Those are not commits, they are [UUIDs](https://en.m.wikipedia.org/wiki/Universally_unique_identifier).

If you want to add compatibility constraints, see [6. Compatibility · Pkg.jl](https://julialang.github.io/Pkg.jl/v1/compatibility/)

If you want to install a specific version, use e.g.

```bash
pkg> add Example@0.5

```
