I also think that, to promote evolution of the PureData source code base, when Miller's 0.39 gets published, diffs between Miller's 0.38 and 0.39 should be merged to devel_0_38, and not the other way around. This is especially important if there is more work being done on the non-Miller side than on the Miller side.
well, i don't know, what miller is planning for 0.39, but i'm not willing to merge the devel_0_38 branches to 0.39 ... i did it once from 0.37 to 0.38 and it was a pain.
- there are too many changes in devel_0_38 at the moment ... and still increasing - some of the changes are too heavy to be easily merged, the simd stuff is all over the pd code ... dsp objects, dsp tree, audio i/o - it doesn't seem that miller is incorporating any of the devel_0_38 features to 0.39
merging miller's changes to devel won't be fun, either, since it will most likely break some features ... but it's not as bad as the other way around ...
cheers ... tim
