Release notes for model versions

Model versions now include a release_notes field. Each version can describe what changed — new features, bug fixes, optimizations, or breaking changes.

Why was this added

Previously, version numbers were the only way to distinguish between iterations of a model. If a model had 12 versions, there was no way to know what changed between version 8 and version 9 without digging into the model's external documentation. Release notes give version history the context it was missing.

What it looks like

Release notes are available when fetching a model's version history through the API.
