Version 2.1.0, 2022-06-06
The highlight of the 2.1.0 release is the most massive improvement to the text extraction capabilities of PyPDF2 since 2016 🥳🎊 A very big thank you goes to pubpub-zz who took a lot of time and knowledge about the PDF format to finally get those improvements into PyPDF2. Thank you 🤗💚
In case the new function causes any issues, you can use _extract_text_old
for the old functionality. Please also open a bug ticket in that case.
There were several people who have attempted to bring similar improvements to PyPDF2. All of those were valuable. The main reason why they didn’t get merged is the big amount of open PRs / issues. pubpub-zz was the most comprehensive PR which also incorporated the latest changes of PyPDF2 2.0.0.
Thank you to VictorCarlquist for #858 and asabramo for #464 🤗

Version 2.0.0, 2022-06-01
The 2.0.0 release of PyPDF2 includes three core changes:
Dropping support for Python 3.5 and older.
Introducing type annotations.
Interface changes, mostly to have PEP8-compliant names
We introduced a deprecation process that hopefully helps users to avoid unexpected breaking changes.
Breaking Changes (DEP)
PyPDF2 2.0 requires Python 3.6+. Python 2.7 and 3.5 support were dropped.
PdfFileReader: The “warndest” parameter was removed
PdfFileReader and PdfFileMerger no longer have the
overwriteWarnings
parameter. The new behavior isoverwriteWarnings=False
.merger: OutlinesObject was removed without replacement.
merger.py ➔ _merger.py: You must import PdfFileMerger from PyPDF2 directly.
