Subject Re: 2.7.3 shipped without Snappy support
Date Sat, 01 Oct 2016 02:51:12 GMT
The way we build the bits as part of the release process changed quite a bit during that release
so there were some hiccups.

This seems like an oversight, though I tried to build them as close as possible to the releases
before 2.7.3. We can fix this for the next releases.

that this was an intentional change.
