We recommend updating to the latest agent version as soon as it's available. If you can't upgrade to the latest version, update your agents to a version no more than 90 days old. Read more about keeping agents up to date.
See the New Relic Ruby agent EOL policy for information about agent releases and support dates.
Version 9.3.1 of the agent fixes
Bugfix: Fix NewRelic::Agent.require_test_helper
Version 9.3.0 of the agent made a change to the files distributed with the gem. This change unintentionally broke the
NewRelic::Agent.require_test_helperAPI by removing the
test/agent_helper.rbfile. The file has been added back to the gem. This change also removes the
lib/new_relic/build.rbfile from the list because it is no longer created with our current release process.
Source Documentation: update the Rack spec URL
Community member @olleolleolle noticed that our source code was referencing a now defunct URL for the Rack specification and submitted PR#2121 to update it. He also provided a terrific recommendation that we automate the checking of links to proactively catch defunct ones in future. Thanks, @olleolleolle!
