# Changelog
All notable changes to Vestige will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [1.1.2] - 2025-01-27
### Fixed
- Embedding model cache now uses platform-appropriate directories instead of polluting project folders
- macOS: `~/Library/Caches/com.vestige.core/fastembed`
- Linux: `~/.cache/vestige/fastembed`
- Windows: `%LOCALAPPDATA%\vestige\cache\fastembed`
- Can still override with `FASTEMBED_CACHE_PATH` environment variable
---
## [1.1.1] - 2025-01-27
### Fixed
- UTF-8 string slicing issues in keyword search and prospective memory
- Silent error handling in MCP stdio protocol
- Feature flag forwarding between crates
- All GitHub issues resolved (#1, #3, #4)
### Added
- Pre-built binaries for Linux, Windows, and macOS (Intel & ARM)
- GitHub Actions CI/CD for automated releases
---
## [1.1.0] - 2025-01-26
### Changed
- **Tool Consolidation**: 29 tools → 8 cognitive primitives
- `recall`, `semantic_search`, `hybrid_search``search`
- `get_knowledge`, `delete_knowledge`, `get_memory_state``memory`
- `remember_pattern`, `remember_decision`, `get_codebase_context``codebase`
- 5 intention tools → `intention`
- Stats and maintenance moved from MCP to CLI (`vestige stats`, `vestige health`, etc.)
### Added
- CLI admin commands: `vestige stats`, `vestige health`, `vestige consolidate`, `vestige restore`
- Feedback tools: `promote_memory`, `demote_memory`
- 30+ FAQ entries with verified neuroscience claims
- Storage modes documentation: Global, per-project, multi-Claude household
- CLAUDE.md templates for proactive memory use
- Version pinning via git tags
### Deprecated
- Old tool names (still work with warnings, removed in v2.0)
---
## [1.0.0] - 2025-01-25
### Added
- FSRS-6 spaced repetition algorithm with 21 parameters
- Bjork & Bjork dual-strength memory model (storage + retrieval strength)
- Local semantic embeddings with fastembed v5 (BGE-base-en-v1.5, 768 dimensions)
- HNSW vector search with USearch (20x faster than FAISS)
- Hybrid search combining BM25 keyword + semantic + RRF fusion
- Two-stage retrieval with reranking (+15-20% precision)
- MCP server for Claude Desktop integration
- Tauri desktop application
- Codebase memory module for AI code understanding
- Neuroscience-inspired memory mechanisms:
- Synaptic Tagging and Capture (retroactive importance)
