 # Changelog
 
+## 2026-03-16 - 4.5.11 - fix(repo)
+no changes to commit
+
+
+## 2026-03-16 - 4.5.10 - fix(remoteingress-core)
+guard zero-window reads to avoid false EOF handling on stalled streams
+
+- Prevent upload and download loops from calling read on an empty buffer when flow-control window remains at 0 after stall timeout
+- Log a warning and close the affected stream instead of misinterpreting Ok(0) as end-of-file
+
 ## 2026-03-16 - 4.5.9 - fix(remoteingress-core)
 delay stream close until downstream response draining finishes to prevent truncated transfers
