@ -15,6 +15,9 @@ wish to use some of its features for working with PDFs.
v11.3.2
=======
- Explicitly require pikepdf 2.0.0 or newer when running on Python 3.9. (There are
concerns about the stability of pybind11 2.5.x with Python 3.9, which is used in
pikepdf 1.x.)
- On some systems, unpaper seems to be unable to process the PNGs we offer it
as input. We now convert the input to PNM format, which unpaper always accepts.
Fixes #665 and #667.
