1.5.1, and shouldn't negatively impact any extensions or the site.
Played around with all the major parts of the site. Didn't see any
problems at all.
Built static media for a release. All looked fine.
Built some extensions using less and RB's option settings. It all

Can we use a non-minified version here for debuggability?
