Overall, I'm in favour of using Indexdata's repository. 

As Mark pointed out, 2.0.62 appears to be the latest version:
http://www.indexdata.com/zebra/doc/NEWS

You'll notice that 2.0.60 is where the tokenization bug was fixed: Fix ICU
phrase searches for terms split by ICU ZEB-664

You'll probably notice a big gap between 2.0.59 and 2.0.60. My emails to
Indexdata prompted the fix for 2.0.60. You may also notice "Allow @attr 2=102
for numeric index" in 2.0.62. I had noticed that relevance ranking didn't work
with a query containing a numeric index, so Indexdata fixed it. I don't think
it really affects the ranking much per se, but it prevents the Zebra error. 

Note also that you an now browse Zebra's code on Github:
https://github.com/indexdata/idzebra

I don't know if they accept pull requests, but I wouldn't be surprised if they
did.

Of course, I don't know if Indexdata will be doing much work on Zebra going
forward. I don't think they're answering the Zebra-list anymore:
http://lists.indexdata.dk/pipermail/zebralist/2016-May/002645.html

I think they're focusing their efforts on the FOLIO project these days. Tomas
mentioned some time ago that Indexdata considered Zebra a legacy project, and
that seems to be the case.

All the more reason to move to Elastic, I suppose, although I see the utility
of keeping Zebra around if only as a Z39.50 server. Makes you wonder if we
should be thinking about turning Zebra into an optional component once Elastic
takes over fully...
