 ## Repo Status: Tier 2
 
 This is a "tier 2" repo, which means it's a repo we care about, but don't apply the same level of rigor as a "tier 1" repo. All work is done through pull requests and must pass continuous integration, but the peer review process is much lighter, and our reaction times to issues will not be as fast as tier 1 repositories.

-## Releases
-
-We are _not_ committed to publishing releases for the FFI on a schedule or in tandem with the latest version of [iroh](https://github.com/n0-computer/iroh), but we try. There may be a gap between the latest version of `iroh` (or the latest version of `iroh-ffi` that is released on GitHub), and the matching versions of the Python or Swift ffi languages that are published.
-
-If there currently is a gap, and you need a published Python or Swift package, please file an issue or reach out to us on our [discord](https://discord.gg/B4pzE3usDC).
