Subject Re: [DISCUSS] How to generate RC's
Date Mon, 13 Jan 2014 15:17:00 GMT
#1 - No strong opinions.
#2 - I want to make the transition for committers from one branch to the
next as painless as possible. In particular, I'm worried that somebody will
not realize they need to switch branched and accidentally push e.g.
1.4.5-SNAPSHOT after we create a 1.4.6-SNAPSHOT branch. I really really
want just a general 1.4 branch to deal with this case. (And similarly
applied to the other lines.)

What do you mean "put down the info... with the git-archive?" Listing the
exact command?

Another thought I had on this - what kind of tags are we using?
Lightweight? Annotated? Signed?

I think 1.4.4 has been the only git release, and I used a lightweight tag
due to ignorance rather than choice.
