# Release notes > **Release date: February 25, 2026** ## v2.0.0 - preview **Release date: February 25, 2026** ### ExtractionResultHandler class We have added a ne public class `ExtractionResultHandler` that provides a fluent API for navigating and manipulating extraction results. It acts as an entry point for working with: * Basic fields, * Field groups, * Tables, * Table rows, * Generic (wildcard) data points. `ExtractionResultHandler` wraps an `ExtractionResult` and exposes helper methods to convert raw `ResultsDataPoint` and `ResultsValue` objects into strongly-typed facade classes. This allows easier navigation and manipulation of extraction results without manually casting types. Check out [ExtractionResultsHandler](https://docs.uipath.com/activities/other/latest/document-understanding/extractionresulthandler-class) for more information. ### FieldGroup and MonetaryQuantity support The `FieldType Enum` class now supports `FieldGroup` and `MonetaryQuantity` fields. ## v1.31.0 **Release date: October 28, 2025** ### What's new The `ValidatorNotes` and `ValidatorNotesInfo` properties are now available for all values, including table cells. ## v1.29.4 **Release date: April 16, 2025** ### What's new We have introduced a new `ContentValidationData` class to handle document validation data. This class has been designed specifically for use along with web apps to streamline user validations in Action Center. Using the `ContentValidationData` class, you can configure and retrieve details about the document sent for review in Action Center. For more information on the `ContentValidationData` class and its corresponding properties, visit [ContentValidationData Class](https://docs.uipath.com/activities/other/latest/document-understanding/contentvalidationdata-class "ContentValidationData is a public class that allows you to retrieve and configure details about a document that you want to display in a Validation Control within an App project."). ### Erratum, added April 27, 2026 The `TextType` enumeration was also updated in this release with three new values: `Circle`, `Cut`, and `Underline`. For the full list of supported text types, see [TextType Enum](https://docs.uipath.com/activities/other/latest/document-understanding/229-texttype-enum). ## v1.27.1 **Release date: October 3, 2024** We are constantly working to improve your UiPath Document Understanding experience. Even though there are no significant changes this release, we made minor improvements to the product. ## v1.26.0 **Release date: 29 April 2024** These release notes contain all the updates made between November 2023 and March 2024. ### New Feature & Improvements Two new methods are available for the [ExtractionResult Class](https://docs.uipath.com/activities/other/latest/document-understanding/extraction-result-class "ExtractionResult is a public class that represents an extraction result for a part of a document."). These new features help you access validator notes easier. ## v1.23.1 **Release date: 24 October 2023** ### New Features & Improvements A new property, **Rotation**, has been added to the **Page** object. ## v1.21.1 **Release date: 2 May 2023** ### Bug Fixes We fixed a bug causing the Data Extraction Scope activity to crash when the extraction is completed on all but the first sub-document. This was happening when a classifier was used to perform document splitting and multiple classification results were returned from Classify Document Scope. ## v1.21.0 **Release date: 26 April 2023** ### New features & Improvements * The **ResultsValue** Class received a new property, **TextType** that can provide the text origin of the extracted value. * We've added new overload for the **.Serialize** method that accepts a **SerializationSettings** object. You can now configure whether serialization will be done using a Pascal- or camelCase convention. The default is PascalCase. This applies to the following classes: **Document**, **DocumentTaxonomy**, **DocumentSplittingResult**, **ClassificationResult,** and **ExtractionResult**. You can still use all the existing methods in **PascalCase** and everything is backwards compatible. You can use deserialization with either **Pascal-** or **camelCase** serialized objects. * New classes have been added to the **UiPath.DocumentProcessing.Contracts** package that contains information about the Actions created in Action Center. * A new helper method, **IsTextTypeInDocument,** is available for detecting the presence of a type of text (handwritten or checkboxes) in a document by using a **TextType** parameter. ### Bug Fixes We've fixed a bug causing the **TextType** property to be displayed in both **Values** and **Tokens** sections. The property is now displayed only in the **Values** section. ### Deprecation Timeline We recommend that you regularly check the [deprecation timeline](https://docs.uipath.com/overview/other/latest/overview/deprecation-timeline#activities-upcoming-removals) for any updates regarding features that will be deprecated and removed. ## v1.18.0 **Release date: 13 December 2022** ### New features & Improvements * The **TextType** enumeration has been enriched with the following new classification fields: Barcode, QRcode, Stamp, Logo, and Unknown. * The Studio user interface is now available in Traditional Chinese. ## v1.17.1 **Release date: 24 October 2022** ### New features & Improvements * We have re-factored the Data