Maturity and compatibility

A version label is part of the API contract. Core, Torch, JAX, and Fields are classified beta and currently use release-candidate versions. Other retained packages are explicitly alpha.

Working with prereleases

Pin exact versions, use isolated environments, and retain a small numerical regression for the workload you depend on. Shape conventions, configuration types, solver behavior, and backend availability may change between prereleases.

The package explorer exposes maturity filters. The installation guide gives exact commands, and current release metadata describes the family documented here.

A successful backend test does not establish support on every hardware accelerator or every framework version. Record the environment that produced your result.
