NI LabVIEW 2025 Q1 (25.0.0.49247-0+f95) with Drivers

LabVIEW 2025 Q1 Features and Changes - Date: January 23, 2025

.NET (Core) 8.0 Support
LabVIEW 2025 Q1 supports loading and running .NET 8.0 assemblies on Windows. The following features are also supported with .NET 8:
- Building applications, packed libraries, and source distributions.
- Defining and using static properties and methods.
Note: The .NET Container, registering VIs for event callbacks, and building .NET assemblies, are not yet supported with .NET 8.
Python Support
LabVIEW 2025 Q1 supports Python 3.11 and 3.12.
Note: LabVIEW 2025 will continue to support Python 3.9 and 3.10.
Changes to Compare VIs and Other LabVIEW Files
LabVIEW 2025 Q1 adds the HTML format for VI comparison reports. These reports include:
- Annotated images of differences, including different colors for additions, modifications, and removals.
- Images of changed VI icons and connector panes.
- Collapsible sections to help focus on the remaining differences during reviews.
Interactive comparison of VIs also has new annotations and buttons to copy images of differences to the clipboard. You can easily use these features in change comments, such as in Pull Requests with Git.
Project, library, and class files now contain better property labels and less redundant information. It makes it easier for you to review changes using third-party tools for text files.
New Row Options for Listbox, Multicolumn Listbox, Table, and Tree Controls
LabVIEW 2025 Q1 adds the following new options to listbox, multicolumn listbox, table, and tree controls:
- Added Word Wrap option. This option causes text in a cell to display in multiple lines if the column is not wide enough to display the complete text. This option will work best when used in combination with Autosize Row Height.
- Added alternating row background color option. This option makes it easier to associate text with the correct row, especially when the control is not showing horizontal lines. In high contrast themes, this feature is disabled when using system colors for both the text and the background color.



New Properties, Methods, and Events
LabVIEW 2025 Q1 includes the following new properties, methods, and events:
- The Project and Library classes include the following new property:
. Save Version (read only) - Returns the save version of the project or library.
- The Project class includes the following new method:
. Set Project Save Version - Sets the save version of the project. Version is specified as a short form LabVIEW version string, such as 24.0 representing LabVIEW 2024 Q1. The oldest supported version is 17.0. This method will load all project items. The items will prompt to be saved on close if not already saved in a compatible version.
- The Library class includes the following new method:
. Set Library Save Version - Sets the save version of the library. Version is specified as a short form LabVIEW version string, such as 24.0 representing LabVIEW 2024 Q1. The oldest supported version is 17.0. This method will load all library and class items. The items will prompt to be saved on close if not already saved in a compatible version.
- The Listbox, Multicolumn Listbox, Table, and Tree classes include the following new properties:
. Word Wrap - Determines whether the height of a row is based on explicit lines or wrapped text.
. Alternating Row Colors - Row background colors alternate to make row size and boundaries more obvious.
. Alternate Row Background Color - Background color used to draw alternate rows.
Additional Changes
- The LabVIEW Style Guide is now in the LabVIEW Wiki. For information about the LabVIEW Style Guide, refer to the Related information.





LabVIEW (Laboratory Virtual Instrument Engineering Workbench)is a graphical programming language that uses icons instead of lines of text to create applications. In contrast to text-based programming languages that use instructions to determine the order of program execution, LabVIEW uses dataflow programming. In data flow programming, the flow of data through the nodes on the block diagram determines the execution order of the VIs and functions. VIs, or virtual instruments, are LabVIEW programs that imitate physical instruments. In LabVIEW, you build a user interface by using a set of tools and objects. The user interface is known as the front panel. After you build the front panel, you add code using graphical representations of functions to control the front panel objects. You add this graphical code, also known as G code or block diagram code, to the block diagram. The block diagram somewhat resembles a flowchart. The block diagram, front panel, and graphical representations of code compose a VI.

Introduction to the LabVIEW+ Suite

We're excited to announce the release of the NI LabVIEW+ Suite. It's a suite of LabVIEW, plus, more NI software that provides purpose-built tools for automating measurement, analysis, and test. The software works together to save you time.
Emersonis a global technology and software company providing innovative solutions for the world's essential industries. Through its leading automation portfolio, including its majority stake in AspenTech, Emerson helps hybrid, process and discrete manufacturers optimize operations, protect personnel, reduce emissions and achieve their sustainability goals.
(October 11, 2023) - Emerson has announced it has closed its acquisition of NI (National Instruments), a leading provider of software-connected automated test and measurement systems. The acquisition of NI advances Emerson's position as a global automation leader and expands its opportunity to capitalize on key secular trends like nearshoring, digital transformation, and sustainability and decarbonization. NI brings a portfolio of software, control and intelligent devices that is expected to accelerate Emerson's revenue growth aligned to its 4-7% through the cycle organic growth target.
