This branch adds some new documentation in a few places that references
other sections in the docs. This should help make some of the crate's
APIs easier to find. In particular, the crate's top level docs now
summarize the Layer and Filter traits, and link to their individual
docs sections. Additionally, the per-layer filtering section in the
Layer module docs now references some of the concrete Filter
implementations in the filter modules.

# 0.2.21 (September 12, 2021)

This release introduces the [`Filter`] trait, a new API for [per-layer
filtering][plf]. This allows controlling which spans and events are
recorded by various layers individually, rather than globally.

In addition, it adds a new [`Targets`] filter, which provides a
lighter-weight version of the filtering provided by [`EnvFilter`], as
well as other smaller API improvements and fixes.

### Deprecated

- **registry**: `SpanRef::parent_id`, which cannot properly support
  per-layer filtering. Use `.parent().map(SpanRef::id)` instead.
  ([#1523])

### Fixed

- **layer** `Context` methods that are provided when the `Subscriber`
  implements `LookupSpan` no longer require the "registry" feature flag
  ([#1525])
- **layer** `fmt::Debug` implementation for `Layered` no longer requires
  the `S` type parameter to implement `Debug` ([#1528])

### Added

- **registry**: `Filter` trait, `Filtered` type, `Layer::with_filter`
  method, and other APIs for per-layer filtering ([#1523])
- **filter**: `FilterFn` and `DynFilterFn` types that implement global
  (`Layer`) and per-layer (`Filter`) filtering for closures and function
  pointers ([#1523])
- **filter**: `Targets` filter, which implements a lighter-weight form
  of `EnvFilter`-like filtering ([#1550])
- **env-filter**: Added support for filtering on floating-point values
  ([#1507])
- **layer**: `Layer::on_layer` callback, called when layering the
  `Layer` onto a `Subscriber` ([#1523])
- **layer**: `Layer` implementations for `Box<L>` and `Arc<L>` where `L:
  Layer` ([#1536])
- **layer**: `Layer` implementations for `Box<dyn Layer<S> + Send + Sync
  + 'static>` and `Arc<dyn Layer<S> + Send + Sync + 'static>` ([#1536])
- A number of small documentation fixes and improvements ([#1553],
  [#1544], [#1539], [#1524])

Special thanks to new contributors @jsgf and @maxburke for contributing
to this release!
