I think this is a huge problem if we're going to introduce changes like this *after* the regression tests have already been run (or are nearly done). Doesn't this totally wreck the QA cycle to introduce widespread changes like this *after* regression tests have been running for weeks? I really cannot support this unless the QA team is comfortable with having their testing invalidated and is willing/able to rerun all of their regression tests. Also, it is not clear to me what the benefit is of merging stlport into the trunk at the last minute? > - Create a AOO 4.0 branch 1 week later, June 10th, where we hopefully > have integrated already returned translations. > > - Translation deadline will be set to June 14th to have some time for > the integration and further testing.

Maybe you can more fully describe the test impact. My impression was the impact would be widespread and could introduce bugs into any part of the product. Is that true? If so, how can we avoid doing a complete regression test pass? As you know that takes several weeks, and that also puts us into vacation season.
