# Changelog
## 0.8.4
- Simplified CI/CD workflow triggers to avoid redundant post-merge runs.
- Added runner-aware `actions/cache@v4` protoc caching in CI, docs deploy, and release workflows.
- Pinned workflow protoc installation to `28.3` with cache-aware conditional setup.
## 0.8.3
- Added inclusion-first eligibility post-filtering to reduce exclusion-only false positives in trial matching.
- Applied cryptography dependency security updates and refreshed release artifacts.
- Tightened CLI/docs consistency around trial filter behavior and output contracts.
## 0.8.2
- Added location-level facility and geo post-filtering for more accurate trial site matching.
- Embedded git tag version metadata in the binary for reliable `biomcp version` output.
- Improved pagination and result-window handling across search command families.
## 0.8.1
- Expanded clinical-grade trial filtering with ~45 new search flags and validation rules.
- Added MCP tool auto-generation to reduce drift between CLI capabilities and server tool surface.
- Upgraded help/discoverability content and list-based guidance for agent-driven workflows.
## 0.8.0
Complete rewrite from Python to Rust. Single static binary, no runtime dependencies.
### Highlights
- Single-binary CLI and MCP server — no Python, no pip, no virtual environments
- 15 biomedical data sources, unified command grammar, compact markdown output
- 14 embedded skills (guided investigation workflows)
- MCP server (stdio + SSE) with tool and resource support
- HTTP proxy (`serve-http`) for multi-worker shared rate limiting
- Production installer with SHA256 verification (5 platforms)
- Progressive disclosure: search returns summaries, get returns full detail with selectable sections
- NCBI API key support for improved rate limits
- 429 retry with Retry-After backoff
