Breaking changesedit
  • We have some changes that are technically breaking changes. We made some helper classes internal that were never meant to be public. These are: Elastic.Apm.Helpers.AgentTimeInstant, Elastic.Apm.Helpers.ContractExtensions, Elastic.Apm.Helpers.ObjectExtensions, Elastic.Apm.Helpers.ToStringBuilder. None of these classes were documented or mentioned as part of the Public Agent API. We expect no usage of these classes outside the agent.

Breaking changesedit

We have some breaking changes in this release. We wanted to do these changes prior to our GA release and with this we hopefully avoid breaking changes in the upcoming versions.

  • For better naming we replaced the Elastic.Apm.All packages with Elastic.Apm.NetCoreAll #371
  • Based on feedback we also renamed the UseElasticApm() method in the Elastic.Apm.NetCoreAll package to UseAllElasticApm - this method turns on every component of the Agent for ASP.NET Core. #371
  • Our logger abstraction, specifically the IApmLogger interface changed: #389
  • To follow the Elastic Common Schema (ECS), we renamed our Tags properties to Labels. #416
