Release notes

Sourced from tracing-subscriber's releases.

tracing-subscriber v0.3.0

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 explicitly (#1647). This means that RUST_LOG-based filters will not work unless the env-filter feature is enabled.

• 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 ([Transaction Fee Module #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

... (truncated)

Hmm ok, I don't think there's really a way to fix this yet until we figure out how to deal with the new Writer type. It is essentially a wrapper around a &mut dyn std::fmt::Writer, but there isn't an ability to construct a Writer from an existing std::fmt::Writer trait object, which is problematic for us since we can't do any buffering as seen in client/tracing/src/logging/event_format.rs.

[dependabot]

A newer version of tracing-subscriber exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
