| Description |
|
A standalone or replica set started with shardsvr currently does not write a featureCompatibilityVersion on clean startup. It should write a featureCompatibilityVersion 3.4 document. This is safe, since there will be no 3.6 features to strip out if the shard is added to an FCV=3.4 cluster. This is important, because in 3.6, we require the featureCompatibilityVersion document to be present. |
