* The `extrema` function now accepts a function argument in the same manner as `minimum` and
`maximum` ([#30323]).
* `hasmethod` can now check for matching keyword argument names ([#30712]).
* `startswith` and `endswith` now accept a `Regex` for the second argument ([#29790]).

---------------------

* `getipaddrs()` function returns all the IP addresses of the local machine ([#30349])
* Added `Base.hasproperty` and `Base.hasfield` ([#28850]).
* One argument `!=(x)`, `>(x)`, `>=(x)`, `<(x)`, `<=(x)` has been added for currying,
similar to the existing `==(x)` and `isequal(x)` methods ([#30915]).

Standard library changes

* Added `Base.hasproperty` and `Base.hasfield` ([#28850]).

#### LinearAlgebra

* Added keyword arguments `rtol`, `atol` to `pinv` and `nullspace` ([#29998]).
