I'm quite confident that no elsewhere using the tracing_subscriber::CurrentSpan
in the present codebases. Do we need to keep it for the future version?
Otherwise, I think we can remove it and the related thread.rs.
Feel free to point me out if I'm wrong. :)

Yes, this should be removed --- I thought we had already deprecated it in v0.2, but this doesn't appear to be the case. If you have the chance, can we also get a PR against the v0.1.x branch that deprecates the CurrentSpan type? Thanks!

Sure, I'd love to do this.

The `tracing-subscriber::CurrentSpan` should be deprecated in `v0.2.x`.

@Folyd Do you mind suggesting what the replacement for CurrentSpan is? Would also be good to put this into the deprecation docs. Thanks in advance!

I think it has been replaced by Registry API.

# 0.3.0 (Oct 22, 2021)

This is a breaking release of `tracing-subscriber`. The primary breaking
change in this release is the removal of the dependency on the [`chrono`
crate], due to [RUSTSEC-2020-0159]. To replace `chrono`, support is
added for formatting timestamps using the [`time` crate] instead.

In addition, this release includes a number of other breaking API
changes, such as adding (limited) support for `#![no_std]` targets,
removing previously deprecated APIs, and more.

### Breaking Changes

- Removed APIs deprecated in the v0.2.x release series.
- Renamed `Layer::new_span` to `Layer::on_new_span` ([#1674])
- Removed `Layer` impl for `Arc<L: Layer<S>>` and `Arc<dyn Layer<S> +
  ...>` ([#1649])
- Replaced the [`chrono` crate] with the [`time` crate] for timestamp
  formatting, to resolve [RUSTSEC-2020-0159] ([#1646])
- Removed `json` and `env-filter` from default features. They must now
  be enabled explictly ([#1647])
- Changed `FormatEvent::format_event` and `FormatFields::format_fields`
  trait methods to take a `Writer` type, rather than a `&mut dyn
  fmt::Write` trait object ([#1661])
- Changed the signature of the `MakeWriter` trait by adding a lifetime
  parameter ([#781])
  ### Changed

- **layer**: Renamed `Layer::new_span` to `Layer::on_new_span` ([#1674])
- **fmt**: Changed `FormatEvent::format_event` and
  `FormatFields::format_fields` trait methods to take a `Writer` type,
  rather than a `&mut dyn fmt::Write` trait object ([#1661])
- **json**, **env-filter**: `json` and `env-filter` feature flags are no
  longer enabled by default ([#1647])
  ### Removed

- Removed deprecated `CurrentSpan` type ([#1320])
- **registry**: Removed deprecated `SpanRef::parents` iterator, replaced
  by `SpanRef::scope` in [#1431] ([#1648)])
- **layer**: Removed deprecated `Context::scope` iterator, replaced by
  `Context::span_scope` and `Context::event_scope` in [#1431] and
  [#1434] ([#1648)])
- **layer**: Removed `Layer` impl for `Arc<L: Layer<S>>` and `Arc<dyn
  Layer<S> + ...>`. These interfere with per-layer filtering. ([#1649])
- **fmt**: Removed deprecated `LayerBuilder` type ([#1673])
- **fmt**: Removed `fmt::Layer::on_event` (renamed to
  `fmt::Layer::fmt_event`) ([#1673])
- **fmt**, **chrono**: Removed the `chrono` feature flag and APIs for
  using the [`chrono` crate] for timestamp formatting ([#1646])
  ### Added

- **fmt**, **time**: `LocalTime` and `UtcTime` types for formatting
  timestamps using the [`time` crate] ([#1646])
- **fmt**: Added a lifetime parameter to the `MakeWriter` trait,
  allowing it to return a borrowed writer. This enables implementations
  of `MakeWriter` for types such as `Mutex<T: io::Write>` and
  `std::fs::File`. ([#781])
- **env-filter**: Documentation improvements ([#1637])
- Support for some APIs on `#![no_std]` targets, by disabling the `std`
  feature flag ([#1660])
