PHP Agent (legacy) Release Notes

AppOptics agents are no longer receiving updates. The new SolarWinds Observability libraries are regularly updated with new features and improvements. If you are still relying on the AppOptics agents and your components are supported by the new libraries, consider migrating to SolarWinds Observability.

SolarWinds Observability Libraries are not compatible with AppOptics agents. Do not use a mix of SolarWinds Observability Libraries and AppOptics agents to instrument applications that are part of a distributed trace.
