Release notes

v24.10.7

Release Date: December 5, 2024

Bug fixes

Several System activities incorrectly logged the "[AutomationTracker]: The service is not enabled" message.

Security fixes

This release brings several minor improvements and security fixes.

v24.10.6

Release Date: October 21, 2024

What's new

This package version brings in a new activity, currently in preview, aimed to help you execute business rules defined in Orchestrator. The Evaluate Business Rule activity not only streamlines decision-making processes in your workflows, but also enhances auditing of complex decisions, and assesses their impact as part of an end-to-end process.

Improvements

• System activities for storage bucket operations now support the disabled pre-signed URL setting. This prevents the use of pre-signed URLs during storage bucket operations.

• To update the JSON schema properties of the selected queue in an Add Queue Item activity, use the Refresh arguments option next to the Item Information property.

• A new property, Timeout (ms), has been added to Is Text Matching, Find Matching Patterns, and Replace Matching Patterns activities. It helps prevent performance issues when these activities process complex or inefficient RegEx patterns.

• Minor UI tweaks for several activities include changing the Import Arguments and Open Workflow buttons into clickable links: Refresh arguments and Open workflow. The Open workflow change applies to the Invoke Workflow File activity while the Refresh arguments link is relevant for Invoke Workflow File, Invoke Process, and Add queue item activities. To open the arguments list and edit their attributes, select the Arguments field box.

  

• The Browse for file activity allows you to set a default directory that automatically opens in the Open dialog box. It also allows multiple files to be selected at once and outputs a list that contains the full paths to those files.

Bug fixes

• Outputs from Input Dialog and Browse For Folder activities contained unexpected characters, due to an encoding issue.

• Special characters in file names would prevent the successful execution of the Delete Storage File activity.

• Tooltips for the Username and Password fields in the Get Credential activity were previously interchanged. Now, they are displayed correctly.

• Prompts from Browse for File and Browse for Folder activities weren’t always displayed on top of other applications.

Security fixes

• This release brings several minor improvements and security fixes.

v24.10.5

Release Date: September 9, 2024

Bug fixes

• Previously, the Invoke Workflow activity displayed multiple output arguments on the same, single line. Now, each output argument is displayed on a separate line.

• We've addressed several vulnerabilities.

v24.10.4

Release Date: July 15, 2024

Starting with this package version, System activities need Studio 2023.4 or newer.

Erratum

Important:

Versions 24.10.3, 24.10.2, 24.10.1, and 24.10.0 are unavailable for selection in the Official feed of activity packages. Use the latest package version for System activities, 24.10.4.

v24.10.3

Release Date: July 1, 2024

Bug fixes

The Invoke Workflow File activity would still display a warning for missing arguments, even if they were correctly configured.

v24.10.2

Release Date: June 27, 2024

Bug fixes

In cross-platform projects, the Invoke Workflow File activity encountered an issue when trying to access files from a subfolder, causing it to fail.

v24.10.1

Release Date: June 27, 2024

Bug fixes

An issue prevented coded workflow files from being published or compiled if they were declared in a namespace starting with "UiPath."

v24.10.0

Release Date: June 27, 2024

Improvements

• Files keep their original names when handled via compression and extraction activities. Additionally, new activity properties help you manage how files are zipped or unzipped.

• A new design proposes a logical sequence for For each activities. The values you provide in the In and Current item fields define the activity’s title.

  For example, with "emails" in the In field and "userEmail" in the Current item field, the title becomes "For each userEmail in emails". Modifying the Current item value instantly adjusts the title. If you erase this value, the system auto-generates a default name such as "currentItem". Additionally, the Current item field moves to the Advanced-options section of the activity.

• Transaction-specific properties, including Id, Progress, SpecificContent, Reference, QueueName, and RetryNo, are now available for selection in activities that produce a QueueItem object. However, an exception is the Get Queue Items activity, which doesn't display these properties in Studio Web.

• The log level for the "Transaction video snapshot is not supported" message has been downgraded from Warning to Info .

• In the New Item Added to Queue activity, queues with a Specific Data JSON schema now have a new Specific Data output property, allowing direct access to user-defined queue properties.

• The GetCredential API now provides two functions:

  • string GetCredential (...), where you provide an asset name and the method returns the username.

  • (string, SecureString) GetCredential (...), where you provide an asset name, and the method returns the username and the password.

• A more intuitive configuration experience has been added to the Invoke process activity. Additionally, it now provides automatic context identification of process arguments.

• The Invoke Workflow File activity now offers the same user experience and configuration properties for both Windows and Cross-platform projects. Plus, it introduces several new properties to simplify arguments handling and setting up execution.

