PyPDF2 v2.1.0 Release Notes

Release Date: 2022-06-06 // about 2 years ago

  • 🚀 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 🤗
