As Florent often puts it: before switching, we were about to run hard
into a wall. Now, we don't see a wall in front of us any more, but we
are also going much faster :-)
Seriously speaking: it's not as smooth as I would like it to be. We
are making a much better work at creating and developping new patches
(containing new features, bug fixes and refactorization) than at
finalizing and reviewing them (and I take a good share of the blame on
that). By consequence, the patches tend to accumulate in our queue
beyond really reasonable. In particular, there are a bunch of patches
about categories, morphisms, tutorials that overlap with the amazing
job that Simon is currently doing, with increasing risks of conflicts.
That being said, we still manage to get an average of 25 patches in
Sage in every release, which is not so bad. Also, the more time
passes, the more the patches are on the periphery rather than on the
core features. Due to that, they tend to overlap and conflict less
with each other, and with Sage ongoing development. So it is not as
vital to get them merged swiftly.
Cheers,
Nicolas
