+## Feature updates and improvements
+
+### Logging
+
+- **Better log readability**: Added `[seqera-fusion]` prefix to console logs for easier identification in mixed output environments.
+- **Improved error messages**: Added more context and clearer wording to cloud provider errors, including better messages for archived/cold storage objects.
+
+## Bug fixes
+
+### AWS

+- **Fixed misleading "file not found" errors**: Changed permission errors (403 Forbidden) from cloud providers to display as "Permission denied" instead of incorrectly showing "No such file or directory" (#1068).
+
+### General
+
+- **Cloud errors now log properly**: Fixed an issue where cloud service errors were silently treated as simple "file not found" cases instead of logging and reporting properly (#1077).
