Version: v1.0.0

Zova v1.0.0

Zova 1.0.0 establishes stable native 1.x API and storage-compatibility contracts for embedded SQL, binary KV, objects, exact vectors, graphs, and transaction-aware application notifications.

Major additions since v0.26.1​

  • First-class in-memory databases across native bindings.
  • Transactional binary key-value storage with atomic batches, namespace operations, and high-level binding coverage.
  • Explicit same-process app events with commit, rollback, savepoint, bounded-queue, and overflow semantics.
  • Non-mutating format probing and explicit copy-forward migration through the CLI, C ABI, Rust, Python, Go, and JavaScript.
  • A fixed 1 MiB streaming object profile, expanded streaming/range APIs, and format-11 object schemas.
  • Experimental zova-wasm browser SQL and KV in memory or named OPFS storage.
  • Target-specific generated-C Rust companion crates, so supported Rust consumers need a C compiler but not Zig or build-time downloads.
  • Windows x64 Python wheels alongside Linux and macOS. CPython 3.13 stable-ABI wheels support Python 3.13 and 3.14; no source distribution is published.

Stable 1.x contract​

Package and C ABI identity are 1.0.0. Documented native APIs preserve ownership, error categories, transaction semantics, deterministic ordering, and documented thread-safety guarantees throughout 1.x.

Opaque-key graph topology, payload, scan, and fresh-build sessions remain supported low-level C ABI and raw zova-sys capabilities. High-level bindings intentionally do not wrap them. Extension authoring and the separate browser API remain experimental.

Storage compatibility​

The current storage format is 11. Format-11 release-candidate databases need no migration. Released v0.26.1 format-9 databases and retained format-10 databases migrate explicitly into a new format-11 destination. Opening never silently migrates, the source remains unchanged, and downgrades are unsupported.

Distribution​

Native packages use 1.0.0 across Cargo, PyPI, npm, and Go. npm publishes zova-js, its native companions, and zova-wasm under latest. The Go module tag is bindings/go/v1.0.0.

Vector search remains exact. Notifications are same-process events rather than a durable queue. WASM exposes experimental SQL/KV rather than full native parity, and OPFS remains subject to browser storage policy.
