FYI, (this one gave me alot of headache)

Undocumented change:
(in object tag)

Code:
[PARAM NAME=movie VALUE="test.swf?txt=BUbub"]
[PARAM NAME=quality VALUE=high]
[PARAM NAME=FlashVars VALUE=txt=BABA]
(replace brackets with less than / greater than)

6.0.29.0 will set txt to BUbub
6.0.47.0 will set txt to BABA
