Suggestion: Split the Changelog by Major Version for Better Navigation

[Vincent-Huang-2000]

One small maintainability suggestion: as CHANGELOG.md keeps growing, would it make sense to split older entries by major version (for example, CHANGELOG-v15.md, CHANGELOG-v16.md) and keep the main file focused on the current major version plus an index to the archives?

This could make the changelog easier to navigate and may also reduce the amount GitHub needs to render when viewing it in the browser, while still keeping the full release history available.

I’ve also found very large Markdown files can be a little sluggish to browse in GitHub’s web UI, especially on longer pages.
