Build 3.5.0.42 of xlsgen improves a recent build (3.5.0.35) by adding more trendline options to the built-in chart rendering of trendlines. This build comes with the support of moving average trendline type, of any period, as well as the computation and showing of the equation of the trendline, as well as the support of the formatting properties of this equation. So if you are into trendlines, this should be a welcome update.
