Changed
league/html-to-markdownis now constrained to^5.0instead of*.
The unbounded constraint permitted 2.x through 4.x, none of which this package is written against, and would have silently accepted a future 6.0 with breaking changes to the HtmlConverter API that RicherEditorServiceProvider calls directly.
Resolution is unchanged in practice: * already resolved to the newest release, and ^5.0 resolves that same 5.1.2. This narrows what Composer is permitted to install rather than moving anything, so an existing install will see no change on update.