Extraction Results class to enable its usage within the workflow. We've implemented a new table structure and table helper methods and, for the moment, both old and new structures are available. The new format is supported in Validation Station and other components (trainers, extractors etc.), and going forward it is the recommended way of accessing and manipulating table data in the results object. * Every word from Document Object Model can now be set as type **Text**, **Handwriting**, or **Checkbox**. * The **ResultsValue.Components** property, the **ResultsValue** constructors which have **ResultsDataPoint[]** components as parameters, the **ResultsValue.CreateTableValue** methods, and the **ExtractionResult.FlattenFields** method are now marked as obsolete. * There is a new **ProcessingSource** value, named **PdfAndOcr**, that reflects a PDF page which was processed with both native PDF processing and OCR processing. ## v1.14.0 **Release Date: 9 May 2022** ### New Features and Improvements * The **UiPath.DocumentProcessing.Contracts** package has been upgraded to .NET5 portable, allowing you to run them on Linux robots. * Some of the classes included in the **UiPath.DocumentProcessing.Contracts** package have been updated. Among the updated ones are the Simplified Value, Results Value, and Extraction Result classes. ## v1.11.0 **Release Date: 1 October 2021** ### New Features and Improvements * The **ClassificationResult** class has received new methods, **Serialize** and **Deserialize**, meant to help you serialize and deserialize the classification output. * New methods, **FlattenFields** and **GetFields**, have also been added to the **ExtractionResult** class meant to help you filter the fields based on the given condition. * The **UiPath.DocumentProcessing.Contracts** package has been upgraded to .NET5. While both .NET versions continue to be supported, the .NET5 projects can only work on 64-bit architectures. ### Bug Fixes Fixed an issue related to **Validation Station** that was causing unexpected number formatting when reading the derived parts value. ## v1.10.1 **Release Date: 23 March 2021** ### Improvements Added the `ExtractionResult.AsDataSet(bool includeConfidence, bool includeOcrConfidence)` method that can be used to export an `ExtractionResult` to a `DataSet` while optionally including the **OCR Confidence** of the values. ### Bug Fixes * Fixed an issue with missing API documentation. * Fixed backwards compatibility with **UiPath.IntelligentOCR.Activities** versions lower than 4.11.0. ## v1.9.1 **Release Date: 10 November 2020** ### Bug Fixes Public types exported by the `DocumentProcessing.Contracts` assembly are now XML serializable. ## v1.9.0 **Release Date: 2 October 2020** ### New Features and Improvements * Value extraction null (empty) is allowed in the following scenarios: + Data extraction fields with no reference; + Document classifications with no reference; + Values created by the used in **Validation Station** with no reference. * Added support for custom extractor payload in `ExtractionResults`. * Added support for field-level metadata in Taxonomy. ## v1.6.1 **Release Date: 4 May 2020** ### New Features and Improvements * A new property named `VisualLineNumber` has been added to the public class **Word** indicating on which visual line is the word placed. This can be found under the **UiPath.DocumentProcessing.Contracts.Dom** namespace. * A new extension method named `GetVisualTextProjection` has been added to the **Document** class, allowing you to access a visual arrangement of the words. This can be found under the **UiPath.DocumentProcessing.Contracts.Dom** namespace. ## v1.4.0 **Release Date: 6 November 2019** ### New Features and Improvements A new property is available in the **UiPath.DocumentProcessing.Contracts** pack under the name of **OperatorConfirmed**. This comes as a support for the newly improved Validation Station wizard. ## v1.3.0 **Release Date: 23 September 2019** ### New Features and Improvements * This release brings a new feature for the **UiPath.DocumentProcessing.Contracts** pack. * The public class **Word** received an addition to the word horizontal boxes and now supports polygon information at word level. ## v1.2.0 **Release Date: 19 June 2019** ### New Features and Improvements New public interfaces and abstract classes are now available, for the **UiPath.DocumentProcessing.Contracts.Training** pack. With these new additions you can use the exact needed interface or abstract class for the extractors and classifiers activities. ## v1.1.0 **Release Date: 21 May 2019** ### New Features and Improvements New static methods are available in the `UiPath.DocumentProcessing.Contracts` assembly, which generate `ResultsDerivedField[]` collections. These collections can derive multiple fields from existing results, enabling their usage in the `ResultsValue()` constructor. ## v1.0.0 **Release Date: 22 April 2019** ### New Features and Improvements Our first iteration of the **Document Processing Contracts** package enables you to integrate your own data extraction and classifier activities with the **IntelligentOCR** activities. This means that you can easily integrate your own document processing algorithms into the UiPath® infrastructure, by performing the following actions: * Reference the contracts provided in this package. * Implement your own classifiers and extractors into your workflows.
