This changes `tracing-subscriber` so that the `env-filter`, `json`, and `chrono` features are not enabled by default, and instead require users to opt in. This should significantly reduce the default dependency footprint. Of course, this is a breaking change, and therefore will be part of `tracing-subscriber` v0.3.

# 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]) Thanks to @Folyd and @nmathewson for contributing to this release!

tracing-subscriberso that theenv-filter,json,and
chronofeatures are not enabled by default, and instead requireusers to opt in. This should significantly reduce the default
dependency footprint.
Of course, this is a breaking change, and therefore will be part of
