0.22.21

What's Changed

• feat: add option to skip table chunking by @​badGarnet in Unstructured-IO/unstructured#4338

Full Changelog: Unstructured-IO/unstructured@0.22.20...0.22.21

0.22.20

What's Changed

• Fix fixtures update CI to regenerate markdown by @​vladimir-kivi-ds in Unstructured-IO/unstructured#4332
• fix(deps): upgrade vulnerable transitive dependencies [security] by @​utic-github-cicd-token-generator[bot] in Unstructured-IO/unstructured#4334
• feat: add GHA workflow to build opencv wheels without ffmpeg by @​lawrence-u10d in Unstructured-IO/unstructured#4335
• Enable vertical text detection for rotated images by @​vladimir-kivi-ds in Unstructured-IO/unstructured#4328

New Contributors

• @​utic-github-cicd-token-generator[bot] made their first contribution in Unstructured-IO/unstructured#4334

Full Changelog: Unstructured-IO/unstructured@0.22.18...0.22.20

0.22.18

What's Changed

• fix(chunking): preserve semantic headers in carried table chunks by @​cragwolfe in Unstructured-IO/unstructured#4313
• feat: add page number support to v1 html partition by @​badGarnet in Unstructured-IO/unstructured#4327

Full Changelog: Unstructured-IO/unstructured@0.22.16...0.22.18

0.22.16

Enhancements

• Formula markdown export (element_to_md / elements_to_md): New keyword-only formula_markdown_style ("auto", "display_math", "plain"; default "auto"). In "auto", display math ($$ ... $$) is used only when the text looks like notation (heuristic score) and contains no $/$$ (avoids breaking Markdown and noisy OCR captions). "display_math" wraps whenever safe (still falls back to plain if $ would corrupt fences). "plain" emits text only. Optional normalize_formula (default True) maps common Unicode operators to LaTeX-like tokens; normalize_formula stays before keyword-only options so positional encoding / no_group_by_page callers are unchanged. Unicode √ is never mapped to \\sqrt{}. Module constants: FORMULA_MARKDOWN_AUTO, FORMULA_MARKDOWN_DISPLAY_MATH, FORMULA_MARKDOWN_PLAIN.

0.22.15

Security

• security: fix(deps): upgrade vulnerable transitive dependencies [security]

0.22.14

Enhancements

• Deduplicate PDF rendering: Remove _render_pdf_pages and delegate to unstructured-inference's convert_pdf_to_image (which already has lazy per-page rendering). Peak memory for path_only=True drops from O(n_pages) to O(1 page) — 97% reduction on a 100-page PDF. Bumps inference dep to >=1.6.2.

0.22.13

Enhancements

• Speed up standardize_quotes: Replace loop-based character replacement with a single str.translate() call using a pre-computed translation table. Also fixes a pre-existing bug where left smart quotes were never normalized due to duplicate dictionary keys.

0.22.12

Changelog

Sourced from unstructured's changelog.

0.22.21

Enhancements

• Skip table chunking option: Add skip_table_chunking to basic/title chunking options. When True, Table elements are passed through unchanged without being split into TableChunk elements, regardless of their size. Defaults to False to preserve existing behavior.

0.22.20

Enhancements

• Auto-detect vertical text for rotated PDFs: Add detect_vertical field to PDFMinerConfig and auto-enable it when rendered pages have /Rotate metadata, so pdfminer groups rotated text into proper words instead of per-character regions

0.22.19

Security

• security: fix(deps): upgrade vulnerable transitive dependencies [security]

0.22.18

Fixes

• Make ingest-test-fixtures-update-pr CI job also update the markdown versions of the fixtures.

Enhancements

• Add page number support to v1 HTML parser: The v1 HTML parser now reads data-page-number attributes from ancestor elements and includes the page number in element metadata, consistent with the v2 parser behavior.

0.22.17

Fixes

• Preserve semantic table headers across carried chunks: Carried rows in split table chunks now keep original header semantics (th stays th, including section header rows and wrapped header text), preventing header cells from degrading to data cells in continuation chunks.

0.22.16

Enhancements

• Formula markdown export (element_to_md / elements_to_md): New keyword-only formula_markdown_style ("auto", "display_math", "plain"; default "auto"). In "auto", display math ($$ ... $$) is used only when the text looks like notation (heuristic score) and contains no $/$$ (avoids breaking Markdown and noisy OCR captions). "display_math" wraps whenever safe (still falls back to plain if $ would corrupt fences). "plain" emits text only. Optional normalize_formula (default True) maps common Unicode operators to LaTeX-like tokens; normalize_formula stays before keyword-only options so positional encoding / no_group_by_page callers are unchanged. Unicode √ is never mapped to \\sqrt{}. Module constants: FORMULA_MARKDOWN_AUTO, FORMULA_MARKDOWN_DISPLAY_MATH, FORMULA_MARKDOWN_PLAIN.
