Full Changelog: 0.4.0...0.4.1

0.4.0

What's Changed

• Expand PyMuPDF4LLM configuration options by @lakinduboteju in #7

The pymupdf4llm_kwargs parameter in the PyMuPDF4LLMLoader allows you to pass additional keyword arguments directly to the underlying pymupdf4llm.to_markdown function, which is used internally by the PyMuPDF4LLMParser.

This provides flexibility to customize the PDF parsing and markdown conversion process using options available in the pymupdf4llm library that are not explicitly exposed as parameters in the PyMuPDF4LLMLoader itself.

Support for latest pymupdf4llm version 0.0.22.
