I just started now cef2go and it looks fantastic. Thanks to the detailed instructions I got the basic examples running, on Mac OS X Yosemite, and even go 1.4.2 (64 bit). erros I saw only when trying to access context menu, but I think this is mentioned somewhere on github issues. However for CEF, the instructions say we have to use exactly CEF 3 branch 1750 revision 1625. That is chrome 33. Any specific reason for sticking to that ? What needs to be considered or changed or whatever, for using a newer CEF build ?
