65 | # 0.1.22 (November 23, 2020) |
66 | ||
67 | ### Changed | |
68 | ||
69 | - Updated `pin-project-lite` dependency to 0.2 ([#1108]) | |
70 | ||
71 | [#1108]: https://github.com/tokio-rs/tracing/pull/1108 | |
72 | ||
73 | # 0.1.21 (September 28, 2020) | |
74 | ||
75 | ### Fixed | |
76 | ||
77 | - Incorrect inlining of `Span::new`, `Span::new_root`, and `Span::new_child_of`, | |
78 | which could result in `dispatcher::get_default` being inlined at the callsite | |
79 | ([#994]) | |
80 | - Regression where using a struct field as a span or event field when other | |
81 | fields on that struct are borrowed mutably would fail to compile ([#987]) | |
82 | ||
83 | ### Changed | |
84 | ||
85 | - Updated `tracing-core` to 0.1.17 ([#992]) | |
86 | ||
87 | ### Added | |
88 | ||
89 | - `Instrument` trait and `Instrumented` type for attaching a `Span` to a | |
90 | `Future` ([#808]) | |
91 | - `Copy` implementations for `Level` and `LevelFilter` ([#992]) | |
92 | - Multiple documentation fixes and improvements ([#964], [#980], [#981]) | |
93 | ||

115 | ||
3dfed10e XL |
116 | # 0.1.19 (August 10, 2020) |
117 | ||
118 | ### Fixed | |
119 | ||
120 | - Updated `tracing-core` to fix incorrect calculation of the global max level | |
121 | filter (#908) | |
122 | ||
123 | ### Added | |

126 | instrumenting `async-trait` functions (#875) | |
127 | - Several documentation improvements (#832, #881, #896, #897, #911, #913) | |
128 | ||
129 | Thanks to @anton-dutov, @nightmared, @mystor, and @toshokan for contributing to | |
130 | this release! | |
131 | ||
5869c6ff | 132 | # 0.1.18 (July 31, 2020) |
3dfed10e XL |
133 | |
134 | ### Fixed | |
135 | ||
136 | - Fixed a bug where `LevelFilter::OFF` (and thus also the `static_max_level_off` | |
137 | feature flag) would enable *all* traces, rather than *none* (#853) | |
138 | - **log**: Fixed `tracing` macros and `Span`s not checking `log::max_level` | |
139 | before emitting `log` records (#870) | |
140 | ||
141 | ### Changed | |
142 | ||
143 | - **macros**: Macros now check the global max level (`LevelFilter::current`) | |
144 | before the per-callsite cache when determining if a span or event is enabled. | |
145 | This significantly improves performance in some use cases (#853) | |
146 | - **macros**: Simplified the code generated by macro expansion significantly, | |
147 | which may improve compile times and/or `rustc` optimizatation of surrounding | |
148 | code (#869, #869) | |
149 | - **macros**: Macros now check the static max level before checking any runtime | |
150 | filtering, improving performance when a span or event is disabled by a | |
151 | `static_max_level_XXX` feature flag (#868) | |
152 | - `LevelFilter` is now a re-export of the `tracing_core::LevelFilter` type, it | |
153 | can now be used interchangably with the versions in `tracing-core` and | |
154 | `tracing-subscriber` (#853) | |
155 | - Significant performance improvements when comparing `LevelFilter`s and | |
156 | `Level`s (#853) | |
157 | - Updated the minimum `tracing-core` dependency to 0.1.12 (#853) | |
158 | ||
159 | ### Added | |
160 | ||
161 | - **macros**: Quoted string literals may now be used as field names, to allow | |
162 | fields whose names are not valid Rust identifiers (#790) | |
163 | - **docs**: Several documentation improvements (#850, #857, #841) | |
164 | - `LevelFilter::current()` function, which returns the highest level that any | |
165 | subscriber will enable (#853) | |
166 | - `Subscriber::max_level_hint` optional trait method, for setting the value | |
167 | returned by `LevelFilter::current()` (#853) | |
168 | ||
169 | Thanks to new contributors @cuviper, @ethanboxx, @ben0x539, @dignati, | |
170 | @colelawrence, and @rbtcollins for helping out with this release! | |
171 | ||
172 | # 0.1.17 (July 22, 2020) | |
173 | ||
174 | ### Changed | |
175 | ||
176 | - **log**: Moved verbose span enter/exit log records to "tracing::span::active" | |
177 | target, allowing them to be filtered separately (#833) | |
178 | - **log**: All span lifecycle log records without fields now have the `Trace` | |
179 | log filter, to guard against `log` users enabling them by default with blanket | |
180 | level filtering (#833) | |
181 | ||
182 | ### Fixed | |
183 | ||
184 | - **log**/**macros**: Fixed missing implicit imports of the | |
185 | `tracing::field::debug` and `tracing::field::display` functions inside the | |
186 | macros when the "log" feature is enabled (#835) | |
187 | ||
188 | # 0.1.16 (July 8, 2020) | |
189 | ||
190 | ### Added | |
191 | ||
192 | - **attributes**: Support for arbitrary expressions as fields in `#[instrument]` (#672) | |
193 | - **attributes**: `#[instrument]` now emits a compiler warning when ignoring unrecognized | |
194 | input (#672, #786) | |
195 | - Improved documentation on using `tracing` in async code (#769) | |
196 | ||
197 | ### Changed | |
198 | ||
199 | - Updated `tracing-core` dependency to 0.1.11 | |
200 | ||
201 | ### Fixed | |
202 | ||
203 | - **macros**: Excessive monomorphization in macros, which could lead to | |
204 | longer compilation times (#787) | |
205 | - **log**: Compiler warnings in macros when `log` or `log-always` features | |
206 | are enabled (#753) | |
207 | - Compiler error when `tracing-core/std` feature is enabled but `tracing/std` is | |
208 | not (#760) | |
209 | ||
210 | Thanks to @nagisa for contributing to this release! | |

229 | `Subscriber`, log records for spans now include span IDs (#613) | |
230 | - **attributes**: Support for using `#[instrument]` on methods that are part of | |
231 | [`async-trait`] trait implementations (#711) | |
232 | - **attributes**: Optional `#[instrument(err)]` argument to automatically emit | |
233 | an event if an instrumented function returns `Err` (#637) | |
234 | - Added `#[must_use]` attribute to the guard returned by | |
235 | `subscriber::set_default` (#685) | |
236 | ||
237 | ### Changed | |

253 | ||
254 | ### Added | |
255 | ||
256 | - **field**: `field::Empty` type for declaring empty fields whose values will be | |

259 | numbers (#538) | |
260 | - **attributes**: Support for adding arbitrary literal fields to spans generated | |
261 | by `#[instrument]` (#569) | |
