Release version 1.0?

[eschnett]

Recently, version 0.19 was released. Since the major version number is 0, Julia's package manager flags this as incompatible with 0.18, as if this was a major release. I don't think that's a correct description: This was a backward compatible change that introduced a new feature, i.e. truly a minor release.

Should we release MPI 1.0? The MPI standard is stable, the APIs provided here are stable, and adding new functionality will easily remain possible.

I deprecated MPI.Init_thread, so it wasn't quite backward compatible.

I guess the question is if there are any more breaking changes we should make in the near future? The only one I had in mind was #479, but i'd appreciate some input on that before I do anything more.

Oh the other thing is whether Put and Get should have ! suffixes?

[eschnett]

I guess Put shouldn't, but Get should, since it'll modify its argument?

[simonbyrne]

Put modifies an argument on another process though.

[eschnett]

Julia uses put! to put values into a channel. I concede.

It's purely a matter of personal preference, but I'd give the current version (which just introduced another breaking change) some time to mature for a while. If there are no breaking changes in the next 1-2 months, then I see no reason not to bump to v1.

I've created a milestone and added the issues/PRs I thought should be included. If there are any other API breaks you would like to see, either chime in here or open an issue.
