+## [1.0.0] - 2026-02-15
+
+### Node.js Compatibility
+
+QMD now runs on both **Node.js (>=22)** and **Bun**. Install with `npm install -g @tobilu/qmd` or `bun install -g @tobilu/qmd` — your choice. The `qmd` wrapper auto-detects Node.js via `tsx` and works out of the box with mise, asdf, nvm, and Homebrew installs.
+
+### Performance
+
+- **Parallel embedding & reranking** — multiple contexts split work across CPU cores (or VRAM on GPU), delivering up to **2.7x faster reranking** and significantly faster embedding on multi-core machines
+- **Flash attention** — ~20% less VRAM per reranking context, enabling more parallel contexts on GPU
+- **Right-sized contexts** — reranker context dropped from 40960 to 2048 tokens (17x less memory), since chunks are capped at ~900 tokens
+- **Adaptive parallelism** — automatically scales context count based on available VRAM (GPU) or CPU math cores
+- **CPU thread splitting** — each context runs on its own cores for true parallelism instead of contending on a single context
+
+### GPU Auto-Detection
+
+- Probes for CUDA, Metal, and Vulkan at startup — uses the best available backend
+- Falls back gracefully to CPU with a warning if GPU init fails
+- `qmd status` now shows device info (GPU type, VRAM usage)
+
+### Test Suite
+
+- Tests split into `src/*.test.ts` (unit), `src/models/*.test.ts` (model), and `src/integration/*.test.ts` (CLI/integration)
+- Vitest config for Node.js; bun test still works for Bun
+- New `eval-bm25` and `store.helpers.unit` test suites
+
+### Fixes
+
+- Prevent VRAM waste from duplicate context creation during concurrent loads
+- Collection-aware FTS filtering for scoped keyword search
