How to create a new branch from a tag?

Question

I'd like to create a new master branch from an existing tag. Say I have a tag `v1.0`. How to create a new branch from this tag?

Accepted Answer

Wow, that was easier than I thought:

```
git checkout -b newbranch v1.0
```

If running the above command you get an error

warning: refname 'v1.0' is ambiguous. fatal: ambiguous object name: 'v1.0'

this is because you also have a branch with name `v1.0`. In this case specify `tags/` prefix:

```
git checkout -b newbranch tags/v1.0
```
