Version 4.0.0, 2024-01-19

What's new

pypdf==4.0.0 is a big milestone forward:

• We finally have a layout-mode text extraction. This enables users who want to detect / extract tables with heuristics to give it a try.
• We deprecated a lot of the old PyPDF2 API that was either not following PEP8 naming styles or was not using a property. Users coming from PyPDF2 might want to switch to pypdf<4.0.0 first to get helpful error messages that show the new API in their specific cases.

A big 'Thank you!' the the whole pypdf community for your work. Thanks to you, pypdf is better than ever.

Kudos to @shartzog who added the layout-mode with his first contribution!
