+# REQ: Release v1.6.0

+## Background
+PR #36 (context optimization) merged to master. Need to publish npm v1.6.0 with all changes.
+
+## Changes in v1.6.0 (since v1.5.1)
+1. Two-tier summary length limits (soft 200 / hard 800)
+2. Minimum compress range (2000 chars)
+3. Step marker truncation (step-start skipped, step-finish ~50 chars)
+4. Nudge strengthening + directive consolidation guidance
+5. mark_block + unmark_block removed from model tools
+6. Auto-detect consumed blocks in compress (Plan B)
+7. Directive nudge range fix (anchorMessageId, visible range filter)
+8. GC simplified to hardcoded 100% fallback
+9. README updated (English + Chinese)
+
+## Version Bump
+- 1.5.1 → 1.6.0