Bug fixes

• Transaction operations displayed the warning message "Transaction video snapshot is not supported" to indicate a robot version incompatible with the job recording feature. This occurred even when the transaction was successful.

• An Invalid Operation Exception sometimes occurred when using the Kill Process activity in a library-based project.

• The text preview fails when using new lines in Text Builder widgets of activities managing text or dates. This issue occured as the activity automatically replaced the text for a String.Format() expression, which could not be parsed.

  Note:

  The fix currently applies to System activities used in Studio Web projects.

v24.3.1

Release Date: April 10, 2024

Bug fixes

Wait for Download and Do While activities were incorrectly displaying an extra Body property in Studio Web.

v24.3.0

Release Date: April 1, 2024

Get Transaction Item: New Specific Data output property

In the Get Transaction Item activity, queues with a Specific Data JSON schema now have a new Specific Data output property, allowing direct access to user-defined queue properties.

Invoke Power Shell: New Execution Mode property

When using modules in the Invoke Power Shell activity, you can now directly select a PowerShell version through the Execution Mode property, which displays the following options:

• PowerShell Core 7.2.15

• WindowsPowerShell 5.1 64 bit

• WindowsPowerShell 5.1 32 bit (for Legacy projects)

The following recommendations apply:

• For the VSTeam module, use PowerShell Core 7.2.15, as it does not require deserialization, and the output can be easily used inside the workflow.

• For process argument transformation, use the WindowsPowerShell 5.1 execution mode.

• For the CimCmdlet module, use the WindowsPowerShell 5.1 execution mode.

Improvements

• The Get Credential activity can now retrieve credentials from an offline Credential Store - configured in Orchestrator as a disconnected proxy. This means you can retrieve only Windows credentials without having your passwords travelling through our cloud.

• System activities now support the Retry-after response header for Orchestrator operations.

• The Sample Input field of the Generate Data Table From Text activity has been improved to:

  • support Tab characters

  • use a monospace font

  These improvements simplify data visualization in Legacy and Windows projects.

• For the Add Transaction Item activity, we’ve moved the Transaction Item field to the dedicated section for Output properties.

• We’ve renamed the Output Data Table activity to Output Data Table as Text. Additionally, searching for the term convert returns this activity as a result.

Bug fixes

• In versions 22.10.8+ of UiPath.System.Activities, the Generate Data Table From Text activity may process tables incorrectly when:

  • the input text includes fixed width columns padded with spaces.

  • header column names span across multiple rows.

  This version improves column autodetection and processing.

• We’ve addressed the issue where System activities for credentials and assets lost their configured values when disconnecting from Orchestrator. Additionally, all Orchestrator activities now maintain values that were associated with the selected Orchestrator folder.

• Get Asset and Get Credential activities now work properly with on-premises Orchestrator versions 2023.10 and older.

• Now, when you drag and drop a credential into the Get Asset activity, the Asset Name field is marked with an error, therefore preventing the workflow’s execution.
• Read Text File, Write Text File, and Append Line activities now support shift_jis as an Enconding value.

• The Build Collection activity now supports single-item collections.

• The Raise Alert activity now works as expected when the Continue on error property is set to True.

v23.10.6

Release Date: April 1, 2024

Improvements

V20.4.4

Release Date: 20 October 2020

Improvements

This release addresses the hotfix released by Microsoft for a critical security vulnerability in the way .NET deserializes XML.

V20.10.1

Release Date: 12 October 2020

New Features and Improvements

We have developed a completely new scope activity for triggers, called Trigger Scope. This activity is usable with all the triggers present in both UIAutomation and System activity packs. It offers the required arguments to work with the trigger out of the box, like trigger name and type or its source event. Moreover, it can treat the incoming events sequentially or concurrently while it can exit after one execution.

The Process Start Trigger, Process End Trigger, and Break activities can now be used inside the Trigger Scope activity.

The activity has been made compatible with Studio, which means you can now use its functionality when building workflows with your favorite profile.

The new Modify Text activity enables you to update a text value using modifications including find and replace, trim, and combining (concatenating) with another text value.

The new Text to Left/Right activity enables you to retrieve the text to the left and to the right of a specified separator.

The new Compress/Zip Files activity enables you to add files or folders to a compressed (zip) file.

The new Extract/Unzip Files enables you to extract all the contents of a zip file archive to a specified folder.

The Wait Queue Item activity has migrated away from using the Timeout (milliseconds) property to determine its timeout duration and, instead, uses the Heartbeat interval, so it can sync much more efficiently with Orchestrator.

The Download File activity has been renamed to Wait for Download to better reflect the intended usage of the activity in your automation projects.

