.changeset/rare-plants-shake.md (1)

1-5: Changeset looks good; scope and summary are appropriate for a patch.

Accurately documents the deprecation warning without implying an API break. No further edits needed.

41-41: Deprecation log placed before auth — confirm intent

Logging currently runs before the hasPermissionAsync guard and will record unauthorized attempts (which may add noise). If you only want to warn legitimate callers, move the deprecation log after the permission check; otherwise keep as-is. The deprecation path '/v1/livechat/department' matches existing conventions.

Proposed alternative (move after the guard):

async 'livechat:saveDepartment'(_id, departmentData, departmentAgents, departmentUnit) {
-    methodDeprecationLogger.method('livechat:saveDepartment', '8.0.0', '/v1/livechat/department');
     const uid = Meteor.userId();
     if (!uid || !(await hasPermissionAsync(uid, 'manage-livechat-departments'))) {
       throw new Meteor.Error('error-not-allowed', 'Not allowed', {
         method: 'livechat:saveDepartment',
       });
     }
+    methodDeprecationLogger.method('livechat:saveDepartment', '8.0.0', '/v1/livechat/department');
     return saveDepartment(uid, _id, departmentData, { upsert: departmentAgents }, departmentUnit);
}

6-6: Import of methodDeprecationLogger — canonical import confirmed

apps/meteor/app/lib/server/lib/deprecationWarningLogger.ts is the single implementation; saveDepartment.ts's import ('../../../lib/server/lib/deprecationWarningLogger') resolves to it and methodDeprecationLogger.method is referenced across the repo — no alternate re-exports detected in the provided search output.
