Also, I think that if you use java API, some package refactoring  has been done and is no more compatible with 0.16.4.
That was my only "problem" with that version.

We currently have an ES cluster in production using version 0.16.4.
We'd like to upgrade to 0.17.8. Is there anything in particular we need
to know ahead of time, or is it just a simple drop-in of the new
binaries (etc) as usual?
I've just done a 0.16.5 to 0.17.8, and it was fine.
Except: if you are using bool filters, then you may get errors. There
is a bug that is fixed in master.
