Comparison between old and new editions；Numba

[LG-commits]

Hello, dear author.

I'm reaching out to inquire about the specifics of the updates and changes introduced in the newer versions of your project compared to the older ones. Could you please guide me on where to find detailed information regarding these updates ?

Additionally, I'm particularly interested in knowing from which version you stopped using Numba for speeding up the runtime. When applying the model to larger scales, I noticed significant differences in running speeds between different versions.

Thank you for your assistance.

Best regards
