NI LabVIEW 2021 SP1 F1

软件开发商 National Instruments 很高兴地宣布推出 LabVIEW 2021 SP1 F1 (21.1.1)。此更新包括对上一版本中各种用户报告的问题的修复，提供了更稳定的整体体验。

LabVIEW 2021 SP1 F1 错误修复——日期：2022 年 4 月 26 日

1887820  LabVIEW 2021 SP1 内存泄漏
LabVIEW 2021 SP1 会导致某些应用程序的内存使用量随着时间的推移而不必要地增加。
解决方法：您可以通过在 LabVIEW INI 文件中添加“MemoryManger.UseMasterPointerPool = FALSE”来禁用导致内存泄漏的性能优化。LabVIEW 2021 SP1 f1 补丁通过默认禁用性能优化来修复该问题。

LabVIEW（实验室虚拟仪器工程工作台） 是一种图形化编程语言，它使用图标而不是文本行来创建应用程序。与使用指令确定程序执行顺序的基于文本的编程语言相比，LabVIEW 使用数据流编程。在数据流编程中，通过程序框图上节点的数据流决定了VI和函数的执行顺序。VI 或虚拟仪器是模拟物理仪器的 LabVIEW 程序。

在 LabVIEW 中，您可以使用一组工具和对象来构建用户界面。用户界面称为前面板。构建前面板后，您可以使用函数的图形表示添加代码来控制前面板对象。您将此图形代码（也称为 G 代码或框图代码）添加到框图中。该框图有点类似于流程图。程序框图、前面板和代码图形表示构成了一个 VI。

LabVIEW 是我们不断扩展的软件组合的重要组成部分。为了在 LabVIEW 的成功基础上再接再厉，我们开发了 NXG 平台，该平台支持了一系列全新的产品，例如 NXG Web 模块、SystemDesigner、FlexLogger、InstrumentStudio、VeriStand 和数字模式编辑器。您告诉我们这些基于 NXG 的解决方案具有巨大的价值，我们同意。

我们还构建了基于 NXG 平台的新产品 LabVIEW NXG。虽然您的反馈是积极的，并且您对在 LabVIEW NXG 中看到的内容感到兴奋，但您也与我们分享了您对迁移到全新 LabVIEW 产品的一些担忧。尽管我们已经缓解了其中一些问题，但我们同意并希望使您能够专注于解决您未来的测试和测量需求。

这就是我们决定采取以下步骤的原因：

我们将把 NXG 平台的优势集成到我们的 LabVIEW 2021(+) 代码库中，从而实现两全​​其美。这意味着集中我们对 LabVIEW 的投资，使我们能够在未来几年为 LabVIEW 用户提供更多价值。
我们将继续推进我们基于 NXG 的解决方案组合，例如 NXG Web 模块、SystemDesigner，以及我们扩展的基于配置的产品套件，例如 FlexLogger 和 VeriStand。作为这一承诺的一部分，您可以期待看到 NXG Web 模块和 SystemDesigner 集成到我们产品组合的其他部分中。
我们将停止 LabVIEW NXG 的开发工作，并在 2021 年发布最终版本——LabVIEW NXG 5.1。我们不会从 2022 年开始发布新版本的 LabVIEW NXG。

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.
