# 0.3.18 (November 13, 2023) This release of `tracing-subscriber` adds support for the [`NO_COLOR`] environment variable (an informal standard to disable emitting ANSI color escape codes) in `fmt::Layer`, reintroduces support for the [`chrono`] crate, and increases the minimum supported Rust version (MSRV) to Rust 1.63.0. It also introduces several minor API improvements. ### Added - **chrono**: Add [`chrono`] implementations of `FormatTime` ([#2690]) - **subscriber**: Add support for the [`NO_COLOR`] environment variable in `fmt::Layer` ([#2647]) - **fmt**: make `format::Writer::new()` public ([#2680]) - **filter**: Implement `layer::Filter` for `Option<Filter>` ([#2407]) ### Changed - **log**: bump version of `tracing-log` to 0.2 ([#2772]) - Increased minimum supported Rust version (MSRV) to 1.63.0+.

Utilities for implementing and composing tracing subscribers.
Compiler support: requires rustc 1.63+
Supported Rust Versions
Tracing is built against the latest stable release. The minimum supported version is 1.63. 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 1.69, the minimum supported version will not be increased past 1.66, 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.
