MongoDB in Meteor missing $max operator

Meteor seems to be missing the $max update operator.

I'm following the documentation here in the meteor mongo shell:

meteor:PRIMARY> db.vesrion()
2.4.9
meteor:PRIMARY> db.scores.insert({ _id: 1, highScore: 800, lowScore: 200 })
meteor:PRIMARY> db.scores.find()
{ "_id" : 1, "highScore" : 800, "lowScore" : 200 }
meteor:PRIMARY> db.scores.update( { _id: 1 }, { $max: { highScore: 950 } } )
Invalid modifier specified $max

Is there something I'm doing wrong? I can simulate the $max behavior by adding $lt clauses to my update condition, but it's clunky and doesn't work well if I also want to update other fields (for example, increment numGamesPlayed by 1 while also updating highScore).

There's nothing you're doing wrong, the problem is that the $max update operator was added in 2.6.

If you click the 2.6 (current) in the upper left of that doc page and select version 2.4 docs instead you'll see that $max is not there.

The best reference I can find is in the 2.6 release notes.
