[Numpy-discussion] 1.8 release
Mon Jan 14 05:59:28 CST 2013
I tried to suggest this for our matplotlib development cycle, but it didn't
get the roaring response I was hoping for (even though I was being
conservative by suggesting a 8-9 month release time):
In essence, I think there is a lot of benefit in getting releases out
quicker. The biggest downside, IMHO, is that those who package the binary
releases have to work more frequently on what is not a particularly
For those who are worried about the quality of releases being diminished by
releasing more frequently, an LTS approach could also work.
Good luck on getting these frequent releases going, IMHO there is a lot to
be said for having users on the latest and greatest, rather than have users
on old versions & still finding bug which were introduced 24 months ago and
fixed 12 months ago on master...
