That list is not a representative example of what the core devs are doing. It looks to me like it's mostly the work of Oscar Smith, he does a lot of these low-level numerical optimizations. Here are a few more improvements in v1.7 off the top of my head: * Further latency improvements (though much smaller than for 1.6) * Big gains in inference precision for the compiler * The above also unlocks better static analysis * Improved speed for the package manager on Windows * Begin work on adding atomics * Thread-safe RNG I'm sure there is more I've missed - I don't hack on Base Julia much.
