 It is possible to ensure different types of unique args based on context. I can't vouch for the below example but see [#203](https://github.com/mhenrixon/sidekiq-unique-jobs/issues/203) for the discussion.

 class UniqueJobWithFilterMethod

 For sidekiq versions before 5.1 a `sidekiq_retries_exhausted` block is required per worker class. This is deprecated in Sidekiq 6.0
 
 ```ruby
 class MyWorker
   sidekiq_retries_exhausted do |msg, _ex|
-    digest = msg['unique_digest']
-    SidekiqUniqueJobs::Digests.delete_by_digest(digest) if digest
+    digest = msg['lock_digest']
+    SidekiqUniqueJobs::Digests.new.delete_by_digest(digest) if digest
   end
 end
 ```
 
 Starting in v5.1, Sidekiq can also fire a global callback when a job dies:
 
 ```ruby
 Sidekiq.configure_server do |config|
   config.death_handlers << ->(job, _ex) do
-    digest = job['unique_digest']
-    SidekiqUniqueJobs::Digests.delete_by_digest(digest) if digest
+    digest = job['lock_digest']
+    SidekiqUniqueJobs::Digests.new.delete_by_digest(digest) if digest
   end
 end
 ```
