API

ProjectConversion methods now require an IProgress parameter, deprecated overloads without it:

• ProjectConversion.ConvertProject
• ProjectConversion.ConvertProjectContents
• ProjectConversion.ConvertProjectFile

Deprecated overload of ProjectConversion.ConvertSingle in favour of one requiring a Document

Please instead use ConvertSingle(Document document, TextSpan selected, ILanguageConversion languageConversion)
See the implementation of the deprecated method for help in migrating.
