Old dog, New tricks

[Frozen]

I have been using LV for twenty (mumble) years and I have learnt two new trick this past couple weeks.

1) how to configure dlls to be bitness antagonistic from some random forum posting that I cannot find atm. The help page is here <https://www.ni.com/docs/en-US/bundle/labview/page/configuring-the-call-library-function-node.html#d7...>

2) Saving for previous versions can be as simple as putting a .lvversion file in your project/directory per Crossrulz post here
The help page is here <https://www.ni.com/docs/en-US/bundle/labview/page/saving-for-a-previous-version.html>

The one thing the help pages fails to mention (or maybe I am just blind) is *when* these awesome trick were introduced and more importantly, what versions of LV these features can be used. Does anyone know what version of LV these tricks features will work?

I am currently using LV 2022 64-bit

In LV2021 32 bit there is no "Save version" option in the project properties.

Officially 2024Q3. 2024Q1 introduced the concept of a "Preview Feature" that can be enabled in the options. This was a preview feature in 2024Q1.

This existed since LabVIEW 2009, the first version to support 64-bit development. It actually seems to be partly present in 8.6, including supporting pointer sized integers, but no 64-bit version for 8.6 was ever released.

Thanks for the info.

Dealing with 32-bit and 64-bit DLLs still antagonizes me!
