# 0.2.19 (June 25, 2021)

### Deprecated

- **registry**: `SpanRef::parents`, `SpanRef::from_root`, and
  `Context::scope` iterators, which are replaced by new `SpanRef::scope`
  and `Scope::from_root` iterators (#1413)

### Added

- **registry**: `SpanRef::scope` method, which returns a leaf-to-root
  `Iterator` including the leaf span (#1413)
- **registry**: `Scope::from_root` method, which reverses the `scope`
  iterator to iterate root-to-leaf (#1413)
- **registry**: `Context::event_span` method, which looks up the parent
  span of an event (#1434)
- **registry**: `Context::event_scope` method, returning a `Scope`
  iterator over the span scope of an event (#1434)
- **fmt**: `MakeWriter::make_writer_for` method, which allows returning
  a different writer based on a span or event's metadata (#1141)
- **fmt**: `MakeWriterExt` trait, with `with_max_level`,
  `with_min_level`, `with_filter`, `and`, and `or_else` combinators
  (#1274)
- **fmt**: `MakeWriter` implementation for `Arc<W> where &W: io::Write`
  (#1274)
