Arduino for STM32

Arduino version 1.8.13
stm32duino version 1.9

While the stm32duino github pages states that various generic stm32l4 boards are supported they do not appear in the drop down menu as seen in my screen shot.

I do see one for L0 but not L4

I am rather new to the stm32duino side of things so what am i missing here do you think?

Yes that is normal.
As you could see on GitHub page (README.md) all the generic L4 supported are from 2.0.0 release. That's why you didn't have them with 1.9.0.
2.0.0 should be released this week.

yes that makes perfect sense thank you
