This release contains two breaking changes: the removal of the env_logger and trace_logger features. Below are the suggested migration paths:
env_logger: users should use tracing_subscriber::fmt::Subscriber or tracing_subscriber::fmt::Layer with the Targets or EnvFilter filters instead.trace_logger: users should use the tracing crate's “log” feature flag instead.env_logger feature. This removes the dependency on the unmaintained atty crate, resolving the security advisory GHSA-g98v-hv3f-hcfr/RUSTSEC-2021-0145. (#2771)trace_logger feature.
