API

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

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.
