Update your agent

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 your agent up to date. See the New Relic .NET agent EOL policy doc for information about agent releases and support dates.
