There were some notable bug fixes between those versions. We are still far behind the current version (1.3.0). For the node stuff, I used npm update. Then for static/third/handlebars/handlebars.runtime.js, I copied the node version then added back the copyright. (imported from commit 59bcd2c52540ff88bba2f90cced809cfcb8cd92b)
