| # 0.1.29 (October 5th, 2021 |
| |
| This release adds support for recording `Option<T> where T: Value` as typed |
| `tracing` field values. It also includes significant performance improvements |
| for functions annotated with the `#[instrument]` attribute when the generated |
| span is disabled. |
| |
| ### Changed |
| |
| - `tracing-core`: updated to v0.1.21 |
| - `tracing-attributes`: updated to v0.1.19 |
| |
| ### Added |
| |
| - **field**: `Value` impl for `Option<T> where T: Value` ([#1585]) |
| - **attributes**: - improved performance when skipping `#[instrument]`-generated |
| spans below the max level ([#1600], [#1605], [#1614], [#1616], [#1617]) |
| |
| ### Fixed |
| |
| - **instrument**: added missing `Future` implementation for `WithSubscriber`, |
| making the `WithDispatch` extension trait actually useable ([#1602]) |
| - Documentation fixes and improvements ([#1595], [#1601], [#1597]) |
| |
| Thanks to @brianburgers, @mattiast, @DCjanus, @oli-obk, and @matklad for |
| contributing to this release! |

| # 0.1.28 (September 17th, 2021) |
| |
| This release fixes an issue where the RustDoc documentation was rendered |
| incorrectly. It doesn't include any actual code changes, and is very boring and |
| can be ignored. |
| |
| ### Fixed |
| |
| - **docs**: Incorrect documentation rendering due to unclosed `<div>` tag |
| ([#1572]) |
| |
| [#1572]: https://github.com/tokio-rs/tracing/pull/1572 |
| |
| # 0.1.27 (September 13, 2021) |
| |
| This release adds a new [`Span::or_current`] method to aid in efficiently |
| propagating span contexts to spawned threads or tasks. Additionally, it updates |
| the [`tracing-core`] version to [0.1.20] and the [`tracing-attributes`] version to |
| [0.1.16], ensuring that a number of new features in those crates are present. |
| |
| ### Fixed |
| |
| - **instrument**: Added missing `WithSubscriber` implementations for futures and |
| other types ([#1424]) |
| |
| ### Added |
| |
| - `Span::or_current` method, to help with efficient span context propagation |
| ([#1538]) |
| - **attributes**: add `skip_all` option to `#[instrument]` ([#1548]) |
| - **attributes**: record primitive types as primitive values rather than as |
| `fmt::Debug` ([#1378]) |
| - **core**: `NoSubscriber`, a no-op `Subscriber` implementation |
| ([#1549]) |
| - **core**: Added `Visit::record_f64` and support for recording floating-point |
| values ([#1507], [#1522]) |
| - A large number of documentation improvements and fixes ([#1369], [#1398], |
| [#1435], [#1442], [#1524], [#1556]) |
| |
| Thanks to new contributors @dzvon and @mbergkvist, as well as @teozkr, |

| - Symmetric `From` impls for existing `Into` impls on `span::Current`, `Span`, |
| and `Option<Id>` ([#1335], [#1338]) |
| - `From<EnteredSpan>` implementation for `Option<Id>`, allowing `EnteredSpan` to |
| be used in a `span!` macro's `parent:` field ([#1325]) |
| - `Attributes::fields` accessor that returns the set of fields defined on a |
| span's `Attributes` ([#1331]) |
| |

| # 0.1.25 (February 23, 2021) |
| |
| ### Added |
| |
| - `Span::entered` method for entering a span and moving it into a guard by value |

| |
| [#1108]: https://github.com/tokio-rs/tracing/pull/1108 |
| |
| # 0.1.21 (September 28, 2020) |
| |
| ### Fixed |
| |
| - Incorrect inlining of `Span::new`, `Span::new_root`, and `Span::new_child_of`, |
| which could result in `dispatcher::get_default` being inlined at the callsite |
| ([#994]) |
| - Regression where using a struct field as a span or event field when other |
| fields on that struct are borrowed mutably would fail to compile ([#987]) |
| |

| - Updated `tracing-core` to 0.1.17 ([#992]) |
| |
| ### Added |
| |

| # 0.1.20 (August 24, 2020) |
| |
| ### Changed |
| |
| - Significantly reduced assembly generated by macro invocations (#943) |
| - Updated `tracing-core` to 0.1.15 (#943) |
| |
| ### Added |
| |
| - Documented minimum supported Rust version policy (#941) |
| |
| # 0.1.19 (August 10, 2020) |
| |
| ### Fixed |
| |
| - Updated `tracing-core` to fix incorrect calculation of the global max level |
| filter (#908) |
| |
| ### Added |
| |
| - **attributes**: Support for using `self` in field expressions when |
| instrumenting `async-trait` functions (#875) |