This activity pack has now been upgraded and is fully compatible with the C# Studio feature. For more information about C# support, see About Automation Projects.

The amount of packages you can find on UiPath activity feeds is humongous, and it grows with each passing day. This can prove to be a nuisance when searching for a package with a more common name, for example. We felt your pain and decided to do something about this. From now on, all UiPath official activity packs can be easily filtered in the Package Manager so you’ll be able to reach your favorite package in no time!

This release also addresses the hotfix released by Microsoft for a critical security vulnerability in the way .NET deserializes XML.

The HTTP Request activity now enables you to set custom accepted response MIME types (provided through a dedicated header) when you choose the new CUSTOM value in the AcceptFormat property, thus no longer limiting responses to the built-in formats.

Use the new endpoint SetRobotAssetByRobotKey to set the asset value in the Set Asset and Set Credential activities.

Breaking Changes

• The default encoding used by the Append Line activity when a new file is created is now UTF-8 instead of the default operating system encoding. A new property called Use default encoding has been added to the activity. If you want to use the default Windows encoding, you must select this option. By default, the option is not selected.
• The Write Line activity now only outputs logs at Trace level. Any past workflows relying on the fact that the activity used to output logs at Info level might suffer breaking changes.

Known Issues

• Arguments for Invoke Workflow File function as By Referefence if same process, By Value if isolated process.

• Due to internal changes, several activities are no longer visible in the Favorites list when upgrading to v20.4 or newer, if they were added to the Favorites list with a v19.4 or older version of UiPath.System.Activities. The following activities are impacted:

  • Log Message
  • Filter Data Table
  • Message Box
  • File Change Trigger
  • Invoke Code
  • Retry Scope
• If Invoke Method receives an argument variable whose name is a single character, the character itself is used as an argument instead of the contents of the variable.

Bug Fixes

• Fixed an issue that caused the HTTP Request activity to fail if either only username or password was provided in their respective property field in the Simple Authentication section.
• The Multiple Assign activity now works as expected in large workflows. In previous releases, if a large number of variables were added in Multiple Assign, the activity fields displayed incorrect or missing values, and Studio became slow when navigating inside the workflow or updating variables in the Variables panel.
• Fixed an issue that caused an unexpected error to be logged in the Studio Log and Event Viewer when a workflow ran successfully if the Invoke Workflow File activity with the Isolated option was used to invoke a file that contained a Message Box activity. This issue occurred in versions prior to 20.4.
• Fixed an issue that caused multiple Get Asset requests to Orchestrator to fail.
• The Extension property can now be used when selecting the output of the Get File Info activity as well as for the current file in the iteration when working inside a For Each File in Folder activity.

V20.4

Release Date: 27 April 2020

New Features and Improvements

The While and Do While activities have suffered a makeover, extending their functionality. You can now insert Break / Exit Loop and Continue / Skip Current activities in their bodies, enabling you to break loops, or continue to the next cycle. This does not cause any breaking change to your old workflows, as the older versions of these activities still function properly, albeit without the new functionalities.

Also, to complement the Orchestrator Storage feature, we have created activities to work with Orchestrator in performing basic CRUD actions:

• Delete Storage File
• Download Storage File
• Read Storage Text
• List Storage Files
• Upload Storage File
• Write Storage Text

The Invoke Process and Run Parallel Process activities now have a new property, Entry Point Workflow, which enables you to designate the first workflow that is to be executed when invoking the process.

The Download File activity detects a file download from any application and waits for the download to complete before any further processing of the file in the automation.

V20.2.0

V19.10.1

Release Date: 11 November 2019

New Features and Improvements

As of this release, the Project Settings feature has been implemented in the System activities pack, enabling you to set project-wide configurations for the activities in this package.

Most of the Orchestrator activities have a new property, FolderPath, which, paired with the Folders feature in Orchestrator, enables you to specify if the Transaction Item you want to process is located in a folder different than the default one.

We have further increased language support by adding Turkish, Portuguese (Portugal), Spanish (Latin America), and Spanish (Spain) to the list of languages present in the UiPath Platform.

A new activity, called Run Parallel Process has been added to the System package, enabling you to run a specified process in Orchestrator, with the ability to pass it a list of input arguments.

Bug Fixes

• The Postpone Transaction Item activity did not properly function with older versions of Orchestrator.
• Fixed an issue that caused a memory leak when passing a UiElement variable as an input argument to an Invoke Workflow File activity.

Improvements

Three new languages, German, South Korean, and Portuguese are available for the UiPath.System.Activities package.

V19.7.0

Release Date: 16 July 2019

New Features and Improvements

The Invoke Code activity now also supports C#, which has been added to our arsenal of programming languages that can be directly invoked from UiPath workflows. You can make the switch between the default VB.NET and C# by using the new Language property.

