Antti Korpi	6f535cb65d	Travis: stop testing on Node 0.10 + 0.12 They're breaking the build, because Mocha (a dependency) is using modern JS features.	2018-01-23 22:36:27 +01:00
Antti Korpi	ed27aa84ff	Fix 'root' deprecation warning This would previously be printed in part of the test log: (node:1628) [DEP0016] DeprecationWarning: 'root' is deprecated, use 'global' Apparently, the global object was once called root, and this assignment didn't have a `var`, so it was actually setting the global object. I do wonder why that didn't break anything, but this is clearly what was intended.	2018-01-23 22:35:49 +01:00
