| Identifier | Meaning | Where to check |
|---|---|---|
| Docs v0.1 | This documentation website’s version. | Header and docs package.json; not an engine release. |

The latest release observed on 12 October 2026 was v0.5-Pre-Alpha; this is a verified repository tag, not a version invented from the Docs v0.1 header. Release assets may encode a different packaging version. Source implementation can be newer than a released binary: this audit uses engine commit 017db99b7025eeda96acf21967664153a2df0795.
Engine and API changes
Read the actual release notes before upgrading. This page does not fabricate a changelog or promise that older installers support every currently documented API. Keep backups of authored projects and review schema migration/compatibility notes. Feature status lists current restrictions, including input, audio, UI and export.
Documentation maintenance
Only one published docs version is maintained here. A historical archive/version selector is unnecessary until multiple versions exist. When engine behavior changes, update the published docs and matching engine-local guide, record the reviewed commit, and preserve old route aliases. See Documentation maintenance.
