I used Tesseract for some projects a few years ago (version 2.x). It was already state-of-the-art in the specific task it is designed for, more or less on par with the best proprietary solutions. As others pointed out, Tesseract is only a specific part in a general OCR solution. I'm wondering how actively it is being developed. I see that the last release is from 2019. I also see, however, that there have been some version 5.x alpha releases published this year. Does anyone know what is happening inside the project?
