+v10.2.0
+=======
+
+-  Update Docker image to use Ubuntu 20.04.
+-  Fixed issue PDF/A acquires title "Untitled" after conversion. (#582)
+-  Fixed a problem where, when using ``--pdf-renderer hocr``, some text would
+   be missing from the output when using a more recent version of Tesseract.
+   Tesseract began adding more detailed markup about the semantics of text
+   that our HOCR transform did not recognize, so it ignored them. This option is
+   not the default. If necessary ``--redo-ocr`` also redoing OCR to fix such issues.
+-  Fixed an error in Python 3.9 beta, due to removal of deprecated
+   ``Element.getchildren()``. (#584)
+-  Implemented support using the API with ``BytesIO`` and other file stream objects.
