Notes:

1) Firefox3.5 was the first time we did a major update at the same time as the release. This caused additional RelEng and QA work and is included in the times above.
2) Our blow-by-blow scribbles are public, so the curious can read about it, warts and all, here. Those Build Notes also link to our tracking bug#499687.
3)The extra long wait before the end of the release, was to wait for feedback of possible issues from beta users of 3.5rc3, as well as technical and media preparations specific to this large scale release event.
take care
John.
