 # Changelog
 
+## v3.10.10 (2026-05-25)
+
+**Context Normalizer Fix — Compaction Summary Preservation**
+
+### Bug Fixes
+- Fixed normalizer stripping ALL context on resumed sessions after compaction
+- Normalizer no longer auto-resets when compaction summary is present
+- Compaction summaries ("Auto-compacted: N earlier turns") are always preserved
+- Deduplicates consecutive identical `<goal_context>` messages (10→1)
+- Emergency reset now preserves compaction summaries
+- Previous behavior: after compaction reduced 1925→185 items, normalizer saw `n_tool_outputs == 0` and stripped to just `system + latest_user`, losing all context — model responded with "I don't have context"
+
+### hashlib Fix (v3.10.9 hotfix)
+- `_antigravity_normalize_context` crashed with `NameError: hashlib` on resumed sessions
+- Replaced SHA256 duplicate detection with string comparison
+
 ## v3.10.9 (2026-05-25)
 
 **Antigravity Overhaul — Context Normalizer, Claude Thinking Fix, Endpoint Lockdown**
