Upgrading

September 16, 2020
.NET agent v8.32.0.0

New Features

  • Proxy Password Obfuscation Support
    Agent configuration supports the obfuscation of the proxy password. The New Relic Command Line Interface (CLI) may be used to obscure the proxy password. The following documentation describes how to use an obscured proxy password in the .NET Agent configuration.
  • MySqlConnector Support
    The MySqlConnector ADO.NET driver is instrumented by default. Fixes #85 and implements this suggestion.
  • Nullable Reference Type support in the API
    Enables nullable reference types that are part of the C# 8.0 language specification and updates the signatures of API methods accordingly. There should be no required changes in API usage.
  • Improved Support for NetTCP Binding in WCF Instrumentation
    When the NetTCP Binding type is used in Windows Communication Foundation (WCF), the Agent will now send and receive trace context information in support of Distributed Tracing (DT) or Cross Application Tracing (CAT). Implements #209.

Fixes

  • Fixes an issue that may cause InvalidCastException due to an assembly version mismatch in Mvc3 instrumentation.
  • Fixes an async timing issue that can cause the end time of Task-returning methods to be determined incorrectly.

.NET agent v8.31.0.0

New Features

  • Expected Errors Support
    Certain errors that are expected within the application may be identified so that they will not be counted towards the application's error rate and Apdex Score. Only errors that truly affect the health of the application will be alerted on. Please review the following documentation for details on how to configure Expected Errors.

  • Ignored Errors Enhancements
    Certain errors may be identified in configuration so that they will be ignored. These errors will not be counted towards the application's error rate, Apdex score, and will not be reported by the agent. Please review the following documentation for details on how to configure Ignored Errors.

    • New configuration element <ignoreMessages>supports filtering based on the error message.
    • Please note that the <ignoreErrors> configuration element has been deprecated and replaced by <ignoreClasses>. The .NET Agent continues to support this configuration element, but its support may be removed in the future.

Fixes

  • Garbage Collection Performance Metrics for Windows
    Fixes an issue where Garbage Collection Performance Metrics may not be reported for Windows Applications.
  • Maintaining newrelic.config on Linux package upgrades
    Fixes an issue where newrelic.config was being overwritten when upgrading the agent via either rpm/yum (RedHat/Centos) or dpkg/apt (Debian/Ubuntu).

Upgrading

July 16, 2020
.NET agent v8.30.0.0

New Features

  • The .NET agent is now open source!
    The New Relic .NET agent is now open source! Now you can view the source code to help with troubleshooting, observe the project roadmap, and file issues directly in this repository. We are now using the Apache 2 license. See our Contributing guide and Code of Conduct for details on contributing!

Fixes

  • Memory usage reporting for Linux
    Fixes issue where applications running on Linux were either reporting no physical memory usage or using VmData to report the physical memory usage of the application. The agent now uses VmRSS through a call to Process.WorkingSet64 to report physical memory usage. See the dotnet runtime discussion and the proc man pages for more details about this change.
  • Infinite Tracing performance
    Fixes issue where the agent may consume too much memory when using Infinite Tracing.
  • .NET 5 support
    Fixes issue with applications running on .NET 5 that prevented instrumentation changes at runtime (either though editing instrumentation XML files or through the Live Instrumentation editor Beta).

Upgrading

June 25, 2020
.NET agent v8.29.0.0

New Features

  • Additional Transaction Information applied to Span Events When Distributed Tracing and/or Infinite Tracing are enabled, the Agent will now incorporate additional information from the Transaction Event on to the root Span Event of the transaction. The following items are affected:

    1. Request Parameters request.parameter.*
    2. Custom Attribute Values applied to the Transaction via API Calls AddCustomParameter and ITransaction.AddCustomAttribute.
    3. request.uri
    4. response.status
    5. host.displayName
  • Security Recommendation Review your Transaction Attributes configuration. Any attribute include or exclude settings specific to Transaction Events, should be applied to your Span Attributes configuration or your Global Attributes configuration.

Fixes

  • Fixes issue where updating custom instrumentation while application is running could cause application to crash.
