 ## [Unreleased]
 
+## [0.7.5] — 2026-04-10
+
+### Added
+- **GraphRAG hybrid retrieval (KS61-KS64):** Full hybrid GraphRAG pipeline with label-graph navigation, 14 MCP tools, 517 tests
+- **GraphRAG Viz MVP (KS65):** Tauri + Sigma.js graph visualization app with 3 daemon endpoints and LOD architecture
+- **Schema-driven fact extraction (KS67):** LLM-based structured extraction with supersession for knowledge updates; 80% micro-benchmark recall
+- **Entity unification (KS73):** EntityFrame, EntityId-based supersession for structured entity tracking
+- **Configurable embedding (KS75):** EmbeddingProvider trait with 10 fastembed models and OpenAI API support
+- **Universal prompt (KS76):** Single prompt template for all reader models (no per-model tuning); temporal boost and 5-signal importance scoring
+- **Temporal boost (KS76):** Temporal-aware retrieval weighting for time-sensitive queries
+- **Multiplicative supersession demotion (KS78):** Superseded memories receive 0.40x multiplicative penalty (configurable)
+- **12 MCP tools:** Added `memory_graph`, `memory_related`, `memory_get` for graph navigation; `config_set` and `persist` for management
+
+### Changed
+- **MCP tool count:** 9 to 12 tools (graph navigation + management tools)
+- **Benchmark results:** 19/20 seeded micro-benchmark, 5/5 abstention, 3/3 NR, 24.2% LME-S (GPT-4o judge)
+- **Default reader model:** qwen2.5:1.5b for consolidation
+
+### Fixed
+- **Persistence format bug (Issue #16):** Format version mismatch causing MCP store/echo to fail
+- **KU-3 knowledge update (KS77):** Fixed retrieval for updated knowledge entries
+- **Temporal label dedup trap (KS77):** Prevent adverse dedup interaction when parent has temporal content
+- **Child memory pipeline rewrite (KS69):** Consolidation redesign fixing IE-1 and KU-1 categories
+- **Superseded_count declaration (KS78):** Variable declared in both temporal and standard code paths
+

 Key design: the `EchoEngine` is lazily initialized on first tool call. The server starts in milliseconds; fastembed model loading (a few seconds) is deferred until a memory operation is actually requested.