| |
| Thanks to @anton-dutov, @nightmared, @mystor, and @toshokan for contributing to |

| |
| # 0.1.18 (July 31, 2020) |
| |
| ### Fixed |
| |
| - Fixed a bug where `LevelFilter::OFF` (and thus also the `static_max_level_off` |
| feature flag) would enable *all* traces, rather than *none* (#853) |
| - **log**: Fixed `tracing` macros and `Span`s not checking `log::max_level` |
| before emitting `log` records (#870) |
| |
| ### Changed |
| |
| - **macros**: Macros now check the global max level (`LevelFilter::current`) |
| before the per-callsite cache when determining if a span or event is enabled. |
| This significantly improves performance in some use cases (#853) |
| - **macros**: Simplified the code generated by macro expansion significantly, |
| which may improve compile times and/or `rustc` optimizatation of surrounding |
| code (#869, #869) |
| - **macros**: Macros now check the static max level before checking any runtime |
| filtering, improving performance when a span or event is disabled by a |
| `static_max_level_XXX` feature flag (#868) |
| - `LevelFilter` is now a re-export of the `tracing_core::LevelFilter` type, it |
| can now be used interchangably with the versions in `tracing-core` and |
| `tracing-subscriber` (#853) |
| - Significant performance improvements when comparing `LevelFilter`s and |
| `Level`s (#853) |
| - Updated the minimum `tracing-core` dependency to 0.1.12 (#853) |
| |
| ### Added |
| |
| - **macros**: Quoted string literals may now be used as field names, to allow |
| fields whose names are not valid Rust identifiers (#790) |
| - **docs**: Several documentation improvements (#850, #857, #841) |
| - `LevelFilter::current()` function, which returns the highest level that any |
| subscriber will enable (#853) |
| - `Subscriber::max_level_hint` optional trait method, for setting the value |
| returned by `LevelFilter::current()` (#853) |
| |
| Thanks to new contributors @cuviper, @ethanboxx, @ben0x539, @dignati, |
| @colelawrence, and @rbtcollins for helping out with this release! |
| |
| # 0.1.17 (July 22, 2020) |
| |
| ### Changed |
| |
| - **log**: Moved verbose span enter/exit log records to "tracing::span::active" |
| target, allowing them to be filtered separately (#833) |
| - **log**: All span lifecycle log records without fields now have the `Trace` |
| log filter, to guard against `log` users enabling them by default with blanket |
| level filtering (#833) |
| |
| ### Fixed |
| |
| - **log**/**macros**: Fixed missing implicit imports of the |
| `tracing::field::debug` and `tracing::field::display` functions inside the |
| macros when the "log" feature is enabled (#835) |
| |
| # 0.1.16 (July 8, 2020) |
| |
| ### Added |
| |
| - **attributes**: Support for arbitrary expressions as fields in `#[instrument]` (#672) |
| - **attributes**: `#[instrument]` now emits a compiler warning when ignoring unrecognized |
| input (#672, #786) |
| - Improved documentation on using `tracing` in async code (#769) |
| |
| ### Changed |
| |
| - Updated `tracing-core` dependency to 0.1.11 |
| |
| ### Fixed |
| |
| - **macros**: Excessive monomorphization in macros, which could lead to |
| longer compilation times (#787) |
| - **log**: Compiler warnings in macros when `log` or `log-always` features |
| are enabled (#753) |
| - Compiler error when `tracing-core/std` feature is enabled but `tracing/std` is |
| not (#760) |
| |
| Thanks to @nagisa for contributing to this release! |
| |
| # 0.1.15 (June 2, 2020) |
| |
| ### Changed |
| |
| - **macros**: Replaced use of legacy `local_inner_macros` with `$crate::` (#740) |
| |

| `Subscriber`, log records for spans now include span IDs (#613) |
| - **attributes**: Support for using `#[instrument]` on methods that are part of |
| [`async-trait`] trait implementations (#711) |
| - **attributes**: Optional `#[instrument(err)]` argument to automatically emit |
| an event if an instrumented function returns `Err` (#637) |
| - Added `#[must_use]` attribute to the guard returned by |
| `subscriber::set_default` (#685) |
| |
| ### Changed |
| |
| - **log**: Made [`log`] records emitted by spans much less noisy when span IDs are |
| not available (#613) |
| |
| ### Fixed |
| |
| - Several typos in the documentation (#656, #710, #715) |
| |
| Thanks to @FintanH, @shepmaster, @inanna-malick, @zekisharif, @bkchr, @majecty, |
| @ilana and @nightmared for contributing to this release! |
