OK. I'll rebase on 106d710b and try to get the series out in a day or two. > So far I liked the per-object-type dictionary conjecture the > most, primarily because my gut feeling tells me that it would > involve the least amount of hassle in the interoperability area. Agreed, except I don't think its going to save us very much (~4%) and its enough of a change still to make things a little ugly. If the "true" dictionary compression idea has any value it may save us even more and make it easier to implement fast full text searching across files. But its definately more complex. So I'm going to shut up now. > But honestly speaking I am not looking forward to a packfile > format update at this moment.

I won't have enough time between now and the end of this month to create a dictionary pack that's even ready for pu, let alone next. I hope we see 1.4.3 before then. :-) -- Shawn.
