I don't see any change in the file format except the following:
In GIMP 1.3, gradients have an extension ".ggr" and don't encode
thair name in the filename anymore but inside the .ggr file:
GIMP Gradient
Name: Abstract 1
6
0.000000 0.286311 0.572621 0.269543 0.259267 1.000000 1.000000 0.215635 0.407414 0.984953 1.000000 0 0

Which is still so ugly that i think we should never allow the new
format to become used, but port it to a GimpConfig style format:
<proposal>
# GIMP Gradient file
(GimpGradient "Abstract 1"
(segment 0.000000 0.286311 0.572621
(left-color (gimp-rgba 0.269543 0.259267 1.000000 1.000000))
(right-color (gimp-rgba 0.215635 0.407414 0.984953 1.000000))
(blending-function linear)
(coloring-type rgb))
(segment ...)
...
(segment ...))
</proposal>
Of course, GIMP would continue to read the old files.
ciao,
