Many of the new entries this week deal with Pakistan. President Pervez Musharraf expressed his public support for the Taliban in May 2000, and the ISI then assisted an autumn offensive by the Taliban. After taking office, the Bush administration was slow to develop a new policy on Afghanistan and Pakistan, and only gave Pakistan vague warnings about its links with Osama bin Laden three months before 9/11. After the attacks, Richard Armitage made his disputed "stone age" comment, but the ISI secretly advised the Taliban to resist the US-led invasion.

One of the main additions to the 9/11 Timeline this week is a category dealing exclusively with the report drafted by the CIA's inspector general about some aspects of the agency's poor performance before 9/11. It deals with the report's origins, its redrafting at the insistence of the CIA's management, and the final release of a redacted executive summary. You can read a summary of the whole chapter here.
