TLF branch 2.1 has been posted on the source forge http://sourceforge.net/projects/tlf.adobe/files/2.1/.
In Branch 2.1, four high servility bugs are fixed,
- Fix unreported crash that happens when composeToContainer is followed by updateToContainer.
- Fix a crash using floats, Also fixed a bug where an inline graphic was stopped, but not removed from the display list.
- Fix when lineBreak=”toFit” the contentBounds width does not include the trailing whitespace.
- Fix when the TextLine is INVALID and cannot be used to access the current state of the TextBlock.

Thanks. Can you tell us if this will be included in a Flex SDK – and which current SDKs this is compatible with?
