[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.
