UiPath Release Notes



Release Date: 8th November 2019

New Features and Improvements

New exciting features and improvements are brought to you with this release.

A new activity meant to help you better organize and manage your trainable classifiers is available: Keyword Based Classifier Trainer. This activity can be used only together with the Train Classifiers Scope activity.

The Validation Station wizard received an important upgrade and is now available for you to explore its maximum potential. This wizard becomes available only when the Present Validation Station activity is used in a workflow. You can use the upgraded version for benefiting from a new user-friendly interface, navigating through the document while using the keyboard shortcuts or selecting one or multiple words or a custom area. You can easily mark a field as missing, extract new data, edit a table or extract a new table. All these marvelous things can be done with the Validation Station wizard while using a dark theme.

One of the improvements included in this release is that the Keyword Based Classifier activity received a new parameter named LearningData. Besides specifying where the learning file data are located, you can now also use the string containing the serialized classifier data. This activity was enhanced with a wizard named Manage Keyword Based Classifier Learning that can be used for configuring and managing the keywords used for identifying specific document types.

Both the Keyword Based Classifier and Keyword Based Classifier Trainer activities are now able to manage multiple keywords. After the keyword sets are selected, the extraction is based on a full match of the selected words.

Another great improvement is that the DocumentObjectModel output, included in the Digitize Document activity, can now support word polygons, besides word horizontal boxes.

The Taxonomy Manager wizard received a new scrolling bar that incorporates all UI elements and it provides a better user experience.

Data Extraction Scope, Train Extractors Scope, Train Classifier Scope and Classify Document Scope activities are now arranging their extractors and classifiers in a horizontal order, replacing the previous vertical order.

The Regex Based Extractor activity has been improved and can now process and return multi-values. The output is visible only when the activity is used together with the Validation Station.

Four new languages, Turkish (TR), Portuguese (PT), Spanish (ES), and Spanish-Mexico (ES-MX) are available for the UiPath.IntelligentOCR.Activities package.

Known Issues

  • Taxonomy Manager can be accessed only if you previously opened a .xaml file. If no files are opened when you access the Taxonomy Manager, a recording window is shown and Taxonomy Manager is displayed only after closing the recording window.

Bug Fixes

  • An exception was thrown when using the Data Extraction Scope activity together with a Try Catch activity. The issue was fixed and now the activity is executed as expected.
  • When a Boolean field was set to No in Validation Station, the output file should have shown the result as No but instead is showing it as missing. The issue was fixed and now the output file shows the correct result.
  • Fixed incorrect number parsing that occurred when the Data Extraction Scope was trying to parse numbers in documents using a different number format than the document's culture.
  • When using multiple Validation Stations, the order of the derived parts was not respected in the validated results. The issue was fixed and now the results are displaying the derived parts in the same order they were introduced.
  • Differences between the boxes with custom selection occurred when the results of a Validation Station were run through a second Validation Station. The issue was fixed and now there are no differences between boxes with custom selection.
  • When the Digitize Document activity was used together with Microsoft Azure Computer Vision OCR engine, the rotation was not working when HandwritingRecognition parameter was set as True. The issue was fixed and now the information is processed correctly.
  • When using Digitize Document activity, an error occurred when trying to process images with a lot of text. The bug was fixed by improving the scaling process.
  • Fixed an issue that was throwing when trying to train the Keyword Based Classifier activity in the training scope and the extraction was run without a classification reference. The issue was fixed and now the fact that there is no learning information is only logged, not thrown as an error.
  • An error was thrown when using the [FlexiCapture Extractor]https://docs.uipath.com/activities/docs/flexicapture-extractor) activity and the same name was given to both a table column and a field. The issue was fixed and the .fcdot file is now processed as expected.


If an error mentioning the Docotic.Pdf library is encountered at runtime, then you should upgrade the UiPath.IntelligentOCR.Activities package to version v3.1.0 or higher.


Release Date: 26th August 2019

New Features and Improvements

This release presents a new activity, RegEx Based Extractor accompanied by a wizard as well. You are now able to easily configure your RegEx expression by using the wizard and to extract specific information from documents.

Three new languages, German (DE), South Korean (KO), and Portuguese (PT-BR) are available for the UiPath.IntelligentOCR.Activities package.

Breaking Changes

  • Major updates related to the internal handling of .pdf files occurred for the Digitize Document activity. This has led to a breaking change for the UiPath.IntelligentOCR activities pack, which caused the version to skip ahead from v2.3.0 to v3.0.0.

Bug Fixes

  • Fixed an issue which caused the Digitize Document activity to throw an error when trying to process a high-resolution image inside a .pdf file. Now, the high-resolution images are processed correctly and digitized.
  • Fixed an issue which caused the Present Validation Station activity to fail loading images with very high resolutions. Now all images, no matter of the resolution size, are processed correctly.
  • Fixed an issue which caused the Digitize Document activity to receive incorrect character coordinates. The character coordinates are now received correctly.
  • Improved integration of the Digitize Document activity with OCR engines, including support for rotation (where supported by the OCR engine) and improved accuracy of word-building.


If you want to use the UiPath.IntelligentOCR.Activities package in the same project with the UiPath.PDF.Activities package, you need to use either version 2.x of both, or versions 3.x of both.
UiPath.IntelligentOCR.Activities version 3.0 and higher is incompatible with a UiPath.PDF.Activities version lower than 3.0, and a UiPath.PDF.Activities version 3.0 or higher is incompatible with an UiPath.IntelligentOCR.Activities version lower than 3.0.

New Features and Improvements

As you're probably used to by now, month after month we draw closer to our final goal of creating the ultimate document processing platform. Alongside the first enterprise release of this year, the IntelligentOCR activities pack has been imbued with some new activities, as follows:

The UiPath.DocumentProcessing.Contracts pack enables you to implement your own extractor and classifier activities by simply referencing it. This assembly contains all the classification and extraction interfaces that underlie the IntelligentOCR activities.

The Taxonomy Manager now displays the Document Type ID of the document type that is being edited.

Breaking Changes

While migrating to the public UiPath.DocumentProcessing.Contracts, the IntelligentOCR v2.0.0 activity pack introduces breaking changes for the Classify Document Scope and Train Classifiers And Extractors activities.

Release Date: 20th February 2019

New Features and Improvements

The Taxonomy Manager is the next piece of the document processing puzzle, a wizard created to help you build custom taxonomy files which can then be reused across processes.

We have developed the Load Taxonomy activity, which grants you the ability to load a taxonomy created with the aid of the Taxonomy Manager wizard into a variable which can then be passed on to other activities.

The DegreeOfParallelism property has been added to the Digitize Document activity, enabling you to perform OCR analysis on multiple pages simultaneously. This is not a breaking change, so old workflows still function properly after updating to the latest version of the pack.

The IntelligentOCR pack is now upgraded to .NET Framework v4.6.1.

The MatchingDocumentDefinition property of the FCDocument variable has been exposed. Assigning it to a variable generates the same result as a Classify Document activity.
