 ### Maximum Number of NVUE Revisions
 
 Cumulus Linux includes an option to set the {{<link url="NVUE-CLI/#maximum-revisions-limit" text="maximum number of revisions">}} after which NVUE deletes older revisions automatically. The default setting is 100. If you upgrade to Cumulus Linux 5.16 from 5.12 or earlier, the first time you run `nv set` or `nv unset` commands, NVUE deletes older revisions if the number of revisions on the switch is greater than 100.
