Melchior FRANZ:

Turn the material animation's <transparency> property into a group, with
members <alpha-prop>/<alpha>, <offset-prop>/<offset>, <factor-prop>/<factor>,
<min>, and <max>. The "material" animation can now fully replace "blend" and
"alpha-test" (--> <threshold>) animations, with enhanced possibilities:
The "material" animation can be used for one or more explicit objects (like
"blend"), but also for all objects that share one material (<global>), which
avoids problems with objects being forced together into one tree. Also, an
object doesn't have to be semitransparent or textured with a semitransparent
texture to make blending work. Unlike the "blend" animation, the "material"
animation also makes fully opaque and untextured objects transparent. (This
fixes the bo105's formerly semi-transparent rotor.)

Erik:
The blend animation and alpha-test animation are depreciated as of now.
