Yeah, my bad.

Yeah, makes sense.

Very good for me, I was afraid you were going to say something like the
end of September 2011. :)

I wonder how everything will work with FriBiDi, since currently my flow
is:
Split to paragraphs -> Get bidi attributes per paragraph -> split to
lines -> shape -> reorder.
But with ligatures support, the string indexes will change, right? (a
couple of codepoints will merge into one), so unless you'll pad with
zero-width-space/zero-width-joiner/zero-width-non-joiner or something to
keep the previous byte positions I won't be able to use the previous
calculated BiDi data and will have to recalc.

Thanks a lot,
Tom.
