ChangeLog

Starting in version 6.1:

MongoDB always enables journaling. As a result, MongoDB removes the storage.journal.enabled option and the corresponding --journal and --nojournal command-line options.

Starting in version 5.0:

MongoDB removes the --serviceExecutor command-line option and the corresponding net.serviceExecutor configuration option.

Starting in version 4.4:

MongoDB removes the --noIndexBuildRetry command-line option and the corresponding storage.indexBuildRetry option.

Starting in version 4.2:

MongoDB removes the deprecated MMAPv1 storage engine and the MMAPv1-specific configuration options:

Removed Configuration File Setting	Removed Command-line Option
`storage.mmapv1.journal.commitIntervalMs`
`storage.mmapv1.journal.debugFlags`	`mongod --journalOptions`
`storage.mmapv1.nsSize`	`mongod --nssize`
`storage.mmapv1.preallocDataFiles`	`mongod --noprealloc`
`storage.mmapv1.quota.enforced`	`mongod --quota`
`storage.mmapv1.quota.maxFilesPerDB`	`mongod --quotaFiles`
`storage.mmapv1.smallFiles`	`mongod --smallfiles`
`storage.repairPath`	`mongod --repairpath`
`replication.secondaryIndexPrefetch`	`mongod --replIndexPrefetch`
