rk.plugin.skeleton()} has a new logical switch called \code{"internal"}, to set
        some defaults for plugins to be distributed with RKWard itself
      \item the \code{"pluginmap"} argument of \code{rk.plugin.skeleton()} now also accepts
        \code{"namespace"}
    }
  }
  \subsection{removed}{
    \itemize{
      \item the functions \code{rk.set.language()} rk.\code{get.language()} were no longer useful
        and therefore removed
      \item also removed the option \code{"lang"} from \code{rk.rkh.doc()}, \code{rk.XML.plugin()},
        \code{rk.XML.pluginmap()} and \code{rk.plugin.skeleton()}
    }
  }
}
\section{Changes in rkwarddev version 0.06-5 (2014-10-19)}{
  \subsection{fixed}{
    \itemize{
      \item the \code{"show"} feature in \code{rk.plugin.skeleton()} was broken due to changes in
        the namespace defaults
      \item scanning plugin XML code for JS and help related content didn't work as
        expected in \code{rk.plugin.component()}
      \item \code{rk.rkh.scan()} now also recognises <optioncolumn> and <matrix> nodes
      \item a logical bug prevented \code{rk.plugin.component()} to run with default values
        for XML
      \item internal function \code{paste.JS.options()}, used by \code{rk.JS.options()}, was only
        working correctly for the \code{"then"} part if \code{ite()} statements in arrays; now
        also produces usable code for an \code{"else"} part, if available
    }
  }
  \subsection{added}{
    \itemize{
      \item new functions \code{rk.XML.valueselector()},  \code{rk.XML.valueslot()} and the
        combining \code{rk.XML.values()} to define <valueselector> and <valueslot> nodes,
        similar to \code{rk.XML.varselector()},  \code{rk.XML.varslot()} and \code{rk.XML.vars()}
      \item new function \code{rk.XML.select()} to define <select> nodes
      \item new functions \code{rk.set.rkh.prompter()} and \code{rk.get.rkh.prompter()} to make it
        easier to generate help files (later...)
      \item \code{rk.rkh.scan()} (and automatically \code{rk.plugin.skeleton()} and
        \code{rk.plugin.component()}) are now capable of fetching text set with \code{rk.set.rkh.prompter()}
        and use it to generate help files
      \item all functions scanned by \code{rk.rkh.scan()} for setting nodes in .rkh files
        have gained two additional arguments, \code{"help"} and \code{"component"}, to register
        the text to be used via \code{rk.set.rkh.prompter()}
      \item new function \code{rk.XML.option()} to allow setting and accessing IDs for
        single options as well
      \item new function \code{rk.JS.optionset()} and object class \code{"rk.JS.oset"} to generate
        for loops over <optionset> columns
    }
  }
  \subsection{changed}{
    \itemize{
      \item updated the plugin skeleton example script; e.g., it now uses the new
        .rkh file generating features
      \item \code{rk.XML.radio()} and \code{rk.XML.dropdown()} now also accept objects made with
        \code{rk.XML.option()} in their respective list of options
      \item renamed all class definition files due to include problems with
        \code{roxygenize()}
      \item allow non-maintainers to omit email addresses in <about> nodes
    }
  }
}
\section{Changes in rkwarddev version 0.06-4 (2014-09-14)}{
  \subsection{added}{
    \itemize{
      \item new functions \code{rk.set.language()}, \code{rk.get.language()} and \code{i18n()} to
        facilitate static internationalisation of plugins; makes use of a new internal
        environment .rkdev.env
      \item new parameter \code{"lang"} in functions \code{rk.rkh.doc()}, \code{rk.XML.plugin()},
        \code{rk.XML.pluginmap()} and \code{rk.plugin.skeleton()} for internationalisation. if used, the
        attributes \code{"lang"} and "xml:lang" will be set in the <document> root of
        the generated files, respectively
      \item new parameter \code{"localized"} in \code{rk.XML.require()} for internationalisation
      \item the document id in \code{rk.XML.pluginmap()} can now be set manually
    }
  }
  \subsection{fixed}{
    \itemize{
      \item abbreviation of labels now limits valid characters to [0-9A-Za-z]
      \item in \code{rk.XML.pluginmap()}, \code{"components"} and \code{"hierarchy"} may be set to NULL if
        \code{"require"} is used accordingly

  }
}
\section{Changes in rkwarddev version 0.06-3 (2013-12-21)}{
  \subsection{fixed}{
    \itemize{
      \item fixed outdated example code for \code{rk.plugin.component()}
    }
  }
  \subsection{added}{
    \itemize{
      \item new function \code{rk.uniqueIDs()} checks for duplicate IDs
      \item \code{rk.JS.array()} can now be told to quote values
    }

  \subsection{changed}{
    \itemize{
      \item \code{rk.plugin.component()} and \code{rk.rkh.doc()} do now interpret the \code{"hints"}
        argument to prevent the generation of optional XML nodes.
      \item \code{rk.plugin.component()} now automatically calls \code{rk.uniqueIDs()} and stops if
        IDs are not unique
    }
  }
}
\section{Changes in rkwarddev version 0.06-2 (2013-04-04)}{
  \subsection{changed}{
    \itemize{
      \item the structure of <about> nodes will change in RKWard 0.6.1,
        <dependencies> will become a direct child of <document> or <component>, which explains
        several changes in this release. this is not really critical, because this
        information wasn't evaluated by RKWard until now anyway
      \item for consistency, from now on <component> is never an empty node
      \item \code{rk.XML.pluginmap()}, \code{rk.XML.plugin()} and \code{rk.plugin.skeleton()} will now
        move <dependencies> from <about> to a top level child node of plugin maps,
        with a warning
      \item from \code{rk.plugin.component()} and \code{rk.XML.plugin()}, the \code{"pluginmap"} argument
        was replaced by the more general \code{"include"}, which can now also process a
        vector of file names
      \item the object class rk.JS.var gained a new slot \code{"getter"} to set a default JS
        function to query variable values. it defaults to \code{"getValue"} to ensure
        compatibility with earlier releases. consequently, \code{rk.JS.vars()} and
        \code{rk.paste.JS()} have a new  \code{"getter"} argument to set or overwrite this value.
        another new argument, \code{"guess.getter"}, can be used to turn on automatic guessing
        which getter function might be most appropriate. this was also added to
        \code{rk.plugin.component()} and \code{rk.plugin.skeleton()}.
      \item updated the skeleton_dialog.R demo file and recreated the plugin code
      \item JavaScript functions like \code{rk.JS.scan()} and \code{id()} learned how to treat
        <optionset>, <optioncolumn> and <matrix>
      \item internally paste(..., sep=\code{""}) was replaced with paste0(...), in a way
        that ensures compatibility with R < 2.15
    }
  }
  \subsection{added}{
