# Changelog ## 6.0.0 (unreleased) This independent major version identifies the compatibility modernization. Existing public APIs remain the compatibility target; documented historical differences and release gates still apply. - TypeScript subsystems and generated public declarations; preserve root APIs and offer precise /runtime types. - Lifecycle, source/event ownership, components, subtitles, playback/display and accessibility fixes; historical consumer matrix retained. 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), [types/README.md](./types/README.md). This entry records local preparation. Candidate contents, browser/device evidence and publication still require their release checks.
