with the return value of an instrumented function.

tracing 0.1.30

This release adds experimental support for recording structured field
values using the valuable crate. See this blog post for
details on valuable.

Note that valuable support currently requires --cfg tracing_unstable. See
the documentation for details.

This release also adds a new enabled! macro for testing if a span or event
would be enabled.

Added

• field: Experimental support for recording field values using the
  valuable crate (#1608, #1888, #1887)
• enabled! macro for testing if a span or event is enabled (#1882)

Changed

• tracing-core: updated to 0.1.22
• tracing-attributes: updated to 0.1.19

Fixed

• log: Fixed "use of moved value" compiler error when the "log" feature is
  enabled (#1823)
• Fixed macro hygiene issues when used in a crate that defines its own concat!
  macro (#1842)
• A very large number of documentation fixes and improvements.

Thanks to @@vlad-scherbina, @Skepfyr, @Swatinem, @guswynn, @teohhanhui,
@xd009642, @tobz, @d-e-s-o@0b01, and @nickelc for contributing to this release!

tracing-subscriber 0.3.7

This release adds combinators for combining filters.

Additionally, this release also updates the thread-local crate to v1.1.4,
fixing warnings for the security advisory RUSTSEC-2022-0006. Note that
previous versions of tracing-subscriber did not use any of the thread-local
crate's APIs effected by the vulnerability. However, updating the version fixes
warnings emitted by cargo audit and similar tools.

Added

Fixed

• registry: Updated thread-local to v1.1.4 (#1858)

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

tracing-subscriber 0.3.6

This release adds configuration options to tracing_subscriber::fmt to log
source code locations for events.

  configuration methods to fmt::Format, fmt::SubscriberBuilder, and
  fmt::Layer (#1773)

Fixed

• fmt: Removed incorrect leading comma from span fields with the Pretty
  formatter (#1833)

Deprecated

• fmt: Deprecated Pretty::with_source_location, as it can now be replaced
  by the more general Format, SubscriberBuilder, and Layer methods
  (#1773)

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

tracing-journald 0.2.2

Added

  timestamps with a fixed offset (#1772)

Fixed

• fmt: Added a Targets filter to fmt::init() and fmt::try_init() when
  the "env-filter" feature is disabled, so that RUST_LOG is still honored
  (#1781)

Thanks to @marienz and @ishitatsuyuki for contributing to this release!

tracing-journald 0.2.1
