# 0.3.10 (Apr 1, 2022) This release adds several new features, including a `Filter` implementation and new builder API for `EnvFilter`, support for using a `Vec<L> where L: Layer` as a `Layer`, and a number of smaller API improvements to make working with dynamic and reloadable layers easier. ### Added - **registry**: Implement `Filter` for `EnvFilter`, allowing it to be used with per-layer filtering ([#1983]) - **registry**: `Filter::on_new_span`, `Filter::on_enter`, `Filter::on_exit`, `Filter::on_close` and `Filter::on_record` callbacks to allow `Filter`s to track span states internally ([#1973], [#2017], [#2031]) - **registry**: `Filtered::filter` and `Filtered::filter_mut` accessors ([#1959]) - **registry**: `Filtered::inner` and `Filtered::inner_mut` accessors to borrow the wrapped `Layer` ([#2034]) - **layer**: Implement `Layer` for `Vec<L: Layer>`, to allow composing together a dynamically sized list of `Layer`s ([#2027]) - **layer**: `Layer::boxed` method to make type-erasing `Layer`s easier ([#2026]) - **fmt**: `fmt::Layer::writer` and `fmt::Layer::writer_mut` accessors ([#2034]) - **fmt**: `fmt::Layer::set_ansi` method to allow changing the ANSI formatting configuration at runtime ([#2034]) - **env-filter**: `EnvFilter::builder` to configure a new `EnvFilter` prior to parsing it ([#2035]) - Several documentation fixes and improvements ([#1972], [#1971], [#2023], [#2023]) ### Fixed - **fmt**: `fmt::Layer`'s auto traits no longer depend on the `Subscriber` type parameter's auto traits ([#2025]) - **env-filter**: Fixed missing help text when the `ansi` feature is disabled ([#2029]) Thanks to new contributors @TimoFreiberg and @wagenet, as well as @CAD97 for contributing to this release!

Compiler support: requires rustc 1.49+
Supported Rust Versions
Tracing is built against the latest stable release. The minimum supported version is 1.49. The current Tracing version is not guaranteed to build on Rust versions earlier than the minimum supported version.
Tracing follows the same compiler support policies as the rest of the Tokio project. The current stable Rust compiler and the three most recent minor versions before it will always be supported. For example, if the current stable compiler version is 1.45, the minimum supported version will not be increased past 1.42, three minor versions prior. Increasing the minimum supported compiler version is not considered a semver breaking change as long as doing so complies with this policy.
