1.7-1 (2013-02-24)
  * Fixed logicals bug (Req #1911)
  * Changed implementation of centering of tables. Instead of
    inserting a centered environment, now a \centering command is
    inserted. (Req #2104)
  * Allow for margin tables as possible with document class 
    tufte-handout. An example of usage is found in the vignette 
	produced by margintable.Rnw which is in inst/doc. (Req #2168)
  * Added "timestamp" argument to print.xtable().  Set it to NULL
    if no timestamp is desired. (Req #2246)
  * Added "comment" argument to print.xtable().  Set it to FALSE
    to exclude the version and timestamp comment. (Req #2246)
  * Added "caption.width" argument.  If not NULL then the caption
    is placed in a "parbox" of the specified width. (Req #2247)
  * Remove the check on whether the "floating.environment" is
    in a list of known floating environments. Users want to use
	floating environments from multiple options LaTeX 
	packages (Req #2488, #2578)
	
1.7-0 (2012-02-10)
  * Added some vectorization code to improve performance.
  * Let "caption" be length 2, in which case the second value is 
    the short caption used when creating a list of tables.
  * Added "toLatex" method.
  * Included "print.xtable" in the exported methods in the NAMESPACE file.
  * Added "print.results" argument to "print" that can be used to
    suppress the printing.
  * Added "format.args" argument to "print" that can be used to
    pass additional arguments such as "big.marks" to "formatC()".
  * Added "rotate.colnames" and "rotate.rownames" arguments to
    "print.xtable".  
  * Added "booktabs" argument to use the "\toprule", "\midrule", and  
    "\bottomrule" tags from the Latex "booktabs" package rather than
	using "\hline" for all horizontal lines.
  * Added "scalebox" argument to include a "\scalebox" clause around
    the tabular environment with the specified value used as the
    scaling factor.	
  * Added "width" argument to allow specification of the width
    value in tabular environments such as "tabularx".
  * Added "X" as an allowed alignment value in the "align()"
    replacement function.  
  * Changed the "print.xtable()" arguments to use "getOption()"
    to check the options for a default value.  This was suggested
	since "print.xtable()" has a lot of arguments that the user
	will typically leave unchanged between tables.
  * Added an "is.null()" check on the "table.placement" argument.
  * Added examples using the new arguments to the vignette.
	
1.6-0 (2011-10-07)
  * Allow "table*" as a value for "floating.environment" in print.xtable().
  * Fix bug under which multiple logical columns were formatted incorrectly.
  * Stop with an error if "xtable.table" is used on a table with more than
    two dimensions.
  * Add some newlines to "Rd" file to prevent lines from extending off the
    page in the PDF version of the help files.
  * Changed the maintainer to "Charles Roosen".
  * Created an "xtable" project on R-Forge.

1.5-6 (2009-10-30)
  * Support caption at the top in the LaTeX longtable.
  * Use options()$OutDec for decimal mark.

1.5-5 (2009-03-24)
  * Added html.table.attributes to set the attributed of the <TABLE> tag for HTML tables.
  * Accommodated logicals by converting to characters.
  * Add an extra space at end of each line for LaTeX tables.
  * Fixed typographical error in documentation.
