+## [0.49.0] - 2026-03-28
+
+### Added
+
+- Proxy deep filters — strip orphaned tool_results (sidechains), deduplicate stale file reads, collapse failed retries
+- These target the real waste: 60K+ tokens of noise that was previously invisible to the proxy
+
+### Fixed
+
+- Proxy thinking filter: re-parse after signature strip was restoring removed thinking blocks, causing API 400
+- Proxy log: fixed double-dash in saved bytes, OPS now shows one decimal
+- `launch --proxy` chains correctly — starts pastewatch as upstream, not forward-proxy
+
 ## [0.48.3] - 2026-03-28
 
 ### Fixed
