Release v1.6.0 introduces support for the following resources:
dynatrace_span_entry_point
dynatrace_span_capture_rule
dynatrace_span_context_propagation
dynatrace_resource_attributes
The REST API for OpenTelemetry Settings is still considered "Early Access" by Dynatrace, therefore it's possible that the HCL schema for the above resources might change slightly in the future. Existing `.'tf' files are however unlikely going to become invalid. It's rather possible that additional attributes may be getting introduced in future versions.
Release v1.7.0 will focus on configuring Dashboard Sharing and creating Environments using the Cluster API.
