+ A new rendering option ``--pdf-renderer tess4`` exploits Tesseract 4's new text-only output PDF mode. See the documentation on PDF Renderers for details.
+ The ``--tesseract-oem`` argument allows control over the Tesseract 4 OCR
engine mode.
engine mode (tesseract's ``--oem``). Use ``--tesseract-oem 2`` to enforce the new LSTM mode.
+ Fixed poor performance with Tesseract 4.00 on Linux
- Fixed an issue that caused corruption of output to stdout in some cases
- Removed test for Pillow JPEG and PNG support, as the minimum supported version of Pillow now enforces this
- OCRmyPDF now tests that the intended destination file is writable before proceeding
- Significant code reorganization to make OCRmyPDF re-entrant and improve performance. All changes should be backward compatible for the v4.x series.
+ However, OCRmyPDF's dependency "ruffus" is not re-entrant, so no Python API is available. Scripts should continue to use the command line interface.
