What's the minimal rust version?

[Endle]

I'm using rust 1.49.0

When installing this package, I hit E0658

$ cargo install cargo-release

error[E0658]: use of unstable library feature 'str_split_once': newly added

What's the minimal rust version for cargo-release?

Thank you

1.52.

I recommend checking CI as the definitive in this. Even if we document it somewhere, it is likely to be missed as we update CI.

Granted, that can be confusing because we have a stale travis file that we aren't using.

Let me remove that travis config to avoid confusion.
