Ruby agent v3.18.0.329

v3.18.0

• Ruby 2.4.0 support

  The agent is now tested against the official release of ruby 2.4.0, excluding incompatible packages.

• Agent-based metrics will not be recorded outside of active transactions

  The agent has historically recorded metrics outside of a transaction. In practice, this usually occurs in applications that run background job processors. The agent would record metrics for queries the background job processor is making between transactions. This can lead to display issues on the background overview page and the presence of metrics generated by the background job processor can mask the application generated metrics on the database page. The agent will no longer generate metrics outside of a transaction. Custom metrics recorded using NewRelic::Agent.record_metric will continue to be recorded regardless of whether there is an active transaction.

• Include ControllerInstrumentation module with ActiveSupport.on_load

  The agent will now use the on_load :action_controller hook to include the ControllerInstrumentation module in to both the Base and API classes of ActionController for Rails 5. This ensures that the proper load order is retained, minimizing side-effects of having the agent in an application.

• Ensure values for revisions on Capistrano deploy notices

  Previously, running the task to look up the changelog could generate an error, if there weren't previous and current revisions defined. This has now been fixed. Thanks Winfield Peterson for the contribution!

• External Segment Rewrites

  The agent has made internal changes to how it represents segments for external web requests.
