Major Change
-
ALL
Null is being treated differently by the $gt and $lt operators between versions.
db.q.drop()
db.q.insert({"a" : { "a" : 1 } })
db.q.find( { "b" : { $lt : null } } ).itcount()
db.q.find( { "b" : { $gt : null } } ).itcount()
2.4.5: 1 doc per query
2.5.4-Pre: zero doc per query
Note
The following queries behave the same on both versions and return zero documents
db.q.find( { "b" : { $lte : null } } ).itcount()
db.q.find( { "b" : { $gte : null } } ).itcount()
