-----------------------------------------
bq. It's about Apache too.
Not true. You mean It's about Apache Hadoop HDFS too.
bq. This whole "stable" vs "beta" vs "alpha" thing is a new concept, with
nothing written about it in our bylaws.
I think we should write about this in our bylaws. But, Alpha release is a
widely used term in software engineering. People do not usually deploy them in
production or if they do, they generally understand the associated risk. Here
are some links:

bq. Breaking compatibility screws users, regardless of distro. If it's
required, let's do it.
Well just superficial review of our protobuf stuff has shown many bugs that
require incompatible changes. I continue to do the review that I was planning
to do before declaring GA. I am sure to find more.
Meanwhile, I will escalate this at an appropriate time.
