From f9ef45798719254ce66b6374c5f803b04ec86721 Mon Sep 17 00:00:00 2001 From: Clint Byrum Date: Fri, 31 Jan 2014 11:05:09 -0800 Subject: Remove image parameter changing from merge The merge tool originally was meant to merge somewhat different things, and thus this was helpful in the early versions. However, at this point we want parameters to be more stable and we don't generally merge things that have their own image parameter. Meanwhile this feature caused problems as we change resource names. This is a backward incompatible change of default behavior, but the old behavior can be had again by passing --change-image-params.
