• Simplify internal concat implementation. Removes some unnecessary unsafe code.

• Improve macro performance. Improves performance of the macro particularly when concatenating a large number of strs/slices. This change requires the MSRV to be increased to Rust 1.66.

October 5th, 2024

• Reduce MSRV to Rust 1.60. Removes usage of MaybeUninit::zeroed() which lowers the MSRV to Rust 1.60.

• Allow slice concatenation without initial value. This change removes the need to add the initializer for non-number types when calling concat_slices!. Instead of having to write something like this:

  concat_slices!([(0, 0, 0); (u8, u8, u8)]: /* ... */);
  

  You can just write

  concat_slices!([(u8, u8, u8)]: /* ... */);
