# 0.1.26 (April 30, 2021)
### Fixed
- **attributes**: Compatibility between `#[instrument]` and `async-trait`
v0.1.43 and newer ([#1228])
- Several documentation fixes ([#1305], [#1344])
### Added
- `Subscriber` impl for `Box<dyn Subscriber + Send + Sync + 'static>`
([#1358])
- `Subscriber` impl for `Arc<dyn Subscriber + Send + Sync + 'static>`
([#1374])
- Symmetric `From` impls for existing `Into` impls on `span::Current`,
`Span`, and `Option<Id>` ([#1335], [#1338])
- `From<EnteredSpan>` implementation for `Option<Id>`, allowing
`EnteredSpan` to be used in a `span!` macro's `parent:` field ([#1325])
- `Attributes::fields` accessor that returns the set of fields defined
on a span's `Attributes` ([#1331])
