New Relic Ruby Agent Release Notes

v6.6.0

• Bugfix for ActionCable Instrumentation

  Previous versions of the agent sometimes caused application crashes with some versions
  of ActionCable. The application would exit quickly after startup with the error:
  uninitialized constant ActionCable::Engine.

  Version 6.6.0 of the agent no longer crashes in this way.

• Handling of disabling Error Collection

  When the agent first starts, it begins collecting Error Events and Traces before
  fetching configuration from New Relic. In previous versions of the agent, those
  events or traces would be sent to New Relic, even if Error Collection is disabled in
  the application's server-side configuration.

  Version 6.6.0 of the agent drops all collected Error Events and Traces if the
  configuration from the server disables Error Collection.

v6.5.0

• Change to default setting for ActiveRecord connection resolution

  Due to incompatibilities between the faster ActiveRecord connection resolution
  released in v6.3.0 of the agent and other gems which patch ActiveRecord,
  backport_fast_active_record_connection_lookup will now be set to false by default.
  Because it results in a significant performance improvement, we recommend customers
  whose environments include ActiveRecord change this setting to true
  unless they are using other gems which measure ActiveRecord performance, which may
  lose functionality when combined with this setting. If unsure whether to enable
  backport_fast_active_record_connection_lookup, we recommend enabling it in a
  development environment to make sure other gems which patch ActiveRecord are still
  working as expected.

• Bugfix for ActiveStorage instrumentation error

  Version 6.4.0 of the agent introduced a bug that interfered with ActiveStorage
  callbacks, resulting in the agent being unable to instrument ActiveStorage operations.
  ActiveStorage segments are now correctly recorded.

• Bugfix for ActiveRecord 4.1 and 4.2 exception logging

  Version 6.3.0 of the agent introduced a bug that prevented ActiveRecord versions 4.1
  and 4.2 from logging exceptions that occurred within a database transaction. This
  version of the agent restores the exception logging functionality from previous agent
  versions.
