Hi Ajit,

You can just use 1.8.2, as far as I know.

No, if it depends on anything from later than 1.8.1, it's a bug.
There was a significant performance bug when accessing compressed or
chunked data that was fixed in 1.8.3, but the somewhat slower results
using 1.8.2 were still correct.

That sounds good, and we'll announce such dependencies to the
address@hidden mailing list as well, if they are
required.
