 * The library name passed to `ccall` or `@ccall` can now be an expression involving
   global variables and function calls. The expression will be evaluated the first

+* `ꜛ` (U+A71B), `ꜜ` (U+A71C) and `ꜝ` (U+A71D) can now also be used as operator
+  suffixes. They can be tab-completed from `\^uparrow`, `\^downarrow` and `\^!` in the REPL

 * The syntax `import A as B` (plus `import A: x as y`, etc.) can now be used to

 Standard library changes

 * The `nextprod` function now accepts tuples and other array types for its first argument ([#35791]).

 * For consistency `haskey(r::RegexMatch, i::Integer)` has also been added and returns if the capture group for `i` exists ([#37300]).
 * A new standard library `TOML` has been added for parsing and printing [TOML files](https://toml.io) ([#37034]).
+* A new standard library `Downloads` has been added, which replaces the old `Base.download` function with `Downloads.download`, providing cross-platform, multi-protocol, in-process download functionality implemented with [libcurl](https://curl.haxx.se/libcurl/) ([#37340]).
+* The `Pkg.BinaryPlatforms` module has been moved into `Base` as `Base.BinaryPlatforms` and heavily reworked.
+  Applications that want to be compatible with the old API should continue to import `Pkg.BinaryPlatforms`,
+  however new users should use `Base.BinaryPlatforms` directly. ([#37320])
+* The `Pkg.Artifacts` module has been imported as a separate standard library.  It is still available as
