 105 # 0.1.20 (August 24, 2020)
 106

 110 - Updated `tracing-core` to 0.1.15 (#943)
 111
 112 ### Added

 121   filter (#908)
 122

 126   instrumenting `async-trait` functions (#875)

 131
 132 # 0.1.18 (July 31, 2020)
 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)

 225

 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
 238
 239 - **log**: Made [`log`] records emitted by spans much less noisy when span IDs are
 240  not available (#613)
 241
 242 ### Fixed
 243
 244 - Several typos in the documentation (#656, #710, #715)
