Generating name objects (NameObject) without a leading slash
is considered deprecated now. Previously, just a plain warning
would be logged, leading to possibly invalid PDF files. According

NOTICE: pypdf changed the way it represents numbers parsed from PDF files. pypdf<3.4.0 represented numbers as Decimal, pypdf>=3.4.0 represents them as floats. Several other PDF libraries to this, as well as many PDF viewers. We hope to fix issues with too high precision like this and get a speed boost. In case your PDF documents rely on more than 18 decimals of precision you should check if it still works as expected. To clarify: This does not affect the text shown in PDF documents. It affects numbers, e.g. when graphics are drawn on the PDF or very exact positions are used. Typically, 5 decimals should be enough.

Move PyPDF2 to pypdf (#1513). This now it's all lowercase, no number in the name. For installation and for import. PyPDF2 will no longer receive updates. The community should move back to its roots.
If you were still using pyPdf or PyPDF2 < 2.0.0, I recommend reading the migration guide: https://pypdf.readthedocs.io/en/latest/user/migration-1-to-2.html
pypdf==3.1.0 is only different from PyPDF2==3.0.0 in the package name.
Replacing "PyPDF2" by "pypdf" should be enough if you migrate from
PyPDF2==3.0.0 to pypdf==3.1.0.

- Extraction of CMaps improved
- Fallback for font def missing
- Support for /Identity-H and /Identity-V: utf-16-be

Those changes should mainly improve the text extraction for non-ASCII alphabets, e.g. Russian / Chinese / Japanese / Korean / Arabic.

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 🤗

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.
- 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
overwriteWarningsparameter. The new behavior isoverwriteWarnings=False. - merger: OutlinesObject was removed without replacement.
- merger.py ➔ _merger.py: You must import PdfFileMerger from PyPDF2 directly.
- utils:
ConvertFunctionsToVirtualListwas removedformatWarningwas removedisInt(obj): Useinstance(obj, int)insteadu_(s): Usesdirectlychr_(c): Usechr(c)insteadbarray(b): Usebytearray(b)insteadisBytes(b): Useinstance(b, type(bytes()))insteadxrange_fn: Userangeinsteadstring_type: UsestrinsteadisString(s): Useinstance(s, str)instead_basestring: Usestrinstead- All Exceptions are now in
PyPDF2.errors:- PageSizeNotDefinedError
- PdfReadError
- PdfReadWarning
- PyPdfError
PyPDF2.pdf(thepdfmodule) no longer exists. The contents were moved with the library. You should most likely import directly fromPyPDF2instead. TheRectangleObjectis inPyPDF2.generic.- The
Resources,Scripts, andTestswill no longer be part of the distribution files on PyPI. This should have little to no impact on most people. TheTestsare renamed totests, theResourcesare renamed toresources. Both are still in the git repository. TheScriptsare now in cpdf.Sample_Codewas moved to thedocs.
For a full list of deprecated functions, please see the changelog of version 1.28.0.
