Just checked the mongod from command line and it shows the version as
2016-05-03T17:29:27.133+0000 I CONTROL [initandlisten] db version v3.2.5
Which means that the version is 2.1.2 but the details is picking up data from static file?
The admin UI hasn't changed in any way, probably that's another reason I got a little confused. Btw any words on what could've (or is) the reason? Thanks
