0.15.5

0.15.5

Enhancements

Features

Fixes

• Revert to using unstructured.pytesseract fork. Due to the unavailability of some recent release versions of pytesseract on PyPI, the project now uses the unstructured.pytesseract fork to ensure stability and continued support.
• Bump libreoffice verson in image. Bumps the libreoffice version to 25.2.5.2 to address CVEs.
• Downgrade NLTK dependency version for compatibility. Due to the unavailability of nltk==3.8.2 on PyPI, the NLTK dependency has been downgraded to <3.8.2. This change ensures continued functionality and compatibility.

Features

Fixes

• Remove the custom index URL from extra-paddleocr.in to resolve the error in the setup.py configuration.

0.15.2

0.15.2

Enhancements

• Improve directory handling when extracting image blocks. The figures directory is no longer created when the extract_image_block_to_payload parameter is set to True.

Features

• Added per-class Object Detection metrics in the evaluation. The metrics include average precision, precision, recall, and f1-score for each class in the dataset.

Fixes

• Updates NLTK data file for compatibility with nltk>=3.8.2. The NLTK data file now container punkt_tab, making it possible to upgrade to nltk>=3.8.2. The nltk==3.8.2 patches CVE-2024-39705.
• Renames Astra to Astra DB Conforms with DataStax internal naming conventions.
• Accommodate single-column CSV files. Resolves a limitation of partition_csv() where delimiter detection would fail on a single-column CSV file (which naturally has no delimeters).
• Accommodate image/jpg in PPTX as alias for image/jpeg. Resolves problem partitioning PPTX files having an invalid image/jpg (should be image/jpeg) MIME-type in the [Content_Types].xml member of the PPTX Zip archive.
• Fixes an issue in Object Detection metrics The issue was in preprocessing/validating the ground truth and predicted data for object detection metrics.
• Removes dependency on unstructured.pytesseract Unstructured forked pytesseract while waiting for code to be upstreamed. Now that the new version has been released, this fork can be removed.

0.15.1

0.15.1

Enhancements

• Improve pdfminer embedded image extraction to exclude text elements and produce more accurate bounding boxes. This results in cleaner, more precise element extraction in pdf partitioning.

Features

• Update partition_eml and partition_msg to capture cc, bcc, and message_id fields Cc, bcc, and message_id information is captured in element metadata for both msg and email partitioning and Recipient elements are generated for cc and bcc when include_headers=True for email partitioning.
• Mark ingest as deprecated Begin sunset of ingest code in this repo as it's been moved to a dedicated repo.
• Add pdf_hi_res_max_pages argument for partitioning, which allows rejecting PDF files that exceed this page number limit, when the high_res strategy is chosen. By default, it will allow parsing PDF files with an unlimited number of pages.

Fixes

• Update HuggingFaceEmbeddingEncoder to use HuggingFaceEmbeddings from langchain_huggingface package instead of the deprecated version from langchain-community. This resolves the deprecation warning and ensures compatibility with future versions of langchain.
• Update OpenAIEmbeddingEncoder to use OpenAIEmbeddings from langchain-openai package instead of the deprecated version from langchain-community. This resolves the deprecation warning and ensures compatibility with future versions of langchain.
• Update import of Pinecone exception Adds compatibility for pinecone-client>=5.0.0
• File-type detection catches non-existent file-path. detect_filetype() no longer silently falls back to detecting a file-type based on the extension when no file exists at the path provided. Instead FileNotFoundError is raised. This provides consistent user notification of a mis-typed path rather than an unpredictable exception from a file-type specific partitioner when the file cannot be opened.
• EML files specified as a file-path are detected correctly. Resolved a bug where an EML file submitted to partition() as a file-path was identified as TXT and partitioned using partition_text(). EML files specified by path are now identified and processed correctly, including processing any attachments.
• A DOCX, PPTX, or XLSX file specified by path and ambiguously identified as MIME-type "application/octet-stream" is identified correctly. Resolves a shortcoming where a file specified by path immediately fell back to filename-extension based identification when misidentified as "application/octet-stream", either by asserted content type or a mis-guess by libmagic. An MS Office file misidentified in this way is now correctly identified regardless of its filename and whether it is specified by path or file-like object.
• Textual content retrieved from a URL with gzip transport compression now partitions correctly. Resolves a bug where a textual file-type (such as Markdown) retrieved by passing a URL to partition() would raise when gzip compression was used for transport by the server.
• A DOCX, PPTX, or XLSX content-type asserted on partition is confirmed or fixed. Resolves a bug where calling partition() with a swapped MS-Office content_type would cause the file-type to be misidentified. A DOCX, PPTX, or XLSX MIME-type received by partition() is now checked for accuracy and corrected if the file is for a different MS-Office 2007+ type.
• DOC, PPT, XLS, and MSG files are now auto-detected correctly. Resolves a bug where DOC, PPT, and XLS files were auto-detected as MSG files under certain circumstances.

