So far we developed in rather old LabVIEW versions, even for Windows 11. Most programs are in LV2017, a single release in LV2021 and a few programs still running in LV2011. Almost all programs use VISA and some of them DAQ-mx. This worked well until recent times.
But now there are problems arising that we believe to come from old drivers. For example, we have a datalogger program in LV2017 that communicates with a network of instruments using VISA over serial or TCP/IP connections. This program now freezes with new computers after a variable running time - from 30 minutes to a few hours. It did not used to hang in earlier versions of the OS. I made a test with LV2021 and the latest VISA that indicates that this hanging does not take place (at least, not so quickly).
So we need to upgrade to a new version. LV2021 does not appear to be a good choice though, because it's somewhat aged and offiicially not compatible with Windows 11.
Normally for the switch I would choose the last "patched" version, namely, by now, LabVIEW 2024 Q3.
Do you know of any reason to stay away from this version - or conversely to go straight to LabVIEW 2025?
Thank you in advance for any suggestion.

We have been using LabVIEW 2024 Q3 64-bit on multiple projects. The updates to the IDE for Highlight Execution are a huge bonus in my opinion. LabVIEW 2025 Q1, as long as you install the patches, has been stable in our testing but we haven't used it as extensively as 2024 Q3.
In my opinion I would move to 2025 Q1. It will be binary compatible with Q3 that comes out in July so you can just update to then when it comes. The benefits of 2025 Q1 as a long term version are .NET 8 support, Python 3.11 and 3.12 support (not sure how important any of that is to you though). Also NI is way quicker to update the most recent release so that's an added bonus if issues are discovered.

In contrast I've heard that everything 2024 and newer have a lot of subtle weird bugs that need to be addressed. Caveat is that I haven't had a chance to do my own evaluation.

I've been using 2024Q3 64-bit since it was released. The main issues I had have been patched. Due to license server restrictions, I am not able to upgrade to 2025.

Early versions of 2024 were iffy. We have been using 2024Q3 64-bit for a while now it it seems more stable.
