Glad to announce the first beta for the 2.104.0 release, ♥ to the 36 contributors.

This release comes with 11 major changes, including:

• In the compiler, User Defined Attributes now parse template arguments.
• In the standard library, std.typecons.Rebindable now supports all types
• In dub, new properties cSourcePaths and cImportPaths have been added to pass C sources and add additional search paths for C headers to the compiler.

alias Tint = int;
@Tint void f();

Here says not to use basic types as attributes, but the following example give it another basic type?

@int void f();

@int void f();

The keyword here in the changelog is: would; that is to say, the compiler previously rejected basic types, but now they are accepted.

I'll have a think about how that entry could be rephrased to avoid confusion, though you are welcome to raise your own pull request to clarify the wording.

Thank you for your reply. I understand it.

@int void f();

That's a half baked change, it would have been better to go a bit further:

previously

alias Tint = int;
@Tint void f();

now

@int void f();

nice. But previously

alias Tint = int;
@Tint(1) void f();

now

@int(1) void f(); // Not Good

that's unfortunately still an error.

A couple days ago I ran into an issue that was solved by https://issues.dlang.org/show_bug.cgi?id=23846 so I upgraded to this beta. I just initialized a dub project to try to use mir.stat

import std.stdio;
import mir.stat;

void main()
{
	writeln("Edit source/app.d to start your project.");
}

and ran into the following linker errors:

I think that worked for you because although you have set mirstat as a dependency, you are not actually linking against it. Try import mir.stat; into app.d and rebuild.

Also it might be a macOS specific issue since the original problems I faced didn't materialize on my Debian 11 VM.
