 ### Migrated Datadog Tracer From the `ddtrace` Gem to `datadog`
 
 The Datadog tracer now uses the `datadog` gem instead of the deprecated `ddtrace`.
+The `ddtrace` gem is still supported but emits a deprecation warning at load time.
+Support for `ddtrace` will be removed in Hutch 2.0.
+
+### Deprecated `SentryRaven` Error Handler
+
+`Hutch::ErrorHandlers::SentryRaven` now emits a deprecation warning and will be
+removed in Hutch 2.0. Use `Hutch::ErrorHandlers::Sentry` (backed by `sentry-ruby`) instead.
 
 ### Rails 8.x Compatibility
