# Changelog ## 2.0.0 (unreleased) This independent major version identifies the compatibility modernization. Existing public APIs remain the compatibility target; documented historical differences and release gates still apply. - Typed VTT parsing, sprite lifecycle and cleanup. - Preserve published root types and precise /runtime; document supported old-core combinations and name conflicts. Internal dependencies and public entrypoints retain their documented compatibility boundaries. No new core-major peer restriction is introduced. Implementation and migration details: [README.md](./README.md), [ARCHITECTURE.md](./ARCHITECTURE.md). This entry records local preparation. Candidate contents, browser/device evidence and publication still require their release checks.
