 New features
 ------------

--  New argument --tesseract-pagesegmode allows you to pass page segmentation arguments to Tesseract OCR.
+-  Lossless reconstruction: when possible, OCRmyPDF will inject text layers without 
+   otherwise manipulating the content and layout of a PDF page. For example, a PDF containing a mix
+   of vector and raster content would see the vector content preserved. Images may still be transcoded
+   during PDF/A conversion.  (``--deskew`` and ``--clean-final`` disable this mode, necessarily.)
+-  New argument ``--tesseract-pagesegmode`` allows you to pass page segmentation arguments to Tesseract OCR.
    This helps for two column text and other situations that confuse Tesseract.
+-  Added a new "polyglot" version of the Docker image, that generates Tesseract with all languages packs installed,
+   for the polyglots among us. It is much larger.
+
+Changes
+-------
+
+-  JPEG transcoding quality is now 95 instead of the default 75. Bigger file sizes for less degradation.

 -  Fixed an issue where OCRmyPDF failed to text that certain pages contained previously OCR'ed text, 
    such as OCR text produced by Tesseract 3.04
 -  Inserts /Creator tag into PDFs so that errors can be traced back to this project
--  Added new option --pdf-renderer=auto, to let OCRmyPDF pick the best PDF renderer. 
+-  Added new option ``--pdf-renderer=auto``, to let OCRmyPDF pick the best PDF renderer. 
    Currently it always chooses the 'hocrtransform' renderer but that behavior may change.
 -  Set up Travis CI automatic integration testing
