Future behavior & Deprecation

Breaking Changes

During the 0.y.z phase, Rspack may include breaking changes only when upgrading the minor (y) version, and ensures backward compatibility when upgrading the patch (z) version. After reaching version 1.0.0, we will adhere to semver for version management.
