+# Changelog
+
+## [0.1.0] — 2025-09-13
+### Added
+- SQLite-backed snapshot library with content-defined chunking (FastCDC).
+- Deduplication by SHA-256 of chunks; optional Zstd compression.
+- End-to-end integrity checks: per-chunk hash and final file hash.
+- Transactions (WAL), basic integrity constraints, and triggers.
+- High-level API:
+  - `Storage`: `newSnapshot`, `getSnapshots`, `getSnapshot`, `removeSnapshots`, `setupCDC`, `getVersion`.
+  - `Snapshot`: `data()` (buffered) and streaming `data(void delegate(const(ubyte)[]))`, `remove()`, properties (`id`, `label`, `created`, `length`, `sha256`, `status`, `description`).
+- Tool to generate a Gear table for FastCDC (`tools/gen.d`).
