Personally, I think that they do have the same net effect, and just renaming 1.0.0 to 1.0 seems like an easier option. I would have started off the process by just creating a 1.0 branch in the first place, so I guess it's not surprising that I'd go with just renaming. -Patrick On 8/24/07, Marc Prud'hommeaux <[EMAIL PROTECTED]> wrote: > > > This is the first time that you have mentioned merging the 1.0.0 > > branch contents anywhere other than trunk.
