Changelog

Sourced from unstructured[all-docs]'s changelog.

0.22.18

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.

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

Fixes

• Fix fast strategy silently skipping text in some PDFs: Certain PDF generators (e.g. Prince XML) embed font encoding data in a non-standard way that pdfminer.six does not handle, causing body text to be silently dropped while headings still extract correctly. Added a workaround that reads the embedded encoding data directly.

0.22.11

Enhancements

• Exclude unused spaCy components: Exclude ner, lemmatizer, and attribute_ruler when loading en_core_web_sm, keeping parser for accurate sentence boundaries. Saves ~7 MiB peak memory.

0.22.10

Enhancements

• Repeat table headers across continuation chunks: Add repeat_table_headers to basic/title chunking options and table chunking internals so leading header rows are detected once and carried forward when large tables spill across multiple chunks.

0.22.9

Enhancements

• Isolate Table elements during chunking: Table and TableChunk elements are always placed in their own pre-chunk and are never merged with adjacent text into a CompositeElement, nor combined with neighboring pre-chunks when combine_text_under_n_chars is enabled. Shared helpers in unstructured.chunking.base centralize the table-isolation checks. Inter-chunk overlap (overlap + overlap_all) no longer carries narrative text into table pre-chunks or table tails into following text chunks.
