   * Commit: https://review.openstack.org/#/c/281088/
 
+12. <version> <url> <md5hash> should be optional for command `openstack compute agent set`
+
+  Previously, the command was `openstack compute agent set <id> <version> <url> <md5hash>`,
+  whereas now it is: `openstack compute agent set <id> --version <version>
