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!

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)

• core: Allow ValueSets of any length (#2508)

Changed

• tracing-core: updated to 0.1.32
• attributes: Bump minimum version of proc-macro2 to 1.0.60 (#2732)
• 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)

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!

tracing 0.1.38

This tracing release changes the Drop implementation for Instrumented
Futures so that the attached Span is entered when dropping the Future. This
means that events emitted by the Future's Drop implementation will now be
recorded within its Span. It also adds #[inline] hints to methods called in
the event! macro's expansion, for an improvement in both binary size and
performance.

Additionally, this release updates the tracing-attributes dependency to
v0.1.24, which updates the syn dependency to v2.x.x.
tracing-attributes v0.1.24 also includes improvements to the #[instrument]
macro; see the tracing-attributes 0.1.24 release notes for
details.

Added

• Instrumented futures will now enter the attached Span in their Drop
  implementation, allowing events emitted when dropping the future to occur
  within the span (#2562)
• #[inline] attributes for methods called by the event! macros, making
  generated code smaller (#2555)
• attributes: level argument to #[instrument(err)] and
  #[instrument(ret)] to override the level of
  the generated return value event (#2335)
• attributes: Improved compiler error message when #[instrument] is added to a const fn
  (#2418)

Changed

• tracing-attributes: updated to 0.1.24
• Removed unneeded cfg-if dependency (#2553)
• attributes: Updated syn dependency to 2.0 (#2516)

Fixed

• attributes: Fix clippy::unreachable warnings in #[instrument]-generated code (#2356)
• attributes: Removed unused "visit" feature flag from syn dependency (#2530)

Documented

• attributes: Documented default level for #[instrument(err)] (#2433)
• attributes: Improved documentation for levels in #[instrument] (#2350)
