I need VQFN packages to use them in Microchip Lib for ATmega324PB-Mx device and soon for ATmegaxx8PB devices.
I haven’t found them in LibrePCB Base library.
Is it elsewhere ?
If not, is it planned to create them soon ?

We use mostly https://github.com/LibrePCB/librepcb-parts-generator/ to create footprints. So if you know any Python it would be awesome if you could support us there 
This is important. We want to automate the entire creation of the Base library using python3.5 or better AND using the low level code in librepcb-parts-generator. Then if we ever need to change the file format we can rewrite the low level code, rerun all the scripts and instantly create version 2.
I am currently working on a script for BGA packages. It works for parts that are 100% filled but I need to add a mask to create parts that don’t use all possible ball positions.
When it is done I should be able to also use it for Pin Grid Array parts as well.
OK, I have my bga script working and checked into my fork of librepcb-parts-generator along with the uuids cache file.
It creates 48 Bga packages from the Lattice packaging guide. They are checked into my fork of LibrePCB_Base.lplib. There are pull requests on both repos
