Version 13.1 is released on Wolfram Cloud.

@xzczd I still remember the 6 principles of compilation you shared. Now the compilation system has been updated a lot and is obviously more powerful than the previous one, can you please president and share it again?

I noticed another very noticeable improvement in the compilation system of version 13.1

@yode Honestly speaking I haven't looked into FunctionCompile so far. Given the EXPERIMENTAL mark is still there, perhaps it's too early to dive into it…

@xzczd After several versions, the new version of the compilation system has really come a long way indeed

How's your experience with the W Paclet Repository folks?

@Kuba I'd like to hear, too. I'm thinking of using it.

Random factoid: On my Mac M1 Max, in Mma, vectorized addition and multiplication of 10^6 - 10^7 complex numbers is consistently 15% faster than the addition and multiplication of twice as many real numbers. Integers are about the same speed as reals. I used RepeatedTiming; 10^7 numbers gives very consistent results; 10^6 sometimes varies far from the average. (Addition & multiplication of the same type of number take the same time.)

@MichaelE2 same!

Simplify is so gullible -- give it a False Assumption and it will believe anything is True!

Simplify[1 > 2, False]

(* True *)

soon to be the subject of a hot question, unless someone here can point me to an old one on the same topic :)
