 Important caveats for host applications:
 
-- Parrhesia is pre-beta; expect some public API and config churn while we prepare for beta.
+- Parrhesia is beta software; expect some API and config churn as the runtime stabilizes.
 - Parrhesia currently assumes a single runtime per BEAM node and uses globally registered process names.
 - The defaults in this repo's `config/*.exs` are not imported automatically when Parrhesia is used as a dependency. A host app must set `config :parrhesia, ...` explicitly.
 - The host app is responsible for migrating Parrhesia's schema, for example with `Parrhesia.Release.migrate()` or `mix ecto.migrate -r Parrhesia.Repo`.
