Interesting.
Security updates —when downloaded in
full —are cumulative. That is, Security Update - 2010-003 will contain everything that came before it (e.g., Security Update - 2010-001 and Security Update - 2010-002). The small size of your delta there, as well as the shortness of
this listing (compared to the
previous one), seem to indicate that most of the Pwn2Own stuff got covered by the March 29th update (as well as QuickTime 7.6.6), and yesterday's release was just a minor follow up. Well, "minor" in terms of what was
new since last time. ..
