* In Linux and Windows, `--threads=auto` now tries to infer usable number of CPUs from the
process affinity which is set typically in HPC and cloud environments ([#42340]).
* The `--threads` command-line option now accepts `auto|N[,auto|M]` where `M` specifies the
number of interactive threads to create (`auto` currently means 1) ([#42302]).

Multi-threading changes
-----------------------

* `Threads.@spawn` now accepts an optional first argument: `:default` or `:interactive`.
An interactive task desires low latency and implicitly agrees to be short duration or to
yield frequently. Interactive tasks will run on interactive threads, if any are specified
when Julia is started ([#42302]).
