It looks like code is basically equivalent, but some build issues were fixed that may or may not affect you.
and the same could be said for 2.0.4.2 experimental versus 2.0.3.14 which is the stated 2.0.4.1 base.
Release: 2.0.4.1 (experimental) 2018-11-08 might have gone beta, but a Docker build bug needed fixing.
