### Release Notes

This is a patch release that fixes an issue with launching novelWriter via a project file on Windows, adds an alert when the spell check dictionary cannot be loaded, handles headings in HTML manuscripts the same way as for documents, and updates the documentation on how heading levels are handled in the manuscript build process.
