[IPython-dev] What do we do about repository formats???

[Fernando Perez]

I've realized I let this linger without action, and we probably should
do something about it while it's (relatively) fresh in our minds.

So, as a concrete proposal, I can update the remote repo say by this
weekend, giving anyone with local changes in any branch time to merge
them.  By Sunday I will start a remote repo upgrade, and we'll all
simply have to run local upgrades before doing any further operations.

Does that sound OK, have I missed anything?

Yes, it's annoying because they more or less forced projects to deal
with the issue to some extent right away, without any clear head
warning.  But it doesn't matter, we can do it and move on.

That's a topic for another day, but I'd be curious about your
experiences.  The more I use git the more I like it and I've only used
hg very lightly, so I'd be interested in this.
