parser if necessary (and if you find this necessary, please file an issue) ([#46372]).

that significantly improves load and inference times for heavily overloaded methods that
dispatch on Types (such as traits and constructors).
* The "h bar" `ℏ` (`\hslash` U+210F) character is now treated as equivalent to `ħ` (`\hbar` U+0127).
* The `@simd` macro now has a more limited and clearer semantics, it only enables reordering and contraction
* The `@simd` macro now has more limited and clearer semantics: it only enables reordering and contraction
of floating-point operations, instead of turning on all "fastmath" optimizations.
If you observe performance regressions due to this change, you can recover previous behavior with `@fastmath @simd`,
if you are OK with all the optimizations enabled by the `@fastmath` macro. ([#49405])

Compiler/Runtime improvements

* Updated GC heuristics to count allocated pages instead of individual objects ([#50144]).

* Updated GC heuristics to count allocated pages instead of individual objects ([#50144]).
* The `@pure` macro is now deprecated. Use `Base.@assume_effects :foldable` instead ([#48682]).
* The mark phase of the Garbage Collector is now multi-threaded ([#48600]).
* The mark phase of the garbage collector is now multi-threaded ([#48600]).
* [JITLink](https://llvm.org/docs/JITLink.html) is enabled by default on Linux aarch64 when Julia is linked to LLVM 15 or later versions ([#49745]).
This should resolve many segmentation faults previously observed on this platform.

Command-line option changes
---------------------------

* New option `--gcthreads` to set how many threads will be used by the Garbage Collector ([#48600]).
The default is set to `N/2` where `N` is the amount of worker threads (`--threads`) used by Julia.

Multi-threading changes

Build system changes
--------------------

* New option `--gcthreads` to set how many threads will be used by the garbage collector ([#48600]).
The default is `N/2` where `N` is the number of worker threads (`--threads`) used by Julia.

New library functions
---------------------

* `tanpi` is now defined. It computes tan(πx) more accurately than `tan(pi*x)` ([#48575]).
* `fourthroot(x)` is now defined in `Base.Math` and can be used to compute the fourth root of `x`.
It can also be accessed using the unicode character `∜`, which can be typed by `\fourthroot<tab>` ([#48899]).

New library features

* The `initialized=true` keyword assignment for `sortperm!` and `partialsortperm!`
is now a no-op ([#47979]). It previously exposed unsafe behavior ([#47977]).
* `binomial(x, k)` now supports non-integer `x` ([#48124]).
* A `CartesianIndex` is now treated as a "scalar" for broadcasting ([#47044]).

* `parent` and `parentindices` support `SubString`s.
* `replace(string, pattern...)` now supports an optional `IO` argument to
write the output to a stream rather than returning a string ([#48625]).

Standard library changes

the output of `cholesky`.

#### REPL

#### Test

non-boolean value in the same way as a non-broken test. ([#47804])
