+
+-  The Docker images (ocrmypdf, ocrmypdf-polyglot, ocrmypdf-tess4) are now based on Ubuntu 16.10 instead of Debian stretch
+
+   + This makes supporting the Tesseract 4 image easier
+   + This could be a disruptive change for any Docker users who built customized these images with their own changes, and made those changes in a way that depends on Debian and not Ubuntu

+======
 
 -  To prevent a `TIFF output error <https://github.com/python-pillow/Pillow/issues/2206>`_ caused by img2pdf >= 0.2.1 and Pillow <= 3.4.2, dependencies have been tightened
--  The Tesseract 4.00 simultaenous process limit was increased from 1 to 2, since it was observed that 1 lowers performance
+-  The Tesseract 4.00 simultaneous process limit was increased from 1 to 2, since it was observed that 1 lowers performance
 -  Documentation improvements to describe the ``--tesseract-config`` feature 
 -  Added test cases and fixed error handling for ``--tesseract-config``
 -  Tweaks to setup.py to deal with issues in the v4.4 release
