The documentation at https://www.dragonflydb.io/docs/managing-dragonfly/flags#--multi_exec_mode still lists --multi_exec_mode as a valid flag, but it has been fully removed from the codebase.

Timeline

• Passing --multi_exec_mode at startup will crash the application

Impact

When we tried to update our (pretty old) dragonfly instances to a newer version we had to hunt through the code why setting this flag didn't work anymore as both the docs, and the release notes do not state either the deprecation of this flag, or the removal of it.

Fix

• Remove the --multi_exec_mode entry from the flags documentation page
• Update the release notes of the release that included chore: fix data corruption bug dragonfly#6174 to reflect the (effectively breaking) change.
