A new version of the Amazon plugin for Packer was released today containing a subtle change that we consider to be breaking. Prior to the
v1.0.9 release the Amazon builders would include a default "Name" tag with the value "Packer Builder". As of v1.0.9 the builders will no longer add the default tag, and will only add tags to the instance if they have been defined within the build template. If you were relying on this default tag you will need to update your build template to include the tag or modify any processes that may be looking for the said tag.
