Geocouch couchdb1.3.x.tar.gz checksum changed

#1

It looks like the contents of the couchdb1.3.x.tar.gz release file of GeoCouch published on GitHub have changed at some point. Is this expected? This is the file at https://github.com/couchbase/geocouch/archive/couchdb1.3.x.tar.gz.

As of June 15 2014, the SHA256 checksum for couchdb1.3.x.tar.gz was:
0f678b5b79f5385c5c11349b662bb897047c72e8056dfb19f0f1e484d9348953
(This can be picked up from the Mac Homebrew formula; its build system verified the SHA sum on June 15 2014, while preparing this commit: https://github.com/Homebrew/legacy-homebrew/commit/e0e876b9080d9e59f8d5538ea5e8c71af1736f86)

As of today, April 19, 2016, the SHA256 checksum for couchdb1.3.x.tar.gz is:
1bad2275756e2f03151d7b2706c089b3059736130612de279d879db91d4b21e7
(This is from me downloading it and running shasum on it manually on OS X 10.9.)

Was this file republished at some point? Are its contents expected to be different from the 2014 version?

Cheers,
