-OCRmyPDF is a Python 3 application and library that adds OCR layers to PDFs.
+OCRmyPDF is an application and library that adds text "layers" to images

+is contained in images. It is written in Python. OCRmyPDF supports plugins

+=======
+
+-  Fixed build failure for the combination of PyPy 3.6 and pikepdf 3.0. This
+   combination can work in a source build but does not work with wheels.
+-  Accepted bot that wanted to upgrade our deprecated requirements.txt.
+-  Documentation updates.
+-  Replace pkg_resources and install dependency on setuptools with
+   importlib-metadata and importlib-resources.
+-  Fixed regression in hocrtransform causing text to be omitted when this
+   renderer was used.
+-  Fixed some typing errors.
