We recently update our version of the node native mongo driver for the upcoming Meteor 1.4 release.

Although it's not documented what the default value for `applySkipLimit` is (http://mongodb.github.io/node-mongodb-native/2.1/api/Cursor.html#count) it appears that it's changed from `false` to `true` some time between version 1.4.39 and 2.1.18.

I'm not sure if it's an intentional change, and it's inconsistent with the commandline `mongo` shell's behaviour, AFAICT.

I couldn't find any documentation detailing this change either.
