Migration guides
Turian follows semantic versioning: a new major version means at least one change that can break existing projects. Every major release gets a guide here describing exactly what changed, who is affected, and the steps to upgrade.
Minor and patch releases never require migration — you can skip any number of them and upgrade directly to the latest version, applying only the major-version guides in between (in order).
Turian 1.0.0 is the first release of the C# engine. Upgrading from it: 2.0.0. Projects made with the Zig engine, TurianZ, cannot be converted; see Turian and TurianZ.
