Menus have been reorganized. A new Colors-menu appears. It groups
together all scripts that work on colors, for example tools that
adjust hue, saturation, lightness..., filters...etc. Filters-menu
and Script-Fu-menu are merged in one Filters-menu and it is
organized according to new categories. Image-dependent Plug-ins and
Script-Fus are now disseminated in the image-menus. For example,
Color to Alpha filter is in Colors-menu. At the beginning, it's
disconcerting, but you finish to get used to this because it's more
logical.
The figure below show where you can find them in the image-menu.
