• Add ::ActiveJob::Attributes for declaring typed attributes that persist across job serialization and deserialization. It is included by ::ActiveJob::Continuable but can also be used standalone.

  It uses the Active Model Attributes API to define typed, defaulted attributes on jobs. Attribute values are automatically included in the serialized job data and restored on deserialization, eliminating the need to manually override serialize and deserialize.

  This is especially useful with ::ActiveJob::Continuable, where a job may be interrupted and resumed and attributes are preserved across resumptions.

  class SubmitEnrollmentJob < ApplicationJob
    include ActiveJob::Continuable
  
    attribute :payment_token, :string
    attribute :billing_profile_id, :integer
  
    def perform(enrollment)
      step(:tokenize_payment_instrument) do
        self.payment_token = PaymentGateway.tokenize(enrollment.user.payment_instrument)
      end
  
      step(:create_billing_profile) do
        self.billing_profile_id = BillingProfileApi.create(customer_id: enrollment.user_id)
      end
  
      step(:submit_enrollment) do
        submission_id = EnrollmentApi.submit(enrollment, billing_profile_id)
        enrollment.update!(status: 'processing', submission_id: submission_id)
      end
    end
  end

• Allow retry_on wait procs to accept the error as a second argument.

  Procs with arity 1 continue to receive only the execution count.

  class RemoteServiceJob < ActiveJob::Base
    retry_on CustomError, wait: ->(executions, error) { error.retry_after || executions * 2 }
  
    def perform
      # ...
    end
  end

• Deprecate built-in backburner adapter.

• Jobs are now enqueued after transaction commit.

  This fixes that jobs would surprisingly run against uncommitted and rolled-back records.

  New Rails 8.2 apps (and apps upgrading to config.load_defaults "8.2") have config.active_job.enqueue_after_transaction_commit = true by default. Uncomment the setting in config/initializers/new_framework_defaults_8_2.rb to opt in.

• Un-deprecate the global config.active_job.enqueue_after_transaction_commit toggle for app-wide overrides. It was deprecated in Rails 8.0 (when the symbol values were removed) and made non-functional in 8.1. It now works as a boolean config again.
