0.2.12 (August 10, 2020)

0.2.10 (July 31, 2020)

Fixed

• docs: Incorrect formatting (#862)

Changed

• filter: LevelFilter is now a re-export of the tracing_core::LevelFilter type, it can now be used interchangeably with the versions in tracing and tracing-core (#853)
• filter: Significant performance improvements when comparing LevelFilters and Levels (#853)
• Updated the minimum tracing-core dependency to 0.1.12 (#853)

Added

• filter: LevelFilter and EnvFilter now participate in tracing-core's max level hinting, improving performance significantly in some use cases where levels are disabled globally (#853)

Fixed

• fmt: Fixed compilation failure on MSRV when the chrono feature is disabled (#844)

Added

0.2.8 (July 17, 2020)

Changed

• fmt: When the chrono dependency is enabled, the SystemTime timestamp formatter now emits human-readable timestamps rather than using SystemTime's fmt::Debugimplementation (chrono is still required for customized timestamp formatting) (#807)
• ansi: Updated ansi_term dependency to 0.12 (#816)

Added

• json: with_span_list method to configure the JSON formatter to include a list of all spans in the current trace in formatting events (similarly to the text formatter) (#741)
• json: with_current_span method to configure the JSON formatter to include a field for the current span (the leaf of the trace) in formatted events (#741)
• fmt: with_thread_names and with_thread_ids methods to configure fmt::Subscribers and fmt::Layers to include the thread name and/or thread ID of the current thread when formatting events (#818)

• Documentation clarification and improvement (#762, #769)

Thanks to @rkuhn, @greenwoodcm, and @Ralith for contributing to this release!

This release includes several API ergonomics improvements, including shorthand constructors for many types, and an extension trait for initializing subscribers using method-chaining style. Additionally, several bugs in less commonly used fmt APIs were fixed.

Added

• fmt: Shorthand free functions for constructing most types in fmt (including tracing_subscriber::fmt() to return a SubscriberBuilder, tracing_subscriber::fmt::layer() to return a format Layer, etc) (#660)

• Added SubscriberInitExt extension trait for more ergonomic subscriber initialization (#660)

Changed

• fmt: Moved LayerBuilder methods to Layer (#655)

Deprecated

• fmt: LayerBuilder, as Layer now implements all builder methods (#655)

Fixed

• fmt: Fixed Compact formatter not omitting levels with with_level(false) (#657)
• fmt: Fixed fmt::Layer duplicating the fields for a new span if another layer has already formatted its fields (#634)

0.2.2 (February 27, 2020)

Added

• fmt: Added flatten_event to SubscriberBuilder (#599)
• fmt: Added with_level to SubscriberBuilder (#594)

Fixed

• filter: Fixed EnvFilter incorrectly allowing less-specific filter directives to enable events that are disabled by more-specific filters (#583)
• filter: Multiple significant EnvFilter performance improvements, especially when filtering events generated by log records (#578, #583)

0.1.6 (October 29, 2019)

Added

• Add init and try_init functions to FmtSubscriber (#385)
• Add ChronoUtc and ChronoLocal timers, RFC 3339 support (#387)
• Add tracing::subscriber::set_default which sets the default subscriber and returns a drop guard. This drop guard will reset the dispatch on drop (#388).

Fixed

• Fix default level for EnvFilter. Setting RUST_LOG=target previously only the ERROR level, while it should enable everything. tracing-subscriber now defaults to TRACE if no level is specified (#401)
• Fix tracing-log feature flag for init + try_init. The feature flag tracing_log was used instead of the correct tracing-log. As a result, both tracing-log and tracing_log needed to be specified in order to initialize the global logger. Only tracing-log needs to be specified now (#400).
