## Project status

### Versioning

The ORAS Go library follows [Semantic Versioning](https://semver.org/), where breaking changes are reserved for MAJOR releases, and MINOR and PATCH releases must be 100% backwards compatible.

### v2: stable

[![Go Reference](https://pkg.go.dev/badge/oras.land/oras-go/v2.svg)](https://pkg.go.dev/oras.land/oras-go/v2)

The version `2` is actively developed in the [`main`](https://github.com/oras-project/oras-go/tree/main) branch with all new features.

Examples for common use cases can be found below:

- [Copy examples](https://pkg.go.dev/oras.land/oras-go/v2#pkg-examples)
- [Registry interaction examples](https://pkg.go.dev/oras.land/oras-go/v2/registry#pkg-examples)
- [Repository interaction examples](https://pkg.go.dev/oras.land/oras-go/v2/registry/remote#pkg-examples)
- [Authentication examples](https://pkg.go.dev/oras.land/oras-go/v2/registry/remote/auth#pkg-examples)

If you are seeking latest changes, you should use the [`main`](https://github.com/oras-project/oras-go/tree/main) branch (or a specific commit hash) over a tagged version when including the ORAS Go library in your project's `go.mod`.
The Go Reference for the `main` branch is available [here](https://pkg.go.dev/oras.land/oras-go/v2@main).

To migrate from `v1` to `v2`, see [MIGRATION_GUIDE.md](./MIGRATION_GUIDE.md).

### v1: stable

[![Build Status](https://github.com/oras-project/oras-go/actions/workflows/build.yml/badge.svg?event=push&branch=v1)](https://github.com/oras-project/oras-go/actions/workflows/build.yml?query=workflow%3Abuild+event%3Apush+branch%3Av1)

[![Go Reference](https://pkg.go.dev/badge/oras.land/oras-go.svg)](https://pkg.go.dev/oras.land/oras-go)

As there are various stable projects depending on the ORAS Go library `v1`, the
[`v1`](https://github.com/oras-project/oras-go/tree/v1) branch
is maintained for API stability, dependency updates, and security patches.
All `v1.*` releases are based upon this branch.

Since `v1` is in a maintenance state, you are highly encouraged
to use releases with major version `2` for new features.
