Rails 8.1.2 (January 08, 2026)

• Fix ActiveJob.perform_all_later to respect job_class.enqueue_after_transaction_commit.

  Previously, perform_all_later would enqueue all jobs immediately, even if they had enqueue_after_transaction_commit = true. Now it correctly defers jobs with this setting until after transaction commits, matching the behavior of perform_later.

• Fix using custom serializers with ActiveJob::Arguments#serialize when ::ActiveJob::Base hasn't been loaded.

  Hartley McGuire

Rails 8.1.1 (October 28, 2025)

• Only index new serializers.

  Jesse Sharps

Rails 8.1.0 (October 22, 2025)

• Add structured events for Active Job:

  • active_job.enqueued
  • active_job.bulk_enqueued
  • active_job.started
  • active_job.completed
  • active_job.retry_scheduled
  • active_job.retry_stopped
  • active_job.discarded
  • active_job.interrupt
  • active_job.resume
  • active_job.step_skipped
  • active_job.step_started
  • active_job.step

• Deprecate built-in sidekiq adapter.

  If you're using this adapter, upgrade to sidekiq 7.3.3 or later to use the sidekiq gem's adapter.

• Remove deprecated internal SuckerPunch adapter in favor of the adapter included with the sucker_punch gem.

  Rafael Mendonça França

• Remove support to set ActiveJob::Base.enqueue_after_transaction_commit to :never, :always and :default.

  Rafael Mendonça França

• Remove deprecated Rails.application.config.active_job.enqueue_after_transaction_commit.

• ActiveJob::Serializers::ObjectSerializers#klass method is now public.

  Custom Active Job serializers must have a public #klass method too. The returned class will be index allowing for faster serialization.

• Allow jobs to the interrupted and resumed with Continuations

  A job can use Continuations by including the ::ActiveJob::Continuable concern. Continuations split jobs into steps. When the queuing system is shutting down jobs can be interrupted and their progress saved.

  class ProcessImportJob
    include ActiveJob::Continuable
  
    def perform(import_id)
      @import = Import.find(import_id)
  
      # block format
      step :initialize do
        @import.initialize
      end
  
      # step with cursor, the cursor is saved when the job is interrupted
      step :process do |step|
        @import.records.find_each(start: step.cursor) do |record|
          record.process
          step.advance! from: record.id
        end
      end
  
      # method format
      step :finalize
  
      private
        def finalize
          @import.finalize
        end
    end
  end

  Donal McBreen

• Defer invocation of ActiveJob enqueue callbacks until after commit when enqueue_after_transaction_commit is enabled.

  Will Roever

• Add report: option to ActiveJob::Base#retry_on and #discard_on

  When the report: option is passed, errors will be reported to the error reporter before being retried / discarded.

  Andrew Novoselac

• Accept a block for ActiveJob::ConfiguredJob#perform_later.

  This was inconsistent with a regular ActiveJob::Base#perform_later.

  fatkodima

• Raise a more specific error during deserialization when a previously serialized job class is now unknown.

  ::ActiveJob::UnknownJobClassError will be raised instead of a more generic NameError to make it easily possible for adapters to tell if the NameError was raised during job execution or deserialization.