0.15.0

0.15.0

Enhancements

• Improve text clearing process in email partitioning. Updated the email partitioner to remove both =\n and =\r\n characters during the clearing process. Previously, only =\n characters were removed.
• Bump unstructured.paddleocr to 2.8.0.1.
• Refine HTML parser to accommodate block element nested in phrasing. HTML parser no longer raises on a block element (e.g. <p>, <div>) nested inside a phrasing element (e.g. <strong> or <cite>). Instead it breaks the phrasing run (and therefore element) at the block-item start and begins a new phrasing run after the block-item. This is consistent with how the browser determines element boundaries in this situation.
• Install rewritten HTML parser to fix 12 existing bugs and provide headroom for refinement and growth. A rewritten HTML parser resolves a collection of outstanding bugs with HTML partitioning and provides a firm foundation for further elaborating that important partitioner.
• CI check for dependency licenses Adds a CI check to ensure dependencies are appropriately licensed.

Features

• Add support for specifying OCR language to partition_pdf(). Extend language specification capability to PaddleOCR in addition to TesseractOCR. Users can now specify OCR languages for both OCR engines when using partition_pdf().
• Add AstraDB source connector Adds support for ingesting documents from AstraDB.

Fixes

• Remedy error on Windows when nltk binaries are downloaded. Work around a quirk in the Windows implementation of tempfile.NamedTemporaryFile where accessing the temporary file by name raises PermissionError.
• Move Astra embedded_dimension to write config

0.14.10

0.14.10

Enhancements

• Update unstructured-client dependency Change unstructured-client dependency pin back to
  greater than min version and updated tests that were failing given the update.
• .doc files are now supported in the arm64 image.. libreoffice24 is added to the arm64 image, meaning .doc files are now supported. We have follow on work planned to investigate adding .ppt support for arm64 as well.
• Add table detection metrics: recall, precision and f1
• Remove unused _with_spans metrics

Features

Fixes

• Fix counting false negatives and false positives in table structure evaluation
• Fix Slack CI test Change channel that Slack test is pointing to because previous test bot expired
• Remove NLTK download Removes nltk.download in favor of downloading from an S3 bucket we host to mitigate CVE-2024-39705

0.14.9

0.14.9

Enhancements

• Added visualization and OD model result dump for PDF In PDF hi_res strategy the analysis parameter can be used to visualize the result of the OD model and dump the result to a file. Additionally, the visualization of bounding boxes of each layout source is rendered and saved for each page.
• partition_docx() distinguishes "file not found" from "not a ZIP archive" error. partition_docx() now provides different error messages for "file not found" and "file is not a ZIP archive (and therefore not a DOCX file)". This aids diagnosis since these two conditions generally point in different directions as to the cause and fix.

Features

Fixes

• Fix a bug where multiple soffice processes could be attempted Add a wait mechanism in convert_office_doc so that the function first checks if another soffice is running already: if yes wait till the other process finishes or till the wait timeout before spawning a subprocess to run soffice
• partition() now forwards strategy arg to partition_docx(), partition_pptx(), and their brokering partitioners for DOC, ODT, and PPT formats. A strategy argument passed to partition() (or the default value "auto" assigned by partition()) is now forwarded to partition_docx(), partition_pptx(), and their brokering partitioners when those filetypes are detected.

0.14.8

0.14.8

Enhancements

• Move arm64 image to wolfi-base The arm64 image now runs on wolfi-base. The arm64 build for wolfi-base does not yet include libreoffce, and so arm64 does not currently support processing .doc, .ppt, or .xls file. If you need to process those files on arm64, use the legacy rockylinux image.

Features

Fixes

• Bump unstructured-inference==0.7.36 Fix ValueError when converting cells to html.

• partition() now forwards strategy arg to partition_docx(), partition_ppt(), and partition_pptx(). A strategy argument passed to partition() (or the default value "auto" assigned by partition()) is now forwarded to partition_docx(), partition_ppt(), and partition_pptx() when those filetypes are detected.

• Fix missing sensitive field markers for embedders

0.14.7

0.14.7

Enhancements

• Pull from wolfi-base image. The amd64 image now pulls from the unstructured wolfi-base image to avoid duplication of dependency setup steps.
• Fix windows temp file. Make the creation of a temp file in unstructured/partition/pdf_image/ocr.py windows compatible.

Features

• Expose conversion functions for tables Adds public functions to convert tables from HTML to the Deckerd format and back

Fixes

• Fix an error publishing docker images. Update user in docker-smoke-test to reflect changes made by the amd64 image pull from the "unstructured" "wolfi-base" image.
• **Fix a IndexError when partitioning a pdf with values for both extract_image_block_types and starting_page_number.
