`Since` is missing in docs
I was looking at https://gnome.pages.gitlab.gnome.org/gtk/Pango/method.Layout.set_line_spacing.html and found the API was only from Pango 1.44
, but there is no information about that on the doc page. I would like to have them shown in the docs. I could see Pango specifies them https://gitlab.gnome.org/GNOME/pango/-/blob/master/pango/pango-layout.c#L638 and is shown in old docs https://developer.gnome.org/pango/1.46/pango-Layout-Objects.html#pango-layout-set-line-spacing also.
Thanks.
