arti/doc/semver_status.md

Semver tracking

This is a helpful file that we use for checking which crates will have breaking or nonbreaking API changes in the next release of Arti.

For each crate, please write "BREAKING" if there is an API change that counts as breaking in semver, and "MODIFIED" if there is a backward-compatible API change.

You can change from MODIFIED to BREAKING, but never from BREAKING to MODIFIED.

You don't need to list details; this isn't the changelog.

Don't document other changes in this file.

We can delete older sections here after we bump the releases.

Since Arti 0.4.0
