atlas-debug with stash version 2.10.1 does not have Developer Toolbar

I am working on a stash plugin and find the developer toolbar, specifically, the FastDev feature, extremely useful.

In a clean, example plugin, created with atlas-create-stash-plugin, with stash version set to 2.9.4 in pom.xml, I do see the Developer Toolbar at the bottom when opening the page. See attachment "Screen Shot 2014-01-08 at 4.41.03 PM.png".

When using the most recent, non-specified version, stash 2.10.1, there is no Developer Toolbar.

How can this functionality be restored?

When I log into 2.10.1 as the admin user, I can see the FastDev (and other) plugins have been enabled.
