 # Changelog
 
+## Unreleased
+
+### Fixes
+
+- Order breadcrumbs by the timestamp they carry rather than by when they were created in the current process, so breadcrumbs restored from disk or handed over by a hybrid SDK no longer sort as if they had just happened ([#6097](https://github.com/getsentry/sentry-java/pull/6097))
+
 ## 8.56.0
 
 ### Behavioral Changes
