-- #6267 - memory leak in SentrySpanProcessor by @volodkindv in [#6271](https://github.com/getsentry/sentry-python/pull/6271)
+
+  Previously, we'd attempt to serialize any `Sequence` by walking through it by calling its `__iter__` function.
+  We've now changed the serializer to only serialize built-in sequences (like lists, tuples, and sets) to avoid
+  triggering side-effects from custom `__iter__` implementations.
+
+  This might mean some objects might be serialized differently. If you want to continue serializing a specific
+  custom sequence class, you can register it via `sentry_sdk.serializer.add_repr_sequence_type` (see
+  [here](https://github.com/getsentry/sentry-python/blob/54f768680cad8a40ab97be4dddd16c12c9cba493/sentry_sdk/serializer.py#L60-L61)).
