This package is part of the Frontera SDK, @frontera-sdk/core, and re-exports @frontera-sdk/core/functions. It is published on every release so Apps that import @frontera-sdk/functions keep working and keep getting fixes.
New code imports from @frontera-sdk/core:
// before
import { … } from '@frontera-sdk/functions/…'
// after
import { … } from '@frontera-sdk/core/functions/…'
Every subpath keeps its name: @frontera-sdk/functions/<subpath> is @frontera-sdk/core/functions/<subpath>. See the README of @frontera-sdk/core.
