## [Unreleased]
## [0.1.0] - 2026-04-20
Initial open-source release of `libfossil`, a pure-Go implementation of the
Fossil SCM that reads and writes the same `.fossil` SQLite repository format.
### Added
- Repository lifecycle: create new repos and clone from existing ones.
- Working-tree operations: checkout and checkin.
- Timeline traversal over commits and events.
- Merge and rebase primitives.
- Diff and annotate (blame) over tracked content.
- Manifest parsing and content-addressed blob storage.
- Sync protocol client/server for pulling and pushing between repos.
- Observer interfaces for sync and checkout, allowing external hooks into
both network sync events and working-tree state transitions.
- SQLite driver abstraction with support for both `modernc.org/sqlite` (pure
Go) and `ncruces/go-sqlite3` (cgo-free, wasm-based) backends.
- Deterministic simulation test harness with BUGGIFY-style fault injection
for exercising concurrency and failure paths.
- OpenTelemetry observer provided as a separate submodule to keep the core
dependency footprint small.
- `wasip1/wasm` build target for running `libfossil` under WASI runtimes.
