			==== gridplot title ====
			You can add a title to a gridplot now.
			<pre>
			open bikesharing

			gnuplot temp --time-series
			gnuplot casual --time-series
			end gpbuild

			gridplot bikers --title="Cool bikers" --output=display

			==== Dynamic scaling of fonts in many gretl windows ====

			You can enlarge or shrink the font size very much like in a web browser, for example using ctrl_+ or ctrl_- keys.

			==== Gamma distribution in distribution plotting tools ====

			he distribution plotting tool (under the Tools menu) now also supports the Gamma distribution.

			==== Panel dataset subsampling ====

			If you're subsampling a panel dataset with the graphical dialogs, telling gretl to maintain the panel structure is now easier.
