tracing-appender 0.2.3

This release contains several new features. It also increases the
minimum supported Rust version (MSRV) to Rust 1.63.0.

Added

• rolling: add option to automatically delete old log files (#2323)
• non_blocking: allow worker thread name to be configured (#2365)
• rolling: add a builder for constructing RollingFileAppenders (#2227)
• rolling: add Builder::filename_suffix parameter (#2225)
• non_blocking: remove Sync bound from writer for NonBlocking (#2607)
• non_blocking: name spawned threads (#2219)

Fixed

• Fixed several documentation typos and issues (#2689, #2375)

Changed

• Increased minimum supported Rust version (MSRV) to 1.63.0+ (#2793)
• Updated minimum tracing-subscriber version to 0.3.18 (#2790)

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-log 0.1.4

Changes

• Deprecated env_logger feature in favor of tracing_subscriber::fmt::Subscriber ([#2752])

#[2752]: #2752

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)

Thanks to @cramertj and @Manishearth for finding and fixing this issue!

Changed

• Bump minimum version of proc-macro2 to 1.0.60 (#2732)
• Generate less dead code for async block return type hint (#2709)

tracing 0.1.39

This release adds several additional features to the tracing macros. In
addition, it updates the tracing-core dependency to v0.1.32 and
the tracing-attributes dependency to v0.1.27.

Added

• Allow constant field names in macros (#2617)
• Allow setting event names in macros (#2699)
• core: Allow ValueSets of any length (#2508)

Changed

• attributes: Generate less dead code for async block return type hint (#2709)

Fixed

• Use fully qualified names in macros for items exported from std prelude
  (#2621, #2757)
• attributes: Allow [clippy::let_with_type_underscore] in macro-generated
  code ([#2609])
• attributes: Allow unknown_lints in macro-generated code (#2626)
• attributes: Fix a compilation error in #[instrument] when the "log"
  feature is enabled (#2599)

Documented

• Add axum-insights to relevant crates. (#2713)
• Fix link to RAI pattern crate documentation ([#2612])
• Fix docs typos and warnings (#2581)
• Add clippy-tracing to related crates (#2628)
• Add tracing-cloudwatch to related crates (#2667)
• Fix deadlink to tracing-etw repo (#2602)

tracing-attributes 0.1.26

This release of tracing-attributes fixes warnings due to allow attributes in
generated code that allow lints which may not exist on earlier versions of rustc.

Fixed

• Allow unknown_lints in macro-generated code ([#2626])

Thanks to @mladedav for contributing to this release!

tracing-attributes 0.1.25

This release of tracing-attributes fixes the Clippy lint
let_with_type_underscore in code generated by the #[instrument]
attribute in Rust 1.70+.

Fixed

• Allow [clippy::let_with_type_underscore] in macro-generated code (#2609)

Thanks to @coolreader19 for contributing to this release!

tracing-core 0.1.31

This release of tracing-core fixes a bug that caused threads which call
dispatcher::get_default before a global default subscriber is set to never
see the global default once it is set. In addition, it includes improvements for
instrumentation performance in some cases, especially when using a global
default dispatcher.

Fixed

• Fixed incorrect thread-local caching of Dispatch::none if
  dispatcher::get_default is called before dispatcher::set_global_default
  (#2593)

Changed

• Cloning a Dispatch that points at a global default subscriber no longer
  requires an Arc reference count increment, improving performance
  substantially (#2593)
• dispatcher::get_default no longer attempts to access a thread local if the
  scoped dispatcher is not in use, improving performance when the default
  dispatcher is global (#2593)
• Added #[inline] annotations called by the event! and span! macros to
  reduce the size of macro-generated code and improve recording performance
  (#2555)

Thanks to new contributor @ldm0 for contributing to this release!
