July 30, 2018
.NET agent v8.4.880.0

Download URLs

Download the appropriate release for your New Relic .NET agent:

https://download.newrelic.com/dot_net_agent/previous_releases

New Features

  • SQL query parameter values can now be captured on Slow SQL Traces. This feature can be enabled with the new configuration option datastoreTracer.queryParameters. The transactionTracer.record_sql configuration option must also be set to raw. See documentation here. This feature should be used with caution as it can lead to the capture of sensitive data. High-security mode prevents the use of this feature. Windows support only. Linux support coming soon.
  • [.NET Framework] Adds support for tracking async transactions when .ConfigureAwait(false) is used from async controller actions in ASP.NET MVC applications.
  • [.NET Core] Adds support for .NET Core 2.1. Support for .NET Core 2.1 requires at least CLR version 2.1.3 and tiered compilation must not be enabled.

Fixes

  • [.NET Core] Fixes issue where status code based errors would be reported instead of the actual noticed Exception. This most commonly occurred with errors noticed in the ExceptionHandlerMiddleware (app.UseExceptionHandler(...)).
  • Fixes an issue where only the first request parameter is captured when request.parameters.* attributes are added to an include list.

Notes

  • We will be removing the core_20 directory from the download site the week of September 3rd, 2018 as it contains a deprecated version of the .Net Core agent. Please be sure to update any of your scripts that reference this location accordingly.
    • All downloads for the current version of the agent can be found in the latest_release directory on the download site.
    • Historical versions can be found in the previous_releases directory.

New Features

Fixes

.NET agent v8.1.712.0

New Features

  • [.NET Framework] The .NET Framework agent now supports instrumenting ASP.NET Core applications that are running on .NET Framework. The .NET Core specific agent is still required for instrumenting applications running on .NET Core.

Fixes

  • Fixed issue where deadlocks could occur in some situations when a ThreadAbortException was thrown within a client application.
  • Fixed issue where only the first transaction name set via API call to SetTransactionName() would be honored. Now, the last call to SetTransactionName() will be the name applied to the transaction.
  • [.NET Core 2.0] Fixed issue with the .NET Core agent on Windows where the CORECLR_PROFILER_PATH environment variable was not being expanded properly in certain deployment scenarios.
  • [.NET Framework] Fixed issue introduced in agent version 8.1.709.0 that caused some .NET Framework applications to throw the following exception: Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies.

.NET agent v8.1.709.0

重要

This release has been unpublished. Use version 8.1.712.0 or higher.

This version introduced a bug that could cause crashes for .NET Framework applications manually loading types from assemblies in the application domain. This includes enumerating custom attributes. The encountered error will appear like the following:

Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified

Fixes

  • Fixed issue where deadlocks could occur in some situations when a ThreadAbortException was thrown within a client application.
  • Fixed issue where only the first transaction name set via API call to SetTransactionName() would be honored. Now, the last call to SetTransactionName() will be the name applied to the transaction.

.NET agent v6.22.0.0

Fixes

  • Security Bulletin NR18-07: The agent will no longer run explain plans on MySQL queries which have multiple statements.

Upgrading

.NET agent v8.0.0.0

New Features

  • Adds stripExceptionMessages configuration option to the newrelic.config file. When enabled, this will remove error messages from errors that are reported to New Relic. This is the same behavior as having High-security mode enabled but can be used without High-security mode. The default value for this setting is false.

Fixes

  • Security Bulletin NR18-07: The agent will no longer run explain plans on MySQL queries that have multiple statements.

Other Changes

  • In order to increase security, disabling agent HTTPS communication via the service SSL configuration is no longer allowed.
  • WCF service parameters are now captured as request.parameters.* attributes and are no longer sent as service.request.* attributes.
  • Minimum version required for use in EU Datacenter.

Upgrading

February 20, 2018
.NET agent v7.1.229.0

New Features

  • Improved metadata collection for cloud providers. The agent now collects additional metadata when running in AWS, GCP, and Azure. This information is used to provide an enhanced experience when the agent is deployed on those platforms.

Fixes

  • Fixed an issue where transactions could be dropped when they included datastore segments and the following exception was logged: NewRelic ERROR: An exception occurred while doing some background work: System.NullReferenceException: Object reference not set to an instance of an object.
  • Fixed an issue where SOAP instrumentation would report System.Reflection.TargetInvocationException errors when a more specific error existed. Inner exceptions will now be reported when they exist.

Deprecation Warnings

The follow items are considered deprecated and will be removed with the upcoming 8.x major release:

  • Disabling agent HTTPS communication via the service SSL configuration will no longer be allowed starting in 8.x versions of the agent.
  • WCF service parameters will no longer be sent as service.request.* attributes starting in 8.x versions of the agent. These parameters will be sent in the form request.parameters.*.

.NET agent v6.21.0.0

Fixes

  • Security Bulletin NR18-04: Fixes issue where error messages were not fully being filtered out of error traces and error events when High-security mode was enabled.

Upgrading

January 22, 2018
.NET agent v7.0.2.0

New Features

  • Modifying custom instrumentation XML files can now be performed without having to restart the monitored application. Instrumentation updates will be applied ‘dynamically’ at runtime. This feature required functionality provided by new APIs introduced in .NET Framework 4.5 and newer, which this release also addresses (see ‘Framework Support’ section below).

Fixes

  • Security Bulletin NR18-04: Fixes issue where error messages were not fully being filtered out of error traces and error events when High-security mode was enabled.
  • Fixed an issue with automatic browser monitoring which could cause a stack overflow exception.
  • For custom instrumentation, the metricName parameter will be honored without needing to set transactionNamingPriority.
  • The scriptable installer will now successfully install and uninstall in scenarios where there is a space in the path to the installation files.

Framework Support

  • This release of the agent removes support for .NET Framework versions earlier than 4.5. See our community post about this from November of last year, for more details.
  • This is not an end of life for the 6.x agents (that support older .NET Frameworks), which will continue to work and report into New Relic.
