The software developer National Instruments is pleased to announce the availability of LabVIEW 2021 SP1 F1 (21.1.1). This update includes fixes to various user-reported issues from the previous release, providing an overall more stable experience.
LabVIEW 2021 SP1 F1 Bug Fixes – Date: Apr 26, 2022
1887820 LabVIEW 2021 SP1 Leaks Memory
LabVIEW 2021 SP1 causes an increase in the memory usage of some applications unnecessarily over time.
Workaround:You can disable the performance optimization which caused the memory leak by adding “MemoryManger.UseMasterPointerPool = FALSE” to the LabVIEW INI file. LabVIEW 2021 SP1 f1 patch fixes the issue by disabling the performance optimization by default.
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.
LabVIEW is a vital part of our expanding software portfolio. To build on the success of LabVIEW, we developed the NXG Platform which has enabled an entirely new set of offerings such as the NXG Web Module, SystemDesigner, FlexLogger, InstrumentStudio, VeriStand, and Digital Pattern Editor. You’ve told us there’s tremendous value in these NXG-based solutions, and we agree.
We also built a new product, LabVIEW NXG, based on the NXG Platform. While your feedback has been positive and there’s been excitement about what you’re seeing in LabVIEW NXG, you’ve also shared with us some of your concerns around migrating to an entirely new LabVIEW product. And although we’ve mitigated some of these issues, we agree and want to empower you to focus on addressing your future test and measurement needs.
That’s why we’ve decided to take the following steps:
We will integrate the strengths of the NXG platform into our LabVIEW 2021(+) codebase, which will result in the best of both worlds. This means centralizing our investments in LabVIEW in a way that enables us to deliver even more value to LabVIEW users in the years ahead.
We will continue to advance our NXG-based portfolio of solutions such as the NXG Web Module, SystemDesigner, as well as our expanding suite of configuration-based products such as FlexLogger and VeriStand. As part of this commitment, you can expect to see the NXG Web Module and SystemDesigner integrated into other parts of our portfolio.
We will cease development efforts on LabVIEW NXG and release the final version – LabVIEW NXG 5.1 – in 2021. We will not release new versions of LabVIEW NXG starting in 2022.
