Dates correspond (roughly) to SSC Archive releases.

26oct2019 (version 1.2.6)
- the -nokeep- graph option had no effect if the graph format was SVG; this is
- in Stata 16, SVGs embedded in the HTML file did not always display correctly
  because -webdoc append- (which is used to copy the SVG to the HTML file) 
  was breaking very long lines (> 32,768 characters) due to an internal limit 
  of Mata's -fget()- function; this is fixed
- -webdoc graph- now passes options -weight()- and -height()- through to 
  -graph export- in all cases; in earlier versions, -weight()- and -height()-
  were only taken into account for PNG and TIFF
- the default width of 500 pixels is now also applied to GIF and JPEG, not only
  to PNG and TIFF (this is currently only relevant for Sata 16 on Mac)

- sthlp() option of -webdoc stlog- now has a -noid- suboption to ignore the
