How do you check or set what software embedded pack you're using?

Question

TL;DR version:Is there a way to set/check the microcontroller software embedded pack you're using (ie stm32wb55 V1.11.1)?I was working on trying to get a Stop2 Low Power mode working and was running into some issues so I checked the forum. I came across as post by @Scott L�hr​ that it was easy as of version 1.8. Below is the thread it discussed this (if you're interested):He had mentioned it could be done in 4 lines:LL_PWR_SetPowerMode(LL_PWR_MODE_STOP2);
LL_LPM_EnableDeepSleep();
__WFI();
sysClkCfg();I tried the code but it didn't recognize the EnableDeepSleep command. I started looking through the *.h files and, sure enough, it wasn't there. I have several different package versions so I created a new project from scratch to see if it was there and it wasn't there in a recent one either. So, the question I eventually came down to was, how do I know what version I'm actually running? Can I switch between versions? I currently don't even know what framework my projects are running on and, as much as I want to get the sleep commands to work (I'm sure it's easy enough), not knowing what version of framework I'm currently running on seems like a potentially bigger issue (depending on changes/updates made in different versions). If you guys could help me find out where I can look to check/set which package I'm using, that would be awesome! I tried searching around in project folders but didn't have any luck. Thanks!

For the STM32WL and some other families, they appear to coincide.> Can I switch between versions? In general, yes, but some things do change between versions that may require changes to your code. I would stick with one version once you get it working unless you need features or big fixes in later version. If you're using CubeMX to regenerate code, switching between package versions is easy.
