Agent raises an AttributeError on Python 3 when using WSGI overrides with multiple app names
When using WSGI environ overrides to specify multiple app names as described in the docs https://docs.newrelic.com/docs/agents/manage-apm-agents/app-naming/use-m... the agent will raise an AttributeError. This error has been corrected.
Agent raises an AttributeError exception under rare conditions when halting a trace

Agent raises a RuntimeError exception under particular conditions when using the Tornado r3 instrumentation
