• Add a fast failure mode to ::ActiveSupport::ContinuousIntegration that stops the rest of the run after a step fails. Invoke by running bin/ci --fail-fast or bin/ci -f.

  Dennis Paagman

• Implement LocalCache strategy on ::ActiveSupport::Cache::MemoryStore. The memory store needs to respond to the same interface as other cache stores (e.g. ActiveSupport::NullStore).

  Mikey Gough

• Add a detailed failure summary to ::ActiveSupport::ContinuousIntegration.

  Mike Dalessio

• Introduce ::ActiveSupport::EventReporter::LogSubscriber structured event logging.

    def something(event)
      info { "Event #{event[:name]} emitted." }
    end
  end
