Back to Release Notes



WProofreader v3.0

  • Static proofread in dialog mode was replaced with a compact and intuitive floating one. Now the dialog collects only suggestions without extracting the whole text from the original text field.
  • The color of detected grammar-type errors changed from green to blue.

AI-based proofreading engine

  • AI-based engine outputs two types of suggestions: spelling and grammar. Suggested corrections will be flagged with red and blue underlines accordingly. Previously spelling suggestions were mixed with the classical dictionary-based spelling engine.
  • Added new option <Enabled>true</Enabled> to SpellEngineOptions tag that regulates if classical spell check engine should be enabled in parallel with AI-based engine.

Core & API

  • [GitHub#180] API | SCAYT | WProofreader: Alphabetical sorting of personal dictionary
