Changes / improvements

• Removed Foo { 1, 2 } initializer.
• Changed Foo(<int>) to Foo {int}.
• Removed {| |} expression blocks.
• Removed macro &ref and $varef parameters.
• Removed $vaexpr(0) syntax in favour of $vaexpr[0]
• Enum does not cast to/from an integer (its ordinal).
• Removed use of void! for main, test and benchmark functions.
• Removed $or, $and, $concat compile time functions.
• Removed @adhoc attribute.
• Disallow inline use of nested generics (e.g. List{List{int}}.
• Remove .allocator = allocator syntax for functions.
• Remove @operator(construct).
• Removal of "any-switch".
• Allow swizzling assign, eg. abc.xz += { 5, 10 };
• Added $$wstr16 and $$wstr32 builtins.
• $foreach "()" replaced by trailing ":" $foreach ($x, $y : $foo) -> $foreach $x, $y : $foo:
• $for "()" replaced by trailing ":" $for (var $x = 0; $x < FOO; $x++) -> $for var $x = 0; $x < FOO; $x++:
• $switch "()" replaced by trailing ":" $switch ($Type) -> $switch $Type:
• Empty $switch requires trailing ":" $switch -> $switch:
• Rename @return! to @return? and change syntax to require ":" after faults.
• Remove if (catch foo) { case ... } syntax.
• Remove [?] syntax.
• Change int! to int? syntax.
• New fault declaration using faultdef.
• Enum associated values can reference the calling enum.
• Improve error message on foo ?? io::EOF with missing '?' #2036
• Make @public import recursive. #2018
• Fault nameof prefixes the first last module path, for instance std::io::EOF is rendered as io::EOF.
• Rename def to alias.
• Change distinct -> typedef.
• Order of attribute declaration is changed for alias.
• Added LANGUAGE_DEV_VERSION env constant.
• Rename anyfault -> fault.
• !!foo now works same as as ! ! foo.
• Temp allocator now supports more than 2 in-flight stacks.
• Printing stacktrace uses its own temp allocator.
• Allow inferred type on body parameters. E.g. @stack_mem(1024; alloc) { ... };
• Use @pool_init() to set up a temp pool on a thread. Only the main thread has implicit temp pool setup.
• tmem is now a variable.
• Compile test and benchmark functions when invoking --lsp #2058.
• Added @format attribute for compile time printf validation #2057.
• Formatter no longer implicitly converts enums to ordinals.

Fixes

• Fix address sanitizer to work on MachO targets (e.g. MacOS).
• Post and pre-decrement operators switched places for vector elements #2010.
• Aliases were incorrectly considered compile time constants.
• FreeBSD libc stat definitions were incorrect.
• Atomic max was incorrect.
• "+".to_float() would panic.
• import can now both be @public and @norecurse.
• Crash when trying to convert a struct slice to a vector #2039.
• Crash resolving a method on Foo[2] when Foo is distinct #2042.
• Bug due to missing cast when doing $i[$x] = $z.
• Incorrectly allowed getting pointer to a macro #2049.
• &self not runtime null-checked in macro #1827.
• Bug when printing a boolean value as an integer using printf.
• Show error when a generic module contains a self-generic type.
• "Single module" was not enforced when creating a static library using as a project target.

Stdlib changes

• new_* functions in general moved to version without new_ prefix.
• string::new_from_* changed to string::from_*.
• String.to_utf16_copy and related changed to String.to_utf16.
• String.to_utf16_tcopy and related changed to String.to_temp_utf16
• mem::temp_new changed to mem::tnew.
• mem::temp_alloc and related changed to mem::talloc.
• mem::temp_new_array changed to mem::temp_array.
• Add ONHEAP variants for List/HashMap for initializing global maps on the heap.
• Remove Vec2 and other aliases from std::math. Replace .length_sq() with sq_magnitude()
• Change all hash functions to have a common hash function.
• @wstring, @wstring32, @char32 and @char16 compile time macros added.
• Updates to Atomic to handle distinct types and booleans.
• Added math::iota.
• @pool no longer takes an argument.
• Allocator interface removes mark and reset.
• DynamicArenaAllocator has changed init function.
• Added BackedArenaAllocator which is allocated to a fixed size, then allocates on the backing allocator and supports mark/reset.
• AnyList now also defaults to the temp allocator.
• os::getcwd and os::get_home_dir requires an explicit allocator.
• file::load_new and file::load_path_new removed.
• os::exit and os::fastexit added.
