Span::record method, as well as updating the minimum tracing-core version
and several documentation improvements.

Fixed

• Incorrect docs in dispatcher::set_default (#2220)
• Compilation with -Z minimal-versions (#2246)

Added

• Support for owned values and fat pointers in Span::record (#2212)
• Documentation improvements (#2208, #2163)

Changed

• tracing-core: updated to 0.1.29

Thanks to @fredr, @cgbur, @jyn514, @matklad, and @CAD97 for contributing to this
release!

tracing-subscriber 0.3.15

This release fixes a bug where the reload layer would fail to pass through
max_level_hint to the underlying layer, potentially breaking filtering.

Fixed

• reload: pass through max_level_hint to the inner Layer (#2204)

Thanks to @guswynn for contributing to this release!

tracing-subscriber 0.3.14

This release fixes multiple filtering bugs in the Layer implementations for
Option<impl Layer> and Vec<impl Layer>.

Fixed

• layer: Layer::event_enabled implementation for Option<impl Layer<S>>
  returning false when the Option is None, disabling all events globally
  (#2193)
• layer: Layer::max_level_hint implementation for Option<impl Layer<S>>
  incorrectly disabling max level filtering when the option is None (#2195)
• layer: Layer::max_level_hint implementation for Vec<impl Layer<S>>
  returning LevelFilter::ERROR rather than LevelFilter::OFF when the Vec
  is empty (#2195)

Thanks to @CAD97 and @guswynn for contributing to this release!

tracing-opentelemetry 0.17.4

This release adds optional support for recording std::error::Errors using
[OpenTelemetry's semantic conventions for exceptions][exn-semconv].

Added

• Layer::with_exception_fields to enable emitting exception.message and
  exception.backtrace semantic-convention fields when an Error is recorded
  as a span or event field (#2135)
• Layer::with_exception_field_propagation to enable setting exception.message and
  exception.backtrace semantic-convention fields on the current span when an
  event with an Error field is recorded (#2135)

Thanks to @lilymara-onesignal for contributing to this release!

tracing-attributes 0.1.22

This release fixes an issue where using the err or ret arguments to
#[instrument] along with an overridden target, such as

#[instrument(target = "...", err, ret)]

would not propagate the overridden target to the events generated for
errors/return values.

Fixed

• Error and return value events generated by #[instrument(err)] or
  #[instrument(ret)] not inheriting an overridden target (#2184)
• Incorrect default level in documentation (#2119)

Thanks to new contributor @tbraun96 for contributing to this release!

tracing-subscriber 0.3.13

This release of tracing-subscriber fixes a compilation failure due to an
incorrect tracing-core dependency that was introduced in v0.3.12.

Changed

• tracing_core: Updated minimum dependency version to 0.1.28 (#2190)

tracing-subscriber 0.3.12

This release of tracing-subscriber adds a new Layer::event_enabled method,
which allows Layers to filter events after their field values are recorded;
a Filter implementation for reload::Layer, to make using reload with
per-layer filtering more ergonomic, and additional inherent method downcasting
APIs for the Layered type. In addition, it includes dependency updates, and
minor fixes for documentation and feature flagging.

Added

• layer: Layer::event_enabled method, which can be implemented to filter
  events based on their field values (#2008)
• reload: Filter implementation for reload::Layer (#2159)
• layer: Layered::downcast_ref and Layered::is inherent methods
  (#2160)

Changed

• parking_lot: Updated dependency on parking_lot to 0.13.0 (#2143)
• Replaced lazy_static dependency with once_cell ([#2147])

Fixed

• Don't enable tracing-core features by default (#2107)
• Several documentation link and typo fixes (#2064, #2068, #[2077], #2161,
  #1088)

Thanks to @ben0x539, @jamesmunns, @georgemp, @james7132, @jswrenn, @CAD97, and
@guswynn for contributing to this release!

tracing-core 0.1.28

This release of tracing-core adds new Value implementations, including one
for String, to allow recording &String as a value without having to call
as_str() or similar, and for 128-bit integers (i128 and u128). In
addition, it adds new methods and trait implementations for Subscribers.

Added

• Value implementation for String (#2164)
• Value implementation for u128 and i28 (#2166)
• downcast_ref and is methods for dyn Subscriber + Sync,
  dyn Subscriber + Send, and dyn Subscriber + Send + Sync (#2160)
• Subscriber::event_enabled method to enable filtering based on Event field
  values (#2008)
• Subscriber implementation for Box<S: Subscriber + ?Sized> and
  Arc<S: Subscriber + ?Sized> (#2161)

Thanks to @jswrenn and @CAD97 for contributing to this release!
