tracing: prepare to release 0.1.18

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!

 ### 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!
