Release v0.14.0 · git-pkgs/git-pkgs 

## Assistant

## Assistant

There aren't two of each - there are two *architectures* per operating system:

- **amd64** — Intel/AMD x86-64 chips
- **arm64** — ARM chips (Apple Silicon, AWS Graviton, Snapdragon, etc.)

So it's 3 OSes × 2 architectures = 6 binaries. Standard cross-compilation matrix for a Go project.

## User

oh 

## Assistant

Yeah, Go makes it easy to cross-compile for all those targets so you might as well ship them all.

## User

amd and arm read so similar

## Assistant

They really do. Doesn't help that they're both followed by "64" either. One of those naming choices that made sense to engineers and no one else.
