 Note: These instructions are for adding to or improving functionality in the base library. Before getting started, it can be helpful to discuss the proposed changes or additions on the [Julia Discourse forum](https://discourse.julialang.org) or in a GitHub issue---it's possible your proposed change belongs in a package rather than the core language. Also, keep in mind that changing stuff in the base can potentially break a lot of things. Finally, because of the time required to build Julia, note that it's usually faster to develop your code in stand-alone files, get it working, and then migrate it into the base libraries.

   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
+  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])
+* When a method with keyword arguments is displayed in the stack trace view, the textual
+  representation of the keyword arguments' types is simplified using the new
+  `@Kwargs{key1::Type1, ...}` macro syntax ([#49959]).
 
 Compiler/Runtime improvements
 -----------------------------
 
 * 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]).
+* [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]).

    It can also be accessed using the unicode character `∜`, which can be typed by `\fourthroot<tab>` ([#48899]).
+* `Libc.memmove`, `Libc.memset`, and `Libc.memcpy` are now defined, whose functionality matches that of their respective C calls.