V19.4.1

Release Date: 26 June 2019

Improvements

We want to reach out to the entire world and make automation a language everyone can speak. So, starting with this release, the entire platform is available in Chinese.

Note: Chinese can only be used in this pack when installed in Studio v2019.4.4 or v2019.7 or above.

V19.6.0

Release Date: 24 June 2019

New Features and Improvements

The new Invoke Process activity enables you to begin the execution of any process that is present on the machine you are working on directly from your current workflow.

The recently developed Multiple Assign activity helps you clear the clutter in your workflows by letting you use a single activity for multiple assign actions.

V19.5.0

Release Date: 21 May 2019

New Features and Improvements

The activity has been created with the purpose of adding VBScript to the list of the languages you can directly use into your processes.

The ItemInformationCollection property has been added to the Add Queue Item activity, enabling you to import an entire dictionary as information for queue items.

The Invoke Workflow File activity now has the ability to import arguments, as well as open the workflow that it is invoking, directly from two new buttons in the body of the activity.

V19.4.0

Release Date: 25 April 2019

New Features and Improvements

Our goal is to simplify the way you interact with Orchestrator, so we've implemented the possibility of adding multiple queue items into a new activity, Bulk Add Queue Items.

Optimising the way queue items are processed, the new Wait Queue Item activity can notify Orchestrator it is ready to receive a queue item, and then wait for Orchestrator to add an item to that queue, eliminating the need for multiple retries.

Bug Fixes

• Fixed an issue which caused the Get Transaction Item activity to return an error at runtime.
• The DeferDate and DueDate properties were not logged in the Output panel at runtime.

V19.3.0

Release Date: 20 February 2019

New Features and Improvements

The Reference and FilterStrategy properties have been added to the Get Transaction Item activity, enabling you to filter the Transaction Item you want to retrieve by its Reference.

With simplification in mind, we have removed the Multiline and Singleline check boxes from the Regex Builder Wizard. No worries, as this does not cause a breaking change, because the Singleline and Multiline options are still available in the RegexOptions property field.

Breaking Changes

• Due to some internal dependencies being updated, starting with this version, the minimum required version of Studio for using this package has changed to v2018.4.4 or v2019.2 or above.

V19.2.0

Release Date: 18 February 2019

New Features and Improvements

We have developed a RegEx Builder Wizard wizard which gives you the ability to harness the power of Regular Expressions with a simple and easy to use UI. This wizard can be accessed from the body of the IsMatch, Matches, and Replace activities.

The Orchestrator HTTP Request activity has been improved and is now able to retrieve the headers of the requests it performs.

Bug Fixes

• When importing arguments in the Invoke Workflow File activity, the names of the values were imported but the values were left empty.

V18.4.2

Release Date: 10 January 2019

Improvements

This new year brings two more languages in the entire UiPath Platform - French and Russian. Since we layed down the foundations of localization in our previous release, we are continuing our efforts in bringing you a more immersive experience and lowering the language barrier bit by bit.

V18.4.1

Release Date: 7 December 2018

New Features and Improvements

To facilitate identifying which step the Robot is performing at any given time, we have created the Report Status activity, which enables you to create a custom status message that is displayed in the Robot Tray at any point in the execution of a workflow.

Also, dark times ahead, the Dark Theme is now available, in its beta version, on all of the activities and wizards in this package.

V18.3.0

Release Date: 22 October 2018

New Features and Improvements

The Core Activities Package is now split into two distinct packs: UIAutomation and System. The first contains all the activities that mimic human interaction, such as Click or Type Into while the latter sums up all the blocks required for building an automation, from invoking another workflow to logging a custom message in Orchestrator.

This change was made so that both in present and future versions, you can reference any version of the UIAutomation and System packages as dependencies for your projects, completely independent of Studio. This is a step forward for being able to update UiPath Platform components without worrying about how they affect your automations.

UiPath.Core.Activities V2018.2

Release Date: 22 May 2018

New Features and Improvements

We've added a new Continue activity to the Core pack. It enables you to streamline conditions inside a For Each loop, without nesting If activities, by skipping iterations.

Four new activities have been created for the enhanced manipulation of DataTable variables:

• Lookup Data Table - Modeled after the Excel VLOOKUP function, it searches for relative cell values in a data table.
• Filter Data Table - Enables you to select filtering conditions for a data table with the help of a wonderful wizard.
• Sort Data Table - Sorts a data table in ascending or descending order based on the values in an indicated column.
• Remove Duplicate Rows - Removes the duplicate rows from a specified DataTable variable.
