In 2005 Tesseract was open sourced by HP. From 2006 until November 2018 it was developed by Google.
The latest stable version is **[5.0.0](https://github.com/tesseract-ocr/tesseract/releases/tag/5.0.0)**, released on November 30, 2021.
Major version 5 is the current stable version and started with release
[5.0.0](https://github.com/tesseract-ocr/tesseract/releases/tag/5.0.0) on November 30, 2021.
Newer minor versions and bugfix versions are available from
[GitHub](https://github.com/tesseract-ocr/tesseract/releases/).
Latest source code is available from [main branch on GitHub](https://github.com/tesseract-ocr/tesseract/tree/main).
