tracing-subscriber 0.3.18

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.

• 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+.

tracing-log 0.2.0

This release contains two breaking changes: the removal of the env_logger
and trace_logger features. Below are the suggested migration paths:

• env_logger: users should use tracing_subscriber::fmt::Subscriber
  or tracing_subscriber::fmt::Layer with the Targets or
  EnvFilter filters instead.
• trace_logger: users should use the tracing crate's
  "log" feature flag instead.

Breaking Changes

• Remove deprecated env_logger feature. This removes the dependency
  on the unmaintained atty crate, resolving the security advisory
  GHSA-g98v-hv3f-hcfr/RUSTSEC-2021-0145. (#2771)
• Remove deprecated trace_logger feature. (#2771)

tracing 0.1.40

This release fixes a potential stack use-after-free in the
Instrument::into_inner method. Only uses of this method are affected by this
bug.

Fixed

• Use mem::ManuallyDrop instead of mem::forget in Instrument::into_inner
  (#2765)
